Series of small earthquakes rock Oklahoma in record seismic activity

Series of small earthquakes rock Oklahoma in record seismic activity

(Reuters) – Earthquakes rattled residents in Oklahoma on Saturday, the latest in a series that have put the state on track for record quake activity this year, which some seismologists say may be tied to oil and gas exploration. One earthquake recorded at 3.8 magnitude by the U.S. Geological Survey rocked houses in several communities around central Oklahoma at 7:42… Read more →

Yellowstone Volcano Eruption in 2014? Are Animals Fleeing Park As ‘An Alert’?

This map from the U.S. Geological Service shows the range of the volcanic ash that was deposited after the biggest of the Yellowstone National Park eruptions around 2.1 million years ago. "These eruptions left behind huge volcanic depressions called “calderas” and spread volcanic ash over large parts of North America," it said. "If another large caldera-forming eruption were to occur at Yellowstone, its effects would be worldwide. Thick ash deposits would bury vast areas of the United States, and injection of huge volumes of volcanic gases into the atmosphere could drastically affect global climate. Fortunately, the Yellowstone volcanic system shows no signs that it is headed toward such an eruption in the near future. In fact, the probability of any such event occurring at Yellowstone within the next few thousand years is exceedingly low."

A number of bloggers are posting videos that show bison and other animals allegedly leaving Yellowstone National Park, prompting theories that as earthquakes ramp up the seismic activity will set off the Yellowstone supervolcano.

Two of the main bloggers behind the discussion stress that there’s no way to know when the supervolcano will go off but note that the 4.8 magnitude earthquake that hit on March 30 seemed to set off a reaction from the animals, who are moving for a reason.

“Whether I believe this, or whether I don’t believe the story or not, I don’t know. I can tell you this story I saw this morning about the buffaloes running the street … whether or not it’s because of any activity in Yellowstone or not, I don’t know,” said blogger Jay Lee, who posted a story on his site tatoott1009.com.

“But I’ll tell you this, whatever the case may be, that their running away from Yellowstone is an alert of some sort.”

Powerful 8.2-magnitude earthquake off Chile kills at least 5, forces evacuations

A powerful magnitude-8.2 earthquake struck in the Pacific off Chile’s northern region on Tuesday, killing at least five people, causing landslides and setting off a small tsunami, leading authorities to order an evacuation.

Interior Minister Rodrigo Penailillo attributed the five deaths to heart attacks or being crushed. In the city of Arica, the mayor reported some minor injuries and said some homes made of adobe were destroyed.

About 300 inmates escaped from a women’s prison in the city of Iquique, and officials said Chile’s military was sending a planeload of special forces to guard against looting.

The quake shook modern buildings in nearby Peru and in Bolivia’s high altitude capital of La Paz.

“We have asked citizens to evacuate the entire coast … there is no serious damage to houses … there have been no people hurt,” said home office minister Mahmud Aleuy, Reuters reported.

The U.S. Geological Survey initially reported the quake at 8.0, but later upgraded the magnitude. It said the quake struck 61 miles northwest of the Chilean city of Iquique at 8:46 p.m., hitting a region that has been rocked by numerous quakes over the past two weeks.

Report: Some Bay Area Communities Could Run Out Of Water Within 4 Months

SAN JOSE (KCBS) — As the drought in California continues, 17 communities throughout the state could run out of water within 60 to 120 days, state officials said. In some districts, the wells are running dry while other reservoirs are nearly empty. The state Health Department compiled a list after surveying the more than 3,000 water agencies in California last… Read more →

California Drought: Higher Food Prices, Fewer Jobs, Less Power

California’s severe drought could have wide-ranging effects beyond familiar water restrictions, ranging from higher food prices to a power shortage in the state. The Fresno Bee reports that farmers in parts of California are leaving fields to lie fallow, bulldozing fruit trees and selling cattle stocks prematurely–all of which could add up to higher food prices around the country if production… Read more →

Supervolcano eruption mystery solved

Supervolcano eruption mystery solved

Scientists have made a breakthrough in their efforts to understand what causes so-called supervolcanoes to erupt. Supervolcanoes are capable of eruptions thousands of times larger than normal outpourings. It was thought that an external trigger, such as an earthquake, was needed to bring about a giant blast. But tests at the European Synchrotron Radiation Facility in Grenoble show the sheer… Read more →

‘Imagine America Without Los Angeles’: Expert Warns Southern California Isn’t Ready For Major Quake

LOS ANGELES (CBSLA.com) — 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 “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.

Yellowstone: The Super-Volcano that Could Blow up America

A super-volcano under Yellowstone National Park in Wyoming is an even bigger threat to the US than previously thought, scientists have found. Researchers from the University of Utah said the volcano’s magma chamber – a lake of molten rock beneath the National Park - is approximately 2.5 times bigger than earlier estimates suggested. If the volcano were to erupt today, scientists predict that… Read more →

Italian authorities have declared a state of emergency in Sardinia after a cyclone struck the Mediterranean island.

At least 16 people are known to have died and hundreds have been moved from their homes after winds of up to 125 kilometres an hour and sheets of rain brought devastation.
Several people are reported missing.

In the northeastern town of Olbia, the mayor said sudden flooding had burst “like a bomb”. The skies dumped as much rain in an hour as falls on Milan in six months, Gianni Giovanelli added.
