Okla. sees huge uptick in 2013 earthquakes

OKLAHOMA CITY — Oklahoma recorded 222 earthquakes with magnitudes of 2.5 or greater last year, soaring above 2012’s total of 64 such temblors, according to seismologists studying the source of the recent uptick in quakes.

This year is already off to a seismologically busy start — the state has recorded 63 earthquakes at 2.5-magnitude or greater during 2014, according to The Oklahoman. That total doesn’t include several earthquakes that struck Logan County late Sunday and early Monday.

“The more earthquakes you are going to have, the more damaging earthquakes you are going to have,” said seismologist Austin Holland with the Oklahoma Geological Survey. Holland said there were 97 quakes at 2.5-magnitude or greater in 2011, and 104 such quakes in 2010.

Scientists are not sure why seismic activity has spiked.

“We’re continuing to try to understand this and to keep up with the number of earthquakes,” Holland said.

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.
