Midsized earthquakes moved toward more populated areas of Oklahoma City yesterday, shaking an area that has been the focus of regulators.
OKLAHOMA CITY -- Gov. Mary Fallin (R) defended her administration's response to a string of earthquakes linked to oil and gas activity that have rattled the state, saying it could take more than a year for the policy to have an effect.
The earthquakes displayed were located in Oklahoma and occurred from Jan. 2, 2008, until Jan. 15, 2015, based on Oklahoma Geological Survey information. The earthquakes are a minimum 2.0 magnitude. Click map to link to animation. Map courtesy of USGS.
A surge in seismic activity is occurring around the U.S., and many top scientists are pointing at injection of waste from drilling and hydraulic fracturing as a possible culprit.
