Update: 6-18-2012 Wisconsin Strange Noises Are Now An X-File. Now Booms and FLASHES.

UPDATE: 6-18-2012
-----------------------------END UPDATE----------------------------------------------------

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.
From the article here:
“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

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.
Baraboo's booms come weeks after residents of Clintonville -- 130 miles to the north -- began reporting mysterious booming and shaking which began March 19.

Clintonville, Wisconsin Booms: City Hires Firm To Explore Mysterious Noises

Clintonville Booms

First Posted: 03/22/2012 2:42 pm Updated: 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.

CA Scientist Comments On Weird Wisconsin Noises

Strange booms and bangs wake up residents in the middle of the night.

CA Scientist Comments on Weird Wisconsin Noises

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."
For now, the mystery continues

Wisconsin sonic booms: Is a 1.5-magnitude jiggle the whole story?

Scientists Step Up Efforts to Solve Clintonville

Susan Bence
WUWM NEWS | MAR 30, 2012

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.

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.

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

The locations of the reported

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.

Vibration, Booming Sounds Reported In Clintonville

City Officials: Residents Started Reporting Sounds Early Monday MorningUpdated: 6:38 pm CDT March 19, 2012 
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.

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.

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.

Booming sounds started up around 5 a.m.:

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.

Renowned Geophysicist Says Strange Sky Sounds Are Real

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. 
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.

"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.

Back in June/July 2008, during an unusually intense storm in Newcastle Emlyn, Wales (UK), I heard a very strange sound. Just after a huge clap of thunder, a noise was generated, seemingly from the sky, that sounded like a very low-frequency fog-horn. It had immense power behind it and the echo from the 2-3 second 'blast' could be heard clearly reverberating along the Teifi valley, way after the initial sound had stopped. Many people must have heard this, but I assume that as the sound was foghorn-like, it was never investigated. Reports of thumps, bumps and rumbles, as well as trumpet-like reports, buzzing and other unusual noises from the sky and ground - from all around the globe - have convinced me that the noise I heard back in 2008 is part of a related phenomena.
