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.




7.4 Magnitude (possibly two back-to-back) Hits South of the Figi Islands. No Destructive Tsunami Detected.

  6. 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".

More Mysterious Booms Without Explanation & Startling Residents


Spreading? Mysterious tremors rattle homes in South Jersey

March 21, 2013 – SOUTHERN NEW JERSEY - Just after 3 o’clock Tuesday afternoon residents in Atlantic, Cape May, and Cumberland counties say they felt multiple earthquake-like tremors that rattled their homes and offices. Absecon resident, Kay Stadlmeir, said, “I don’t think it would be an earthquake, but what could it be? It’s just really odd.” Somers Point resident, Bob Mower, explained, “There was a rattling of my windows and I felt the house shake just a little bit – it was unusual.” Stadlmeir told NBC40, “It has to be something really big to be witnessed in such a widespread area of South Jersey.” The reports vary from region to region. Atlantic county emergency management officials confirmed with the U.S. Geological Survey that it was not an earthquake. The next thought was that military training or an aircraft flying by might have caused the shakes. Both the 177th Fighter Wing in Egg Harbor Township and Joint Base McGuire-Dix-Lakehurst confirmed none of their aircrafts were in the area at that time. Joint Base McGuire-Dix-Lakehurst is still working to confirm whether or not any ground training was happening at the time, although it is unlikely that would cause such a widespread shake. Stadlmeir said, “I really don’t think it’s a sonic boom because, you know as I said before, I’ve experienced them before and this is nothing like that.” Mower told NBC40, “That was real unusual. I almost wondered if I was dreaming on that one.” After initial reports of the shakes came in, NBC40 put the word out on Facebook to see who else felt it. Immediately we received hundreds of responses from all over South Jersey. Concerned Egg Harbor Township resident, Oliana Collado, said, “I just think it’s weird because some people didn’t feel it and it’s like in random spots, and it’s very spread out. Yeah it was scary, but I’m just glad it wasn’t worse than what it was.” When we reached out to New Jersey State Police Headquarters, we were told that our call marked the first time they had heard about possible tremors and they were unable to tell us anything further. NBC40 will continue to investigate the cause of these mysterious tremors. –NBC40

Unexplained boom baffles experts, residents

NOISE HEARD IN SEVERAL COUNTIES MAY GO UNSOLVED
March 19, 2013 1:00 am  •  
The mystery of the “loud boom” heard in parts of the region over the weekend may go unsolved as efforts to find the source of the boom proved a bust Monday.
Hundreds of people in at least four counties — Franklin, Hamilton, Saline and Williamson — flocked to social media to report hearing a windows-rattling, earth-shaking boom between 1 and 2 p.m. Saturday.
No damages or injuries were reported as a result of the boom.
“I have no way of knowing exactly what occurred but it was not likely an earthquake,” geophysicist Don Blakeman of the National Earthquake Information Center said. “There is nothing on our lists, only the last one on the 11th (near Benton).”
Some earthquakes are heard as well as felt, he said, but if it was so widespread as to be heard in four counties, “We would be able to locate it as an earthquake,” he said. “Typically, when loud booms are heard it turns out to be a sonic boom, although I’m not saying that’s what it was in this instance.”
However, if the boom was sonic in nature, it wasn’t caused by military action. Neither Scott Air Force Base nor the North American Aerospace Defense Command reported activity taking place in the region Saturday.
“We were not in that area with any of our assets,” a NORAD spokesman said.
A Scott Air Force spokeswoman confirmed no Scott or military-related activities or exercises took place in Southern Illinois over the weekend.
The boom was not weather-related, according to meteorologist Robin Smith of the National Weather Service in Paducah said.
Nor was it related to any coal mining activity, a spokeswoman for the Illinois Office of Mines and Minerals said.
The swarm of social media postings caused Franklin County Emergency Management Agency Director Ryan Buckingham to make his own post on the agency’s Facebook page.
“Residents in Franklin County are reporting what was described as a ‘ground-shaking loud boom’ during the day on Saturday 3/16/2013. USGS (U.S. Geological Survey) has not reported any earthquake activity in our area during that time, leaving the cause of these reports as somewhat of a mystery,” Buckingham wrote.
The mystery was not cleared up by Monday, he said.
“We picked it up first on social media. A lot of people heard it but didn’t have a source for it,” Buckingham said. “I put a feeler out on Facebook because if there is a threat to public safety, that’s something we need to know about it, but no one had any idea what caused it.”
While the source of the boom has yet to be traced, Buckingham said it should serve as a reminder for residents to have a plan in place in case of emergency.

Does Uptick in Mysterious "Booms" Foretell Mega-Quake?

