A magnitude 5.7 earthquake struck Northern California on Thursday night and was felt across a large area, according to officials.
The quake was occurred around 8:47 p.m., and its epicenter was 27 miles southwest of Susanville and seven miles west northwest of Greenville, about 150 miles northeast of Sacramento, and zero feet deep, according to the U.S. Geological Survey.
A Chico resident told The Times that he felt a slow steady roll that lasted about 30 seconds. People on Twitter reported feeling the quake in Sacramento.
Smaller earthquakes followed, including a magnitude 3.5 temblor at 8:55 p.m.

Tectonic Summary
The May 23, 2013 Mw 7.4 earthquake southwest of Vaini, Tonga, occurred as a result of normal faulting at a depth of approximately 170 km. At the location of this earthquake, the Pacific and Australia plates are converging at a rate of approximately 73 mm/yr in an east-west direction, resulting in the westward subduction of the Pacific plate beneath Tonga at the Tonga-Kermadec trench. The depth and faulting mechanism of the May 23rd earthquake indicate it ruptured a fault within the subducting Pacific lithosphere rather than on the shallower thrust interface between the two plates.
The Tonga-Kermadec arc has frequent moderate-to-large earthquakes, and has hosted over a dozen M6.5+ earthquakes within 500 km of the May 23rd earthquake over the past 40 years. Most of these also occurred at intermediate depths; the largest was an Mw 7.7 earthquake in October of 1997, approximately 110 km to the north-northeast of the May 23 2013 event. None are known to have caused significant damage. Intermediate-depth (70-300 km) and deep-focus (depth > 300 km) earthquakes are distinguished from shallow earthquakes (0-70 km) by the nature of their tectonic setting, and are in general less hazardous than their shallow counterparts, though they may be felt at great distances from their epicenters. The Tonga-Kermadec slab in the region of the May 23 2013 earthquake is seismically active to depths of over 650 km.
Seismotectonics of the Eastern Margin of the Australia Plate
The eastern margin of the Australia plate is one of the most sesimically active areas of the world due to high rates of convergence between the Australia and Pacific plates. In the region of New Zealand, the 3000 km long Australia-Pacific plate boundary extends from south of Macquarie Island to the southern Kermadec Island chain. It includes an oceanic transform (the Macquarie Ridge), two oppositely verging subduction zones (Puysegur and Hikurangi), and a transpressive continental transform, the Alpine Fault through South Island, New Zealand.
Since 1900 there have been 15 M7.5+ earthquakes recorded near New Zealand. Nine of these, and the four largest, occurred along or near the Macquarie Ridge, including the 1989 M8.2 event on the ridge itself, and the 2004 M8.1 event 200 km to the west of the plate boundary, reflecting intraplate deformation. The largest recorded earthquake in New Zealand itself was the 1931 M7.8 Hawke's Bay earthquake, which killed 256 people. The last M7.5+ earthquake along the Alpine Fault was 170 years ago; studies of the faults' strain accumulation suggest that similar events are likely to occur again.
North of New Zealand, the Australia-Pacific boundary stretches east of Tonga and Fiji to 250 km south of Samoa. For 2,200 km the trench is approximately linear, and includes two segments where old (>120 Myr) Pacific oceanic lithosphere rapidly subducts westward (Kermadec and Tonga). At the northern end of the Tonga trench, the boundary curves sharply westward and changes along a 700 km-long segment from trench-normal subduction, to oblique subduction, to a left lateral transform-like structure.
Australia-Pacific convergence rates increase northward from 60 mm/yr at the southern Kermadec trench to 90 mm/yr at the northern Tonga trench; however, significant back arc extension (or equivalently, slab rollback) causes the consumption rate of subducting Pacific lithosphere to be much faster. The spreading rate in the Havre trough, west of the Kermadec trench, increases northward from 8 to 20 mm/yr. The southern tip of this spreading center is propagating into the North Island of New Zealand, rifting it apart. In the southern Lau Basin, west of the Tonga trench, the spreading rate increases northward from 60 to 90 mm/yr, and in the northern Lau Basin, multiple spreading centers result in an extension rate as high as 160 mm/yr. The overall subduction velocity of the Pacific plate is the vector sum of Australia-Pacific velocity and back arc spreading velocity: thus it increases northward along the Kermadec trench from 70 to 100 mm/yr, and along the Tonga trench from 150 to 240 mm/yr.
The Kermadec-Tonga subduction zone generates many large earthquakes on the interface between the descending Pacific and overriding Australia plates, within the two plates themselves and, less frequently, near the outer rise of the Pacific plate east of the trench. Since 1900, 40 M7.5+ earthquakes have been recorded, mostly north of 30°S. However, it is unclear whether any of the few historic M8+ events that have occurred close to the plate boundary were underthrusting events on the plate interface, or were intraplate earthquakes. On September 29, 2009, one of the largest normal fault (outer rise) earthquakes ever recorded (M8.1) occurred south of Samoa, 40 km east of the Tonga trench, generating a tsunami that killed at least 180 people.
Across the North Fiji Basin and to the west of the Vanuatu Islands, the Australia plate again subducts eastwards beneath the Pacific, at the North New Hebrides trench. At the southern end of this trench, east of the Loyalty Islands, the plate boundary curves east into an oceanic transform-like structure analogous to the one north of Tonga.
