USGS Warns Oklahoma Of Growing Quake Chances

(Reston, VA) The United States Geological Survey has issued an earthquake warning for Oklahoma saying chances of an earthquake in central Oklahoma of 5.5 or greater has greatly increased.

The USGS reports earthquakes in Oklahoma have increased by about 50 percent since October 2013, “significantly increasing the chance for a damaging quake in central Oklahoma.”

The U.S. Geological Survey and Oklahoma Geological Survey reported 183 earthquakes of magnitude 3.0 or greater happened in Oklahoma from October 2013 through April 14, 2014.

“This compares with a long-term average from 1978 to 2008 of only two magnitude 3.0 or larger earthquakes per year. As a result of the increased number of small and moderate shocks, the likelihood of future, damaging earthquakes has increased for central and north-central Oklahoma.”

“While it’s been known for decades that Oklahoma is ‘earthquake country’, we hope that this new advisory of increased hazard will become a crucial consideration in earthquake preparedness for residents, schools and businesses in the area,” said Dr. Bill Leith, Senior Science Advisor for Earthquakes and Geologic Hazards at USGS. “Building owners and government officials should have a special concern for older, unreinforced brick structures, which are vulnerable to serious damage during sufficient shaking.”
