Small earthquake recorded in Yale, Okla.;study shows more than 200 have hit state since 2009
1:11 PM, Oct 27, 2013
Earthquake swarms continue to hit central Oklahoma almost two years after a record 5.6 magnitude quake rattled the state.
The latest was recorded near Yale, Okla. by the U.S. Geological Survey. The USGS says the 2.5 magnitude quake was recorded at 2:20 a.m. Sunday two miles southwest of Yale, about 60 miles northeast of Oklahoma City.
Geologists say earthquakes of magnitude 2.5 to 3.0 are general the smallest that are felt by humans and that damage is not generally seen from quakes below magnitude. 4.0.
A new report by the U.S. and Oklahoma geological surveys says more than 200 quakes of magnitude 3 or greater have hit the state since January 2009.
Experts say there is a growing amount of evidence indicating they may be linked to injection wells used in hydraulic fracking to get at natural gas.
