California Hit With Earthquake Of 6.0 Magnitude

Video: California hit with earthquake of 6.0 magnitude - August 24th, 2014 - Ellen Knickmeyer

A large earthquake rolled through California's northern Bay Area early Sunday, damaging some buildings, igniting fires, knocking out power to tens of thousands and sending residents running out of their homes in the darkness.

Two major injuries have been reported, and hospitals have been very busy with moderate injuries, Napa Division Fire Chief John Callanan said. The 6.0-magnitude quake caused six significant fires, including at four mobile homes, Napa Division Fire Chief Darren Drake said.


Ohio links fracking to earthquakes, announces tougher rules - April 11th, 2014 - Edward McAllister

Recent small earthquakes in Ohio were likely triggered by fracking, state regulators said on Friday, a new link that could have implications for oil and gas drilling in the Buckeye State and beyond.

In the strongest wording yet from the state linking energy drilling and quakes, the Ohio Department of Natural Resources (ODNR) said that injecting sand, water and chemicals deep underground to help release oil and gas may have produced tremors in Poland Township last month.

The statement, in which the department announced stricter rules for oil and gas exploration in areas where seismic activity has occurred, comes after a steep rise in earthquakes in Ohio and other areas where intense drilling has taken place.


Ohio Officials Tight-Lipped on Fracking, Monday’s Earthquakes - by Will Drabold - March 12, 2014

While geologists raised questions yesterday about whether a northeastern Ohio fracking operation caused a series of earthquakes in Mahoning County on Monday, state officials refused to provide any answers.

On Monday, Ohio Department of Natural Resources officials ordered Texas-based Hilcorp Energy to shut down an active well at the Carbon Limestone Landfill near Lowellville after four temblors were recorded in the area.

“It’s an area which (before 2011) had no history of earthquakes,” said John Armbruster, a retired Columbia University geology professor who had worked with Ohio officials to monitor a recent series of earthquakes tied to a fracking-waste injection well near Youngstown.


USGS - 2011 Oklahoma Human-Induced Earthquake May Have Triggered Larger Quake

                                   - March 6, 2014

PASADENA, Calif. — In a new study involving researchers at the U.S. Geological Survey, scientists observed that a human-induced magnitude 5.0 earthquake near Prague, Oklahoma in November 2011 may have triggered the larger M5.7 earthquake less than a day later. This research suggests that the M5.7 quake was the largest human-caused earthquake associated with wastewater injection.

"The observation that a human-induced earthquake can trigger a cascade of earthquakes, including a larger one, has important implications for reducing the seismic risk from wastewater injection," said USGS seismologist and coauthor of the study Elizabeth Cochran.

Researchers Link Earthquakes In Texas To Fracking Process

Researchers at Southern Methodist University have linked a string of 2009 and 2010 earthquakes in Texas to the injection of fracking wastewater into the ground, according to a new study.

The researchers examined the group of more than 50 earthquakes that hit the area of Cleburne, Texas in 2009 and 2010, and found that they could have happened because of wastewater injection wells associated with fracking operations. Before 2008, the Fort Worth Basin of Texas had never experienced an earthquake.

Great Shakeout Earthquake Drills


submitted by Katie Cook

Many areas of the globe are prone to earthquakes. You could be anywhere when an earthquake strikes: at home, at work, at school or even on vacation. Are you prepared to survive and to recover quickly?

Great ShakeOut earthquake drills are an opportunity to practice how to be safer during earthquakes: "Drop, Cover and Hold On." ShakeOut also has been organized to encourage you, your community, your school, or your organization to update emergency plans and supplies, and to secure your space in order to prevent damage and injuries.


7 Ways the Response to a Devastating Earthquake Has Changed

Most San Francisco Bay Area residents over 30 years old remember exactly where they were at 5:04 p.m. on Oct. 17, 1989, when the magnitude 6.9 Loma Prieta earthquake shook the region.

I certainly do. I was just getting ready to drive home to Palo Alto, a few miles from the editorial offices of InfoWorld, a technology publication in Menlo Park, where I worked.

U.S. seismologists currently testing new warning system

by Andrew Pinsent - CBC News - May 5, 2012

Scientists in the United States have been testing an advanced tsunami warning system using GPS data, combined with traditional seismology networks, to attempt to detect the magnitude of an earthquake faster so warnings of potential tsunamis can get out to potentially affected areas sooner.

The prototype is called California Integrated Seismic Network (CISN), and is a collaboration between the United States Geological Survey (USGS) and The Gordon and Betty Moore Foundation, whose focus is on environmental conservation.

Transforming Earthquake Detection?

submitted by Linton Wells - January 20, 2012

Earthquakes are a collective experience. Citizens have long participated in earthquake science through the reporting, collection, and analysis of individual experiences. The value of citizen-generated status reports was clear after the 1995 Kobe, Japan, earthquake (1). Today's communications infrastructure has taken citizen engagement to a new level: Earthquake-related Twitter messages can outrun the shaking (2), Internet traffic detects earthquakes (37) and maps the distribution of shaking in minutes (810), and accelerometers in consumer electronic devices record seismic waveforms (1116). What are we learning from this flood of data, and what are the limitations? How do we harness these new capabilities for scientific discovery, and what is the role of education?


Invisibility Cloak to Protect Buildings from Earthquakes

Homeland Security News Wire - February 15, 2012

Scientists show that by cloaking components of structures with pressurized rubber, powerful waves such as those produced by an earthquake would not “see” the building — they would simply pass around the structure and thus prevent serious damage or destruction

University of Manchester mathematicians have developed the theory for a Harry Potter-style cloaking device which could protect buildings from earthquakes.

Dr. William Parnell’s team in the University’s School of Mathematics has been working on the theory of invisibility cloaks which, until recently, have been merely the subject of science fiction.

In recent times, however, scientists have been getting close to achieving cloaking in a variety of contexts. A University of Manchester release reports that the work from the team at Manchester focuses on the theory of cloaking devices which could eventually help to protect buildings and structures from vibrations and natural disasters such as earthquakes.
