jonesjan15quakeOklahoma recorded 222 earthquakes with magnitudes of 2.5 or greater in 2013…a pretty impressive number for a “non-earthquake” state. In 2012 the state recorded a total of 64 temblors. An increase of 158!!!!  2014 is already off to a busy start – the state has recorded 63 earthquakes so far at 2.5-magnitude or greater.

The cause of the increase in seismic activity is under investigation. Seismologist Austin Holland with the Oklahoma Geological Survey says there were 97 quakes at 2.5-magnitude or greater in 2011, and 104 such quakes in 2010.

Oklahoma’s strongest recorded earthquake was a 5.6-magnitude quake that struck in November 2011 near Prague. It damaged 200 buildings, shook a football stadium and rattled parts of seven states.