Australia-Pacific convergence rates increase northward from 80 to 90 mm/yr along the North New Hebrides trench, but the Australia plate consumption rate is increased by extension in the back arc and in the North Fiji Basin. Back arc spreading occurs at a rate of 50 mm/yr along most of the subduction zone, except near ~15°S, where the D'Entrecasteaux ridge intersects the trench and causes localized compression of 50 mm/yr in the back arc. Therefore, the Australia plate subduction velocity ranges from 120 mm/yr at the southern end of the North New Hebrides trench, to 40 mm/yr at the D'Entrecasteaux ridge-trench intersection, to 170 mm/yr at the northern end of the trench.
Large earthquakes are common along the North New Hebrides trench and have mechanisms associated with subduction tectonics, though occasional strike slip earthquakes occur near the subduction of the D'Entrecasteaux ridge. Within the subduction zone 34 M7.5+ earthquakes have been recorded since 1900. On October 7, 2009, a large interplate thrust fault earthquake (M7.6) in the northern North New Hebrides subduction zone was followed 15 minutes later by an even larger interplate event (M7.8) 60 km to the north. It is likely that the first event triggered the second of the so-called earthquake "doublet".

New York Earthquake May Have Caused Mysterious Boom
Residents of Little Compton, Tiverton and Westport might have felt seismic activity from a relatively small earthquake in upstate New York on Wednesday evening.
Randy Smith said he has been hearing loud booms near his house for about two years and most recently last week three booms shook his house and startled his dog, Sandy. (Scott DeSmit/Daily News)
Posted: Saturday, March 16, 2013 12:06 am | Updated: 3:18 pm, Sat Mar 16, 2013.
ALABAMA — It was about midnight on a night last week when Randy Smith took his dog outside and for the third time this year, heard the mysterious booms.
“Three times in a row I heard it,” Smith said. “It sounds as loud as a sonic boom. Maybe louder. As soon as it goes off, the dog starts growling and gets startled.”
Smith and his father, Laverne Smith, live at 748 Lewiston Rd. (Route 77) and have been hearing the booms for nearly two years now.
They cannot pinpoint the source of the noise.
“You can’t tell what direction it’s coming from,” Laverne Smith, 76, said. “The last good weather we had I was out near the shed and heard it.”
Last year they heard the booms about 10 times, sometimes during the day and sometimes at night.
“It seems to be just around here,” Randy Smith said. “I asked my sister who lives in Alabama Center and she hasn’t heard it.”
It is a phenomena that has sparked curiosity throughout the country for several years now.
The booms, however, have grown more frequent.
In December, people in Rhode Island, Alabama, Georgia, Texas and Oklahoma reported hearing unusual booms and explosions.
Newspaper reports revealed no unusual seismic activity in those regions and all the noises have yet to be explained.
In January, hundreds of people in northern Utah called emergency dispatchers reporting booms and shaking of the earth.
The cause remains a mystery, though the Air Force said it had done training exercises, dropping bombs in the desert.
Locally, 911 dispatchers in Chautauqua County were inundated with calls on Jan. 13, all reporting hearing a loud boom that shook houses.
Police eventually determined the noise came from a 20-year-old man using an explosive called Tannerite, a legal compound that when struck with a bullet explodes.
A few days later, on Jan. 16, residents in Gorham, Ontario County, reported a series of booms.
“It was just a loud, explosion-like sound,” Janet Koller told the Canandaigua Messenger Post. “We saw nothing. It was dark by then. It was hard to even tell what direction it came from. It shook the house.”
Ontario County sheriff’s officials said several people called to report the still unexplained booms.
Booms also were reported in Le Roy.
Former Daily News editor Ben Beagle said he was in his living room about 9 p.m. March 9 when he heard “some booms.”
“I thought it was just neighbors, maybe shutting doors or something. Then, about 9:09 p.m., a series of boom-boom-booms that I thought must be thunder.”
He checked the weather radar and all was clear, he said.
Genesee County Senior Dispatcher Gary Diegelman said the county’s 911 system did not receive any reports of booms.
He offered a few possible explanations for booms, at least those heard during the day.
Diegelman said the federal Bureau of Alcohol, Tobacco and Firearms often uses stone quarries in Le Roy and Alabama for training and detonating explosives.
“We’ve had them coming in the past few years and they probably make a good-sized blast,” he said. “At night, it’s possible it’s propane cannons they use on farms to scare away animals.”
Those, however, are usually heard during the spring and early summer when crops are planted are in various stages of growth.
Three farmers contacted this week reported they do not use propane cannons and weren’t aware of any local farmers that do, at least at this time of year.
So what’s going on?
Dr. Mark Castner, director of Braun-Ruddick Seismograph Station at Canisius College, told WIVB-TV in Buffalo that booms can be associated with an earthquake, quarry blasts, building implosions or sonic booms.
Seismographic records reported no unusual activity, however, and officials at Niagara Falls Air Reserve have had no aircraft flying in the area during the times of the reported booms.
The Smiths live near National Fuel’s Empire Pipeline for natural gas.
Could that be an explanation?
No, says spokeswoman Karen Merkel.
“I checked and we have no issues with the pipeline, we’re not doing any testing and we have no reported leaks,” she said. “We have nothing going on but we do want to be aware of it.”
The Smiths have no idea what causes the booms around their house.
