4 Northern California faults primed for big earthquakes
October 13, 2014

california earthquake faults

Three fault segments running beneath Northern California and its roughly 15 million people are overdue for a major earthquake, including one section that lies near the dams and canals that supply much of the state's water, according to a geological study published Monday.

The three fault segments and one other in the region are loaded with enough tension to produce quakes of magnitude 6.8 or greater, according to a geological study published Monday.

They include the little-known Green Valley fault, which lies near key dams and aqueducts northeast of San Francisco. Underestimated by geologists until now, the fault running between the cities of Napa and Fairfield is primed for a magnitude-7.1 quake, according to researchers from the U.S. Geological Survey and San Francisco State University.

 
USGS: Risk of earthquake increased for half of USA
July 18, 2014

 A new federal earthquake map dials up the shaking hazard just a bit for about half of the United States and lowers it for nearly a quarter of the nation.

The U.S. Geologic Survey updated Thursday its national seismic hazard maps for the first time since 2008, taking into account research from the devastating 2011 earthquake and tsunami off the Japanese coast and the surprise 2011 Virginia temblor.

Most of the changes are slight. Project chief Mark Petersen said parts of Washington, Oregon, Utah, Oklahoma, Colorado, Wyoming and Tennessee moved into the top two hazard zones.

Parts of 16 states have the highest risk for earthquakes: Alaska, Hawaii, California, Oregon, Washington, Nevada, Utah, Idaho, Montana, Wyoming, Missouri, Arkansas, Tennessee, Illinois, Kentucky and South Carolina.

Tsunami Warning Issued After 8.0 Magnitude Quake Near Alaska
June 23, 2014
8.0 Alaska Quake 6-23-2014

 A tsunami warning has been issued for parts of Alaska after a magnitude 8.0 earthquake was recorded off of Little Sitkin Island.

Tsunami.gov has issued a warning for coastal areas of Alaska, warning that “significant inundation is possible or is already occurring.” Residents of the area were being warned to move inland, or to higher ground.

The quake was originally recorded as an 7.1 but was quickly upgraded to a 8.0. according to the USGS, in a change from the usual pattern where quakes are downgraded.  An 8.0 quake is exponentially stronger.

The extreme depth of the quake at over 70 miles deep prevented a more widespread Pacific-wide tsunami.

The Pacific Tsunami Warning Center does warn that some coastal areas in Alaska and the Northwest may experience “non-destructive sea level changes” for several hours.

The earthquake was reported at 11:53 a.m. local time.

 
Author Claims Earthquakes Predictable, Says Next Big Ones This Summer...
May 31, 2014
They are pretty rare in our area, but every few years the Pittsburgh area will feel an earthquake that will shake the ground enough to give us a scare. Mainstream science says that earthquakes cannot be predicted, but David Nabhan author of “Earthquake Prediction: Answers in Plain Slight” says otherwise.

Nabhan is a former teacher in California and now lives in Pittsburgh. He became interested in earthquakes while he was the earthquake preparedness coordinator for the school he worked at. He says he noticed every earthquake happened at dusk or dawn.

“I realized this sort of conscience doesn’t happen in science. These dawn and dusk quakes during new and full moons are the paradigm on the west coast,” he said. “All six great quakes that have struck in Los Angeles that have killed people since the 30s, all of them, dawn or dusk [quakes].

How can earthquakes be predicted? Nabhan says that it is the, “conjoined lunar and solar gravitational tides,” are what cause them.

Bay Area could face cluster of deadly earthquakes
May 19, 2014
San Francisco Bay from space

California's San Francisco Bay Area grew into a metropolis during the eerily quiet earthquake gap following its devastating 1906 temblor. Scientists predict a 63 percent chance of another big quake before 2032, but when the shaking starts, it may not be a single "Big One" as in 1906, according to a new study.

Instead, the Bay Area could face a cluster of deadly earthquakes that deliver a series of rapid punches, researchers report today (May 19) in the Bulletin of the Seismological Society of America.

The report is another nail in the coffin for the idea that earthquake faults repeat their behaviors in the same way every time. "The historical record is not sacrosanct," said lead study author David Schwartz, a geologist with the U.S. Geological Survey (USGS). "It's really clear that the frequency of different earthquake sizes varies over time."

A team of scientists is exploring the darkest corners of a huge underwater volcano in the Caribbean in hopes of better understanding the mysteries of earthquakes and tsunamis, ultimately saving lives. Kick'em Jenny is a dangerous and active volcano sitting roughly 6,000 feet below the surface of the Caribbean Sea, and located off the coast of the island of Grenada, south of St. Lucia. Robert Ballard, famous for discovering the Titanic 12,000 feet below the surface of the icy North Atlantic in 1985, set his sights on exploring the Kick'em Jenny to study its eruption history and learn more about how underwater volcanoes can pose a threat.

