OKLAHOMA CITY (AP) — The United States Geological Survey says the rate of earthquakes in Oklahoma has increased by about 50 percent since October 2013, significantly increasing the chance for a damaging quake in central Oklahoma.

In a statement by the U.S. Geological Survey and Oklahoma Geological Survey, the agencies reported that 183 earthquakes of magnitude 3.0 or greater occurred from October 2013 through April 14. This compares with an average of only two magnitude 3.0 or larger earthquakes per year from 1978 to 2008.

A senior adviser from the USGS says he hopes the new advisory will become a crucial consideration in earthquake preparedness for residents, schools and businesses in the central Oklahoma area.

The statement indicates that a likely factor in the increase in earthquakes is wastewater injection.