“It doesn’t sound like gunfire or an explosion,” Randy Smith, 53, said. “It’s huge and it rattles everything in the house. I’ve looked around for lights or aircraft but I never see anything. I wish I could tell you I’ve seen lights for an aircraft but I can’t.”
Mysterious Boom Shakes Houses Across Tiverton, Little Compton, Westport
Residents across the three seaside communities reported hearing a loud boom that shook their entire houses last night.
A number of Little Compton, Tiverton and Wesport residents reported hearing - and feeling - a loud mysterious boom at about 8:40 p.m. on Wednesday.
Little Compton Police Chief Sidney Wordell received two 911 calls about the mystery boom.
"We did receive a couple of calls last night and and we checked in with Westport and Tiverton as well," said Wordell. "They had similar reports as they received a couple of calls as well."
Wordell noted that neither Little Compton or its neighboring police departments received any reports of explosions, and callers who experienced the mysterious boom also noted a lack of noise associated with the brief shaking feeling.
"We were sitting there watching TV and it felt like a full size tree landed right outside the window." said Chris S. Pinkerton, who lives in north Little Compton by the Stone Church. "It was one big boom, there wasn't any noise, but the entire house shook."
At first, Pinkerton and his wife speculated the wind was to blame - that was until a friend who lives five miles away near the Little Compton Commons posted a message on Facebook. She too was wondering what just caused her house to shake.
"I wouldn't have thought anything about it, but between ourselves and our friends, living so far apart - and no noise with it - I've heard a sonic boom before and it was nothing like that," said Pinkerton.
Pinkerton described it as a quick thump and said he felt his whole house shake for a moment.
"My guess is it either had to be some kind of earthquake or fighter jet that broke sound barrier," said Pinkerton.
"We live in So. Tiverton off Crandall Rd. It was a muffled boom and house shook for a second," saidCathleen Ronayne Oblinger. "Too short to be a quake. My daughter and I looked at each other and both said 'What was that!'"
Another Crandall Road resident, Robin Marshall, however, said she didn't feel a thing.
"I'm near the high school off of Brayton Road," said Michelle Maczka. "For speculation, that type of sound/shaking is usually associated with an explosion of some sort."
Within 30 minutes, more than a half dozen readers responded to Tiverton-Little Compton Patch's post about the mysterious boom.

Another small town in Wisconsin is hearing booms but this time they’re being accompanied by lights. That’s odd because I thought the booms were coming from the ground. What do lights in the sky have to do with booms in the ground. There were no reports of thunderstorms and the National Weather Service can’t make any connection in terms of weather. The lights were observed BEFORE the booms.
“I observed a large flash of light followed by a ‘boom,’” the officer wrote in his report. “I advised dispatch of this information and my belief that it was possibly a transformer.”
However, Sauk County Sheriff’s Department dispatchers contacted Alliant Energy, and reported the company knew of no power outages in the Baraboo area.
Is this related to earthquakes as they say occurred in Clintonville. There is something called “earthquake lights”.
From wiki:
An earthquake light is an unusual luminous aerial phenomenon that reportedly appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions.
Clintonville, Montello and Baraboo
From what I read, it would occur during a real earthquake. The wiki definition says nothing about flashes of light followed by booms. Earthquake lights are not well understood but you can read more at the link here. The lights don’t make any sense because the booms are supposedly coming from the ground.
Now we have booms in Clintonville, Montello and Baraboo. The events seem to be on a path.
Why aren't scientists looking at the study that has been going on regarding the pole shift, the destabilization of the Earth's core and the skyquakes?
Here is the update that includes recorded audio of the booming events....
Second Wisconsin Town Reports Booming Sounds
BARABOO, Wis. -- A second Wisconsin town has reported hearing booming sounds.
Residents of Baraboo, located north of Madison, began calling 911 early Sunday morning after seeing two separate flashes of light followed by loud booms.
"I just heard an explosion go off somewhere," one caller said.
A police officer witnessed the first flash while parked along a street. He said he thought an electrical transformer had failed.
"When those things go off, they make a really loud pop," police chief Mark Schauf said. "Usually there's a flash of light as they're surging off the electricity."
The local utility said it had no outages or transformer failures on Sunday night.
Clintonville, Wisconsin Booms: City Hires Firm To Explore Mysterious Noises
First Posted: 03/22/2012 2:42 pmUpdated: 03/22/2012 5:43 pm
CLINTONVILLE, Wis. (AP) — An eastern Wisconsin town where unexplained booms have kept some residents up at night will hire an engineering firm to explore the cause of the racket, the city's administrator said Thursday.
The Waukesha engineering firm Ruekert & Mielke will install ground seismology monitors in four places around the town late Thursday or early Friday, Clintonville administrator Lisa Kuss said.
"The purpose is trying to determine some sort of epicenter to the event," Kuss said. "If you can do that, then you can focus on how deep it is."
The engineers will set three monitors up in a triangle, with the fourth in the middle, and they will stay in place until they produce a clear reading of seismological activity, Kuss said. She didn't know how long the tests would take.
The city has authorized $1,000 to rent the machines and up to $6,000 for analysis.
Dozens of residents began reporting the loud booms on Sunday night. Some said it sounded like an explosion, others that is was more like a door being slammed. Some cited fireworks, others wondered if they had experienced an earthquake.
The complaints continued on Monday night and more came just before dawn on Wednesday. Police received a handful of calls early Thursday reporting minor booms, but nothing on the scale of the
No injuries have been reported although some residents said they could feel the ground roll beneath their feet.