 
Rare Earthquake Warning Issued for Oklahoma
May 05, 2014

Mile for mile, there are almost as many earthquakes rattling Oklahoma as California this year. This major increase in seismic shaking led to a rare earthquake warning today (May 5) from the U.S. Geological Survey and the Oklahoma Geological Survey.

In a joint statement, the agencies said the risk of a damaging earthquake — one larger than magnitude 5.0 — has significantly increased in central Oklahoma.

Geologists don't know when or where the state's next big earthquake will strike, nor will they put a number on the increased risk. "We haven't seen this before in Oklahoma, so we had some concerns about putting a specific number on the chances of it," Robert Williams, a research geophysicist with the USGS Earthquake Hazards Program in Golden, Colorado, told Live Science. "But we know from other cases around the world that if you have an increasing number of small earthquakes, the chances of a larger one will go up."
 
Magnitude-7.2 earthquake shakes Mexican capital
April 18, 2014

A powerful magnitude-7.2 earthquake shook central and southern Mexico on Friday, sending panicked people into the streets. Some walls cracked and fell, but there were no reports of major damage or casualties.

The U.S. Geological Survey said the quake at about 9:30 a.m. (10:30 a.m. EDT; 1430 GMT) was centered on a long-dormant fault line northwest of the Pacific resort of Acapulco, where many Mexicans are vacationing for the Easter holiday.

It was felt across at least a half-dozen states and Mexico's capital, where it collapsed several walls and left larges cracks in some facades. Debris covered sidewalks around the city.

 
How Bad Would A Yellowstone Eruption Be?
April 03, 2014

Mount St. Helens was tiny compared to the most dangerous category of volcano – the super volcano. The Yellowstone super volcano is located in the Yellowstone National Park of Wyoming. Try to imagine a volcanic eruption 10,000 times stronger than Mount St. Helens – an eruption that would threaten our very survival.

8.2 MAG QUAKE STRIKES NORTHERN CHILE
April 01, 2014

A powerful magnitude-8.0 earthquake struck in off Chile's northern coast Tuesday night, and authorities ordered an evacuation of coastal areas in case of a tsunami. There were no immediate reports of injuries or damage.

The U.S. Geological Survey said the quake struck 61 miles (99 kilometers) northwest of the city of Iquique at 8:46 p.m., shaking a region that has been rocked by numerous quakes over the past two weeks.

The latest tremor also shook buildings in parts of the nearby nations of Bolivia and Peru. Waves measuring almost 2 meters (6 1/2 feet) already were striking cities on the northern coast.

 
Tsunami warning: Magnitude 8.0 quake strikes off Chile

Chile earthquake tsunami disaster 2014

A tsunami warning has issued an expanded regional tsunami warning for Chile, Peru and Ecuador after a major magnitude 8.0 earthquake stuck off the coast of Chile.

A tsunami watch is also in effect for Colombia, Panama and Costa Rica.

The quake hit near the mining area of Iquique, the U.S. Geological Survey said.

It says the quake was very shallow, only 10 km below the seabed, which would have made it feel stronger. It was centred 86 km northwest of Iquique.

More to follow.

7.5 quake on California fault could be disastrous
March 31, 2014
california earthquake disaster

Experts say a bigger earthquake along the lesser-known fault that gave Southern California a moderate shake could do more damage to the region than the long-dreaded "Big One" from the more famous San Andreas Fault.

The Puente Hills thrust fault, which brought Friday night's magnitude-5.1 quake centered in La Habra and well over 100 aftershocks by Sunday, stretches from northern Orange County under downtown Los Angeles into Hollywood - a heavily populated swath of the Los Angeles area.

A magnitude-7.5 earthquake along that fault could prove more catastrophic than one along the San Andreas, which runs along the outskirts of metropolitan Southern California, seismologists said.

 
Is California overdue for a big earthquake?
March 29, 2014
california big one earthquake overdue

On March 17, a mild earthquake rattled countless Los Angeles-area residents awake shortly before their alarms went off at 6:30 a.m. The Monday morning temblor was the first notable L.A.-area quake in years.

A lengthy vacation from earthquakes certainly sounds nice. But John Dvorak, a geophysicist who now works at a astronomical observatory in Hawaii, warns that a quake break can just be the calm before the earthquake storm.

