The U.S. Geological Survey says it has awarded $2.7 million to four organizations to improve monitoring of the Earth's crust in earthquake-prone areas.

The awards, made under the American Recovery and Reinvestment Act, went to the University of California-Berkeley, Central Washington University, the University of California-San Diego and UNAVCO Inc. to improve networks that detect minute changes in the Earth's crust caused by faulting in earthquake-prone regions.

"Monitoring these small changes … is an integral part of assessing the likely rate of large earthquakes," the USGS said. "For optimal performance in real time, many existing monitoring stations need modern sensors and improved communication systems. Funds provided through six cooperative agreements will improve monitoring capabilities by replacing obsolete sensors that may be more than 10 years old and by upgrading communications so that real-time data streams are more reliable or possible for the first time."

Scientists Say Nothing Unusual About 2010 Quake Activity
Boulder CO (SPX) Apr 15, 2010
China's tragic magnitude 6.9 earthquake on April 13 and the recent devastating earthquakes in Haiti, Chile, Mexico, and elsewhere have many wondering if this earthquake activity is unusual. Scientists say 2010 is not showing signs of unusually high earthquake activity. Since 1900, an average of 16 magnitude 7 or greater earthquakes - the size that seismologists define as major - have occur ... read more