City officials say they have investigated every possible human cause. They checked water, sewer and gas lines, contacted the military about any exercises in the area, reviewed permits for mining explosives and inspected a dam next to City Hall. They even tested methane levels at the landfill in case the gas was spontaneously exploding.
Some folks said they were considering leaving town until investigators can determine the source.
"My husband thought it was cool, but I don't think so. This is not a joke," said Jolene Van Beek, who awoke early Sunday to a loud boom that shook her house. "I don't know what it is, but I just want it to stop."
Van Beek took her three sons to her father's home, 10 minutes away, so they could get some uninterrupted sleep.
About 300 people attended a public meeting Wednesday night in a local high school auditorium to get an update on the situation. Kuss assured residents that officials are doing everything they can to determine the source of the booming.
A Menlo Park seismologist has been called in to help solve an X-File in a Wisconsin town.
Residents of Clintonville, Wisconsin have been trying to get the bottom of some unexplainable noises in the night.
According to the Milwaukee Journal Sentinal, residents have compared the noises to such things as "a 90-ton wrecking ball slamming into something," to "fireworks exploding underwater."
One resident thought someone drove a car into her home, while another thought there were "critters" in her basement.
The noises woke up residents on the northeast side of Clintonville around 2 a.m. Monday and continued on and off until at least 8 p.m. the paper reports.
Authorities say the sounds are not earthquakes, methane gas, wastewater or military missions.
David Hill, a seismologist and scientist emeritus for the U.S. Geological Survey in Melo Park was called for his opinion.
"In North Carolina there are sand dunes and there's such a thing as booming sands," Hill said, "Of course, booming sounds travel a long ways. Sometimes thunderstorms can be beyond the horizon, but it's not likely that's the source of the noises in Wisconsin at this time of year."
Wisconsin sonic booms: Is a 1.5-magnitude jiggle the whole story?
The US Geological Survey suggests a small quake under Clintonville, Wis., and associated micro-tremors, could be the source of the mysterious sonic booms. Not everyone buys that.
By Mark Guarino, Staff writer / March 23, 2012
A resident ask questions at a public meeting with city officials at Clintonville High School in Clintonville, Wis., Wednesday. Sleepless families in a small Wisconsin town longed for quiet Wednesday after mysterious booming noises over the past few nights roused them from bed and sent residents into the street — sometimes still in pajamas.
After more than a week of strange sounds and sensations – the residents of “normally quiet” Clintonville, Wisconsin hope to get more answers.
They have already been stunned to learn that a 1.5 magnitude earthquake caused at least some of the vibrations, but they continue.
A team of scientists is preparing to install seismometers in the community 40 miles west of Green Bay.
The delicate devices register “shifts” in the earth.
WUWM Environmental Reporter Susan Bence spoke with a few of the experts hoping to narrow down the location and source of the continuing seismic activity.
Greg Waite is on the road when I reach him.
He figures the trip from his lab in Michigan to Clintonville will take about four hours.
He is less sure what is causing the seismic activity in the small Wisconsin town.
It’s not that Waite doesn’t know his earthquakes.
The Michigan Tech assistant professor of geophysics spends most of his time studying them.
“Well actually most of my work is in other countries, in Central America and South America, I study volcanic seismicity mostly,” Waite says.
Something as small as Clintonville’s 1.5 “rumbling” would normally be a blip on a monitor, but Waite’s interest was piqued by the continuing “swarm” of seismic activity.
“It’s so rare to have earthquakes in the upper Midwest,” Waite says.
Waite will not only monitor ground vibration, he’s hoping special microphones will pick up the low frequency sounds residents are reporting – the creaks, cracks and rumbles.
“It’s rare that there are good recordings of those sounds, so I thought it would be a good opportunity to try to collect good data to get a better of that phenomenon,” Waite says.
Everything Waite’s equipment detects will be funneled to U.S. Geological Survey scientists in Golden, Colorado. Dr. Harley Benz is shipping is “cell modums” to Clintonville, to link Waite’s system with the Colorado facility.
“It’s kind of a fancy cell phone in that it’s always on and it’s always transmitting data. So it connects to cell towers and so we can take data straight out of these seismograph stations. And if people feel something or hear something, we can look at the data immediately and figure out what it might have been,” Benz says.
Benz echoes Greg Waite’s words - that a quake as small as Clintonville’s would normally go unnoticed, but the mystery of what is happening there, is worth investigating.
“We can learning something from this exercise; to understand how the earth works. In places where earthquakes are rare; you know, the central and eastern U.S. have earthquakes but they’re more infrequent than, say in the western U.S. So we can learn something scientifically from this about the earthquake process. The other thing is people are concerned and rattled, and no pun intended. These things are waking them up; we don’t know what they are and we have technologies that might help to address this and so the state is asking for help and we have an obligation to help,” Benz says.
Another scientist – much closer to Clintonville – is also tuned into the case.
Steve Dutch teaches geoscience at the University of Wisconsin - Green Bay.
“We could conceivably have an unmapped fault below Clintonville. We have no information really about what’s under the surface there and stresses in the crust could be causing it to slip,” Dutch says.
Dutch plans to test his own theories. He suspects the quakes and strange noises might be related to the town’s groundwater levels.
“Apparently the ground water table is very low there right now and if you remove water from underground it removes some of the support for the rocks; and if the rocks settle they could creek and slip a little bit,” Dutch says.