Brandon Turbeville
Activist Post

Back in October, I wrote an article entitled “Numerous Reports of Mysterious Booms and Strange Lights Over South Carolina,” in which I described the sounds and vibrations heard and felt all across the Pee Dee region of South Carolina with some witnesses even describing strange lights in the sky at the time of the event.

These strange occurrences were eerily similar to those described by individuals all across the state of Michigan like Bob Powell of The Truth Is Viral, who was actually detained as a result of attempting to investigate the nature of these sounds and vibrations. Please see my article, “Investigation Continues Into Source of Strange Michigan Area ‘Explosions’ and Radiation Spikes” for a further description of what took place in Michigan.

Similar noises and vibrations were also felt in New Jersey around October, as I wrote in my article “New Mysterious 'Booms' Reported in New Jersey.”

But while the incidents in Michigan and New Jersey were researched from a distance, it just so happens that this writer was in the Pee Dee region of South Carolina when the two “mysterious booms” in the first article took place. At the time, I described the incidents as follows:

[The incidents] spann[ed] the entire Pee Dee region and all the way into North Carolina. On the evening of November 5, around 7:30-7:45 p.m., various law enforcement and local news agencies were contacted by individuals living in the Pee Dee region of South Carolina in reference to a loud “boom” that was large enough to shake their houses.


The reports were numerous around Pamplico, Johnsonville, Marion, Hemingway, Aynor, Nichols, Hannah, and Mullins. However, as stated earlier, reports also came from as far away as Evergreen, North Carolina.

Marion County dispatchers alone received more than 100 calls in ten minutes related to the “booms.”


The US Geological Society has publicly stated that there was no seismic activity in the region on these dates and emergency dispatchers confirmed that there had been no plane crash.


Very soon after the event, Johnsonville Police Chief, Ron Douglas, claimed the “booms” were “from a handful of military aircraft” that had broken the speed of sound.
However, this explanation, which was rapidly adopted by the local media, does not hold water. For one thing, most of the individuals I have spoken to (as well as myself) have heard jets break the sound barrier before and both the sound and the impact of the mysterious “booms” were much different than that of jets breaking the sound barrier.


Secondly, if the jets were the cause of the sound and of the heavy vibrational impact that shook so many houses, the jets themselves would have had to be flying very low. But, if the jets were flying low enough for this type of effect to be achieved, witnesses would have also been able to hear the jets.


This writer can personally attest to the intensity of the “booms” as I, myself, was in the area at the time of the incident. The sound, much like what Bob Powell described sounded much more like artillery than any other comparable sound. There was no lead up to the shaking, it was simply as if one was experiencing the vibrations of an explosion.


The impact was so strong that one way to describe hearing and feeling the impact from inside the house, it would be if one could imagine a full grown adult climbing on top of the back of a couch or recliner and leaping off, landing full force on the living room floor. Much like this scenario, the impact was sudden and short-lived.
The sound, however, was extremely similar to the firing of artillery, much as Powell described it in Michigan.

The above incident occurred, as mentioned earlier, on November 5. However, one week prior, a similar, albeit weaker, explosion was heard in the same locations. Reports were made to this writer from both Marion and Mullins in terms of the noticeable impacts and sounds of this separate explosion. Like the first, the sound was similar to artillery, the impact was also distinct but sudden and brief.


To my knowledge, there have been no mainstream local reports of the earlier “explosion.” Also as in the second incident, I can personally attest to the nature of the first. 
 
After the initial curiosity surrounding the incidents subsided, news coverage and local talk expectedly subsided as well. Yet, on January 6, 2013, South Carolina residents again began hearing these booms and feeling the vibrations powerful enough to “rattle windows.” This time, the location was not the Pee Dee region but in the Red Bank area of Lexington County. Interestingly enough, around the same time period (between January 2- 6 2013), these “booms” were heard and felt in other locations across the country including in Alaska, Oklahoma, Massachusetts, and Indiana.

The Pee Dee region was not to be overlooked, however, as on March 2, 2013, more reports were published regarding booms and vibrations powerful enough to shake houses. As with the other instances of booms and vibrations, there was no seismological activity in the area at the time. [1]
However, since the first set of occurrences in the Pee Dee region, two individuals have been paying special notice to the incidents of the mysterious booms, detailing and recording the dates of their occurrence as felt in the Conway/Myrtle Beach area.

Skyquakes? Earthquakes? Explosions? Pole Shift? Unexplained Booms All Over The Globe.







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.

















Mysterious 'booms' still unexplained

Booms
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.
On Tiverton-Little Compton Patch's Facebook page, residents as far away as Portsmouth also reported feeling the mysterious mid-evening boom.
"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.
