California lawmakers approved bills yesterday dealing with hydraulic fracturing's effect on seismic activity and methane emissions.
Texas energy regulators will hold formal legal hearings to probe the link between natural gas development and a string of earthquakes that struck near the small town of Azle last year.
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.