As scientists ruminate and set up equipment, Lisa Kuss looks forward to easing residents’ anxiety.
She’s Clintonville’s city administrator.
“Night after night after night you’re being woken up with your house sounding like something’s exploding, that something hit your house, that you can’t sleep because it jars your whole house. That phenomenon, no matter what it’s being caused from, is disruptive to people’s lives,” Kuss says.
Kuss says it’s HER job to assure 4600 residents that Clintonville is a safe place to call home.

....................end update...................................... UPDATE: 3-23-2012 As you have probably heard by now, authorities have tamed the masses in Wisconsin with an explanation that defies science for the area. They say that there has been a swarm of shallow and small earthquakes that have rattled the area and that is where the phenomenon is coming from.
Hmmm...something is not quite right about that area.
First, it is on a bed of granite and is not proned to any earthquake of any kind.
THERE IS ONLY ONE EARTHQUAKE THAT SHOWS UP ON THE USGS SITE...
49 km (30 miles) NW of Appleton, Wisconsin
60 km (37 miles) WNW of Green Bay, Wisconsin
65 km (40 miles) E of Stevens Point, Wisconsin
181 km (112 miles) NNE of MADISON, Wisconsin
Secondly, these noises and the rattling is only happening at night. Their explanation? Things aren't as loud at night and people are more relaxed and therefore they would notice these things more.
Thirdly, skyquakes would make the noise and would cause the rattling without showing up on a seismograph in most cases. We have just had a large amount of solar activity that has really pressured our magnetosphere and the underlying ionosphere. Perhaps these noises are the magnetism pulling on the core, or from the magnetosphere and ionosphere attempting to pull back into place.
As scientists have announced (subtly) the Earth's core is destabilizing and most of the skyquakes are being created by this process. Perhaps the authorities in Wisconsin should use scientists in these other fields to come to a more likely conclusion than the one they used to tame the panic so that they would actually know what is happening there.
Here is an article with what they claim is happening in Wisconsin. What do you think?
Authorities solve the mystery of town's odd noises, shaking
From Jim Spellman, CNN
updated 12:22 PM EDT, Fri March 23, 2012
The locations of the reported "booms" in Clintonville, Wisconsin.
Clintonville, Wisconsin (CNN) -- The mystery behind four days of unexplained shaking and odd sounds rattling Clintonville, Wisconsin, has been solved.
The cause? A "swarm" of minor earthquakes amplified by the unique bedrock beneath the state of Wisconsin.
The strange sounds -- variously described as rattling pipes, clanging metal, thunder or firecrackers -- have continued on and off since early Sunday night in just one part of the small town of 4,600, located about 180 miles northeast of Madison. They were loud enough Monday morning that a CNN journalist could hear them during a cell phone conversation with city administrator Lisa Kuss.
Speaking to Clintonville residents Thursday night, Kuss said the U.S. Geological Survey has determined that "our community did in fact experience an earthquake that registered 1.5 on the earthquake magnitude scale." That minor quake was measured on Tuesday night by several mobile earthquake monitoring stations that were dispatched to the region, she said..
Based on all the data, the USGS believes the shaking and strange sounds are the result of "a swarm of several small earthquakes in a very short amount of time," Kuss said.
While these small earthquakes normally don't cause such commotion, Kuss said the location of the shallow temblors helped amplify the shaking.
"In other places in the United States, a 1.5 earthquake would not be felt," she said. "But the type of rock that Wisconsin has transmits seismic energy very well."
When the shaking began last Sunday, hundreds of residents began calling 911. Kerry Danley said she hear noises around midnight that sounded like a paintball gun.
"It was just pop-pop-pop," she said. "So I woke up -- just jumped out of bed actually -- ran downstairs, looked outside, nothing.
Since Sunday, the shaking has happened nearly every night, quieting down during the day. Absent of any explanations, residents were left to their own devices to come up with explanations.
"My bet is on gremlins," one Facebook user jokingly posted to WLUK's Facebook page. Alien machinery buried for millennia, countered another.
No, said one one tongue-in-cheek Twitter user. It's clearly mole men launching their attack on the surface dwellers.
Others suggested huge earthworms or sewer cats. Some Clintonville residents were even holding "shake" parties at night, waiting for the rumbling.
As city officials ruled out electrical explosions, gas leaks and sewer collapses, they started consulting geological experts around the country. Based on the data from eight seismic monitoring stations, Kuss said the USGS finally determined on Thursday that earthquakes were to blame.
While the cause of the shaking has been solved, it's still not clear if the rattling in Clintonville is over, Kuss said.
"There is no way to say for certain whether our area will ever again experience an earthquake," she said. "But it still very likely, although not guaranteed, that any future earthquakes that we experience would again be on the low end of the earthquake magnitude scale."
---------------------END UPDATE------------------------- As we have all heard by now, Wisconsin residents are experiencing some strange noise phenomenon. One explanation for this may be the destabilization of the Earth's core, which is causing a phenomenon called "skyquakes".
The following is information regarding the Wisconsin phenomenon and correlating explanation. Please remember that I am posting information found on the Internet. I cannot vouch or verify all of the information is accurate because it is from the Internet. However, from the research I have been doing, the "skyquake" phenomenon is definitely a plausible scenario in this particular case.
Here you go...