He makes his case that the Golden State is in for trouble in his readable and aptly named new book "Earthquake Storms: The Fascinating History and Volatile Future of the San Andreas Fault." But it's not just Californians who should pay attention to his exploration of earthquake science, the unfolding mysteries of geology, and the gaps in our seismic knowledge. As he notes in an interview, plenty of other parts of the country are vulnerable to earthquakes, including the Northwest, the Midwest, the South and – yes – even the Big Apple.

 
Video: Are We Facing A Super Volcano Eruption?
February 27, 2014
super volcano
I have been been trying to come to grips with this because of the weird weather and most of all, the strange earthquake activity in places that don’t normally experience it. One of our dedicated supporters shared this video with us and we felt it was definitely worth sharing with everyone.

While this video is a compilation of others, they all carry the same theme; Yellowstone. We are not trying to create panic or play into some conspiracy theory, we want people to be alert and prepared. Is the USGS hiding something? Does the government know about it and they are making plans? We actually spoke with an employee at Yellowstone National Park via Twitter and they dismissed everything as “faulty” equipment. But only a few weeks later did the southeastern portion of the United States experience an earthquake. Coincidence?

You watch these videos and you decide for yourself. Hopefully it will still be on here before it is removed by the powers that be.

 
US storm 'Hercules' brings 27ft waves to Land's End and flood sirens in Dorset

US storm hercules waves 2014

More flooding is expected across the country today and tomorrow as the west coast counted its losses following the arrival of "Winter Storm Hercules", the system which has left behind a record-breaking deep freeze in the US.

Waves have been recorded as high as 27ft at Land's End, and reports on surfing forecast websites suggested scores of professional "big wave chasers" had followed Hercules' movements across the Atlantic.

Last night a flood siren warning of extreme danger to people and property was sounded in Dorset, as gales and tidal surges battered the coast.

 
Volcanoes: Nature's ticking time bombs
January 06, 2014
If you think we're living in an unstable world, just listen to this: only one percent of our Earth is solid rock. Most of the other 99 percent is an oozing, mass, churning beneath our feet like road tar at temperatures between 2,000 and 10,000 degrees. The Earth's crust is only 20 miles thick. When that cracks, one of the greatest forces in nature erupts. There are 1,500 active volcanoes. And, tonight, we want to tell you about three; one that caused the most recent mass disruption, another that's the biggest threat to a major city and a third, in the United States that could wreak havoc all around the world.

Supervolcanoes Erupt by Their Own Rules
January 06, 2014
supervolcanoes erupt
Huge volcanic blasts occur less frequently than scientists would expect, and now volcanologists think they can explain why: super-eruptions and smaller eruptions are triggered by fundamentally different processes.

Small volcanoes, such as Italy’s Stromboli, erupt when molten rock rises from deep within Earth and then stalls in an underground chamber until enough pressure builds to blast it out to the surface. But the magma chambers of giant volcanoes—such as the one that erupted 2 million years ago beneath what is now Yellowstone National Park in the western U.S.—are too large for pressure from magma squirts to cause an eruption.

Instead, the molten rock accumulates until its sheer buoyancy creates a different kind of stress, one that cracks open the top of the chamber and starts an eruption, researchers report.
 
Risk of supervolcano eruption big enough to 'affect the world' far greater than thought
January 06, 2014
The eruption of a “supervolcano” hundreds of times more powerful than conventional volcanoes – with the potential to wipe out civilisation as we know it – is more likely than previously thought, a study has found.

An analysis of the molten rock within the dormant supervolcano beneath Yellowstone National Park in the United States has revealed that an eruption is possible without any external trigger, scientists said.

Scientists previously believed many supervolcanic eruptions needed earthquakes to break open the Earth’s crust so magma could escape. But new research suggests that this can happen as a result of the build-up of pressure.

Supervolcanoes represent the second most globally cataclysmic event – next to an asteroid strike – and they have been responsible in the past for mass extinctions, long-term changes to the climate and shorter-term “volcanic winters” caused  by volcanic ash cutting out the sunlight.

 
Beneath Yellowstone, a volcano that could wipe out U.S.
December 14, 2013
Yellowstone National Park Supervolcano

It’s the awe-inspiring pride of the United States – and it harbors a deadly power that could kill us all.

Yellowstone National Park is pristine wilderness, full of scenic landscape and iconic hot-pools and geysers that attract tens of thousands of visitors every year.

But it’s what lies beneath that has scientists scurrying.