Vibration, Booming Sounds Reported In Clintonville
City Officials: Residents Started Reporting Sounds Early Monday MorningUpdated: 6:38 pm CDT March 19, 2012
CLINTONVILLE, Wis. -- The mysterious booming noises heard in Clintonville apparently have stopped -- for now.
Officials in that the city 40 miles west of Green Bay said there have been no additional reports of unusual activity since about 1:30 p.m. Monday.
Shortly before 2 a.m., residents flooded the Clintonville Police Dispatch with calls reporting explosions, rattling, vibrations and homes shaking. About 150 calls were received between 1:45 a.m. and 11 a.m.
The city contacted geologists from the University of Wisconsin-Madison, but says the noises and vibrations felt in Clintonville were not typical of earthquake activity.
Sounds Reported In Clintonville UPDATED Wednesday, March 21, 2012 --- 11:55 a.m.
CLINTONVILLE, Wis. (AP) -- Officials in an eastern Wisconsin city are trying to record a series of mysterious booming sounds that have roused residents from bed in the past few days, but their attempts have so far come up empty.
The city of Clintonville set up audio and video recorders overnight Wednesday but didn't capture anything. There was at least one loud boom at 5 a.m.
City administrator Lisa Kuss says most theories involving manmade causes have been ruled out. She says the city is planning to bring in some sort of vibration-detection devices to try to determine where the epicenter is.
The booms started Sunday. Residents describe them as sounding like thunder, fireworks or someone slamming a heavy door.
The city will hold a meeting Wednesday evening to update residents on the investigation.

Police dispatcher Tabitha Schoen says it was a quiet night in Clintonville until shortly after 5 a.m. when about 20 calls came in from residents who felt and heard the booms.
The booms, which have been compared to rumbles of thunder, sonic booms or fireworks, rattled homes and awakened some residents Sunday and Monday nights.
Authorities are at a loss to explain.
Seismologists have recorded unusual ground shaking in the area, similar to that caused by quarrying, mining and heavy truck traffic. But the city has ruled out such activities as possible sources of the disturbance.
A meeting about the mysterious noise is scheduled Wednesday night at the high school in Clintonville.

Mysterious Booms Wake Wisconsin Residents Up For Third Straight Day
Forget worrying about the wake up call of a rooster, residents in the Wisconsin city of Clintonville were woken up for the second time this week by the sound of a mysterious “boom.” The third time that such a noise has been heard in as many days.
The loud yet to be discovered noise was first heard in the early morning hours of Sunday and then again on Monday night.At this time authorities are not quite sure what has caused the “boom” noise. According to one city administrator:
“It startled everyone. They thought something had hit their house or a tree fell on their roof.” City officials tried to pool together their collective brainpower to come up with an explanation but so far they’ve been unable to pinpoint the location of the noise.
Clintonville residents in the meantime believe that the sounds are coming from underground which has led city workers to check and then recheck methane levels at local landfills, water pipes, sewer pipes and gas lines.
Officials even went so far as to contact the military to make sure they were not performing any type of military exercise in the area.
After all of those attempts turned up nothing they reviewed mining explosive permits and even checked the Pigeon River damn which is located next to city hall.
A local seismic station near the city has reported unusual seismic activity which is usually due to quarrying, mining or heavy truck traffic however the city ruled out those sources as the cause of the loud boom.
A public meeting for the citizens of Clintonville will be held on Wednesday night to discuss the unexplained activity. Read more at inquisitr.com

Mysterious Rumble Shakes Waushara County
by Marcie Kobriger What was it that shook residents in rural Waushara County out of their sleep Wednesday morning?
"I've never experienced anything like that in my life. It was strange, scary," Kevin White said. Residents near the Town of Leon say they felt the ground shake and heard a strange noise. Even the town chairman.
"We were doing chores this morning in the barn about 4:30, and all of a sudden everything shook, rumbled, and the cows jumped a little bit and kind of looked around, and then my brother and I both heard a noise," Chris Sorenson said.
Anna Syke was in the middle of a good night's sleep when something woke her. "I was sound asleep, 4:20 in the morning, and suddenly I wake up and the house is shaking. The best you can describe it as you would experience in an earthquake."
She was expecting the worst while fearing it was all in her head.
"Nothing came on the news. I called a sheriff's department employee that I'm friends with and he had no information, and then a neighbor called me at 5:30 and confirmed exactly what I felt."
The call was from White, who felt and heard the same thing about a mile away. He woke up because his cabin was shaking like a freight train.
"First I thought, 'Am I having a dream?' but I can't be having a dream. I thought it was an earthquake. I never experienced an earthquake, but that's what I thought an earthquake would be like," White said.
He said it sounded like thunder but was a constant rumble moving from south to north, and he could feel it through the cement slab. A minute-and-a-half later, it happened again.
White called the sheriff's department, which told him it received similar calls from other people and that it was investigating.
Given no explanation, White decided to take a look for himself.
"What it got light at 7 o'clock, I went and hopped on the snowmobie to see if I could find anything out in the woods, and I couldn't find anything out of the ordinary."
"There's a big block of 300 acres to the east of me that something could have crashed in there and you may not find it for quite a while," White offered.
"Did something crash? Did something explode? We have a lot of cabins out by us that are unoccupied, so that was going through our mind," said Syke.
The sheriff's department tells Action 2 News its deputies searched the area for a cause, like a plane crash, but came up with nothing.
The National Geological Survey and utility providers had nothing to report, either.
Which leaves those who felt and heard the rumblings to wonder what woke them.
"I've never had this happen to me in my life, and it's kind of scary when your whole foundation is shaking. You kind of want to know what's, what's going on, you know? It's unexplained," said White.
"Any answers we can get, because we're all just completely baffled, everyone who lives out here, and I think a little bit shook up -- literally, figuratively!" Syke said.
WISCONSIN - JULY 24, 2008 - A couple claims a mysterious noise plagues their house in Green Bay. The noise has been plaguing them for two years and sounds something like a rumbling motor, with a subtle vibration that won't quit. Then it stops - especially when they try to show city officials or acoustic experts what they're hearing. "It's like there's a semi parked right outside with the engine running, but when you look out, there isn't one." The couple have lived in the same house for 42 years. The problem only developed over the last two years.When they leave, the don't hear the noise, so they know it's not some health problem the two share. City officials hired a company for $1,000 worth of testing in the house this spring, but the tester came up with no noise and no significant vibration. The local alderman has heard the sound. "It's like an engine thing, a low-frequency vibration. I think it would be an annoyance." The immediate neighbors haven't complained, although some people have said they heard the sound.

Uploaded by ST3PRODUCTIONS on Jan 21, 20122012 Strange sounds heard worldwide explained Earth Hum -Strange Moaning Sounds Around The World are Skyquakes: Warnings From Earth's Destabilizing Core
Harmonics may signal massive Earth core slippage -- every 13000 years (when we cross the galactic equator?) the earth recieves a galactic wave that distrupts it's balance.
For those that think it is a HOAX or need a formal news report , here it is -- search on YT - "Mainstream Reporting Strange Noises Heard Around The World - Jan 26, 2012" - then come back and watch this video so it can all sink in again.
What is happening is the liquid iron core of the Earth is spinning at a different rate than the planet's rotation and the slippage is causing a measurable migration of the Earth's magnetic field. http://www.amazon.com/Dying-Her-Love-Diary-ebook/dp/B00381ALMK/ref=cm_cr_pr_p...
Earth's magnetic field in state of uncontrollable flux The skyquakes are caused by harmonics deep inside the Earth traveling from a mutating core through the layers of the planet to the surface. The sky acts as a sounding board capturing and magnifying the sonic and electrical frequencies shot from the center of the world.
Life depends on Earth's core. Something's happening to it.
Death and destruction on an Apocalyptic scale
The stresses building up in the core deep in the heart of the world also migrate outwards to the mantel and eventually the crust. Slipping strata within the bowels of the planet create incredible pressures...pressures so great that temperatures soar and dense metals flow like liquids. [See Doomsday: Earth's core spinning out of control]
Water becomes a superheated plasma and interacts with layers of quartz crystals emitting harmonics audible as a hum and also generating earth lights and skyquakes echoing across the sky . [See: Underground lightning may cause earthquake and volcanic events]

"Spacequakes" Discovered in Earth's Upper Atmosphere
Ker Thanfor National Geographic News Published July 30, 2010
The sun can dump enough energy into Earth's magnetic field to trigger "spacequakes" in our planet's upper atmosphere, a new study has found.
The space weather phenomenon—technically a strong vibration in the planet's magnetic field—can affect auroras and can spawn "space twisters" capable of bringing down power lines. (Related: "Aurora 'Power Surges' Triggered by Magnetic Explosions.")
In general, Earth's magnetic field lines can be thought of as rubber bands stretched taut by the solar wind, which is actually charged particles flowing in all directions from the sun, said study co-author Vassilis Angelopoulos, a space physicist at the University of California, Los Angeles. Earth's magnetic tail is the part of the field that's stretched out like a windsock by the sun's steady bombardment.
New data from a suite of NASA satellites called THEMIS (Time History of Events and Macroscale Interactions during Substorms) show that, when a magnetic field line in the tail builds up too much energy, it snaps, and part of the line is sent hurtling back toward Earth. In the process, the broken line can attract high-energy particles in Earth's atmosphere to create a whip-like "plasma jet."
These jets crash into other parts of Earth's magnetic field at about 20,000 miles (32,000 kilometers) above the planet's surface, where they bounce like tennis balls hitting a carpet. "We have learned that the plasma jets from the magnetic tail bounce and then bounce again, and so on, till they eventually lose all their energy," said Angelopoulos, also the principal investigator for THEMIS.
Each set of plasma jet impacts can release as much energy in total as a magnitude 5 to 6 earthquake, THEMIS revealed.
Spacequakes Spawn Magnetic Twisters
In addition, the impacts set Earth's entire magnetic field vibrating, and they create highly magnetic vortices, or space twisters, that penetrate down into the planet's atmosphere. (Related: "Earth's Magnetic Field Hisses Due to Distant 'Chorus'")
These vortices twirl Earth's magnetic field lines in the North and South Poles, where they can create bright ripples and whirls in auroras.
The effects of the vortices can even be felt on the ground, as they can induce current spikes in electrical lines that can bring down power grids over large areas.
(Related: "Magnetic Twisters 'Dance' Across Mercury, Study Says.")
By watching for spacequakes at polar monitoring stations—or even by looking at the visible effects in auroras—scientists can tell that major spacequakes happen about once a year, Angelopoulos said.
Smaller ones happen about once every four hours, he added, so "we have plenty of opportunities to study them."