We’ve long known that Yellowstone is merely the skin on top of a supervolcano – a giant pool of magma sitting just under the Earth’s surface. Exactly how giant has been the subject of much speculation... Until now...

 
Expert : ‘Imagine America Without Los Angeles’
December 12, 2013
WEST COAST EARTHQUAKE DISASTER
A leading earthquake expert has issued a dire warning to Californians about the expected impact of a major disruption to the San Andreas fault line. The title of Dr. Lucy Jones’ lecture this week to the American Geophysical Union in San Francisco was titled “Imagine America without Los Angeles.”

As KCAL9′s Dave Bryan reports, Jones, a Science Advisor for Risk Reduction at the U.S. Geological Survey, says when the “Big One” hits Southern California, the damage could be much greater, and could last much longer, than most of us ever imagined.

“Loss of shelter, loss of schools, loss of jobs and emotional hardship. We are risking the ends of our cities,” she said during the presentation. According to a USGS study called the “Shakeout Report,” when a high-magnitude earthquake rocks the San Andreas fault, the damage will go far beyond the collapsed buildings and freeways seen in the 1994 Northridge earthquake.

 
Seven Volcanoes In Six Different Countries All Start Erupting Within Hours Of Each Other
November 21, 2013
seven volcanoes six countries erupt

A new island has appeared in the Pacific. A submarine eruption just off Nishino-Shima Island Japan has erupted for the first time in 40 years. The Japanese Navy noticed the explosions as boiling lava met sea water giving rise to plumes of steam and ash.

Almost 7,000 miles away in Mexico, the Colima volcano blew its top after a period of relative calm. A steam and ash cloud rose two miles into the sky and the grumbling of the mountain could be heard in towns a few miles away. In Guatemala the ‘Fire Mountain’ belched out lava and sent up a moderate ash cloud causing an ash fall over nearby towns. The explosions and shock waves occurring in the volcano can be felt by residents over 6 miles away. Doors and windows are reported to be rattling, but there has been no damage so far.
 
What Caused the Deadly Midwestern Tornado Outbreak?
November 19, 2013
midwest tornado outbreak

A slew of tornadoes slammed the state of Illinois and surrounding areas yesterday (Nov. 17), killing six people and damaging or destroying thousands of homes, according to news reports. Eighty-one tornado reports were submitted to the National Weather Service (NWS) yesterday, most of them in the Land of Lincoln, though more than one report could be for the same tornado.

The devastation was significant enough that Gov. Pat Quinn declared seven counties state disaster areas, including Tazewell County, where a twister left parts of the town of Washington in ruins. One of the tornadoes in this area was preliminarily declared an EF-4, the second strongest type of tornado, said Illinois state climatologist Jim Angel. These twisters pack winds between 166 to 200 mph (267 to 322 km/h) and are strong enough to destroy sturdy houses and hurl cars. [LIVESCIENCE]

 
How Typhoon Haiyan Compares to the 2004 Tsunami
November 12, 2013
Haiyan super typhoon 2013 damage
Super Typhoon Haiyan ravaged the central Philippines on Friday (Nov. 8), affecting millions and displacing hundreds of thousands.

The tropical cyclone (the blanket term for hurricanes and typhoons) packed sustained winds of up 190 mph (305 km/h) in the hours before it made landfall, according to some accounts. It will likely go down as one of the five strongest storms in the last 50 years, even though estimates of the storm's strength vary, said Brian McNoldy, a tropical storm expert at the University of Miami. Estimates vary because there were no airplanes in the area to drop recording instruments into the storm (the typical way of making such measurements). Jeff Weber, a researcher at the University Corporation for Atmospheric Research in Boulder, Colo., put Haiyan in the top three strongest storms, as measured by wind speed at landfall. Some compared the storm's devastation to the mayhem caused by the 2004 Indian Ocean tsunami, which resulted from a magnitude-9.1 earthquake that struck west of the island of Sumatra on Dec. 26 of that year.
 
Official: Super Typhoon Death Toll Could Reach 1,200
November 09, 2013
super typhoon death toll

In the wake of once-Super Typhoon Haiyan (local name Yolanda), the death toll is estimated to rise to 1,200 across the Philippines. “We estimate 1,000 people were killed in Tacloban and 200 in Samar province,” Gwendolyn Pang, secretary general of the Philippine Red Cross, said in a report by CNN.

Tacloban was “ground-zero” for Haiyan’s devastation, stated AccuWeather.com Meteorologist Eric Wanenchak. There is more bad news for the Philippines as a tropical disturbance, perhaps becoming a tropical storm, will reach the nation during the middle of next week. [LINK]