The spacequakes study appears in the April issue of the journal Geophysical Research Letters. SOURCE: NATIONAL GEOGRAPHIC

SCIENTIST: “SOUNDS OF THE APOCALYPSE” ARE REAL PHENOMENA!
Posted by D.E. Paine on Thursday, February 9, 2012
RENOWNED GEOPHYSICIST SAYS STRANGE SKY SOUNDS ARE REAL Dr. Elchin Khalilov, a geophysicist and a professor in Azerbaijan [map], has been conducting research into the recent wave of strange sky sounds.
Dr. Khalilov refers to the phenomena as “sky hum.” As a geophysicist, he has become intrigued by the numerous reports and recording of the sky sounds. While others in the research community might be inclined to dismiss the whole thing as nonsense, Dr. Khalilov has been working with other researchers to explain what might be causing it.
In a recent article at GeoChange Journal (geochangemag.org), Dr. Khalilov responded to some questions about the sky hum phenomena.
MR. KHALILOV, WHAT IS THE NATURE OF THE UNUSUAL VERY LOW-PITCHED SOUNDS REPORTED BY A GREAT NUMBER OF PEOPLE IN DIFFERENT PARTS OF THE PLANET SINCE THE SUMMER OF 2011? MANY CALL THEM “THE SOUND OF THE APOCALYPSE”. INFORMATION ABOUT THAT COMES FROM ALL OVER THE WORLD: US, UK, COSTA RICA, RUSSIA, CZECH REPUBLIC, AUSTRALIA, ETC.
Dr. Elchin Khalilo “We have analyzed records of these sounds and found that most of their spectrum lies within the infrasound range, i.e. is not audible to humans. What people hear is only a small fraction of the actual power of these sounds. They are low-frequency acoustic emissions in the range between 20 and 100 Hz modulated by ultra-low infrasonic waves from 0.1 to 15 Hz. In geophysics, they are called acoustic-gravity waves; they are formed in the upper atmosphere, at the atmosphere-ionosphere boundary in particular. There can be quite a lot of causes why those waves are generated: earthquakes, volcanic eruptions, hurricanes, storms, tsunamis, etc. However, the scale of the observed humming sound in terms of both the area covered and its power far exceeds those that can be generated by the above-mentioned phenomena.”
IN THAT CASE, WHAT COULD BE CAUSING THIS HUMMING IN THE SKY? “In our opinion, the source of such powerful and immense manifestation of acoustic-gravity waves must be very large-scale energy processes. These processes include powerful solar flares and huge energy flows generated by them, rushing towards Earth’s surface and destabilizing the magnetosphere, ionosphere and upper atmosphere. Thus, the effects of powerful solar flares: the impact of shock waves in the solar wind, streams of corpuscles and bursts of electromagnetic radiation are the main causes of generation of acoustic-gravitation waves following increased solar activity.
“Given the surge in solar activity as manifested itself in the higher number and energy of solar flares since mid-2011, we can assume that there is a high probability of impact of the substantial increase in solar activity on the generation of the unusual humming coming from the sky. It should be pointed out that solar activity began to rise sharply since early 2011, with its amplitude significantly higher than all forecasts given by a number of influential scientific institutions in 2010 and 2011. Meanwhile, the observed increase in solar activity is fully consistent with the forecast of the International Committee GEOCHANGE published in the Committee’s Report in June 2010. If this growth rate of solar activity continues, its amplitude by the end of 2012 will be higher than the amplitude of 23rd solar cycle, and in 2013-2014 the solar activity will reach its peak the amplitude of which was predicted by us to be 1.5 – 1.7 times higher than the amplitude of the 23rd cycle.”
BUT YOU SAID THAT THE CAUSE OF THE “SKY HUM” CAN LIE WITHIN EARTH’S CORE AS WELL, WHAT DOES IT MEAN?
“There is one more possible cause of these sounds and it may lie at the Earth’s core. The fact is that the acceleration of the drift of the Earth’s north magnetic pole which increased more than fivefold between 1998 and 2003 and is at the same level today points to intensification of energy processes in the Earth’s core, since it is processes in the inner and outer core that form the Earth’s geomagnetic field. Meanwhile, as we have already reported, on November 15, 2011 all ATROPATENA geophysical stations which record three-dimensional variations of the Earth’s gravitational field almost simultaneously registered a powerful gravitational impulse. The stations are deployed in Istanbul, Kiev, Baku, Islamabad and Yogyakarta, with the first and last one being separated by a distance of about 10,000 km. Such a phenomenon is only possible if the source of this emanation is at the Earth’s core level. That huge energy release from the Earth’s core at the end of the last year was some kind of a start signal indicating the transition of the Earth’s internal energy into a new active phase.
“Intensification of the energy processes in the Earth’s core can modulate the geomagnetic field which, through a chain of physical processes at the ionosphere – atmosphere boundary level, generates acoustic-gravity waves the audible range of which has been heard by people in the form of a frightening low-frequency sound in different parts of our planet.
“In both cases, even though the causes of acoustic-gravity waves are of a quite understandable geophysical nature, they are indicative of the expected significant increase in solar activity and the geodynamic activity of our planet. There is no doubt that processes in the core rule the internal energy of our planet, therefore, we should expect by the end of 2012 a sharp rise in strong earthquakes, volcanic eruptions, tsunamis and extreme weather events with peak levels in 2013 – 2014.”
