Central Oklahoma reportedly shook by an earthquake at 12:10 pm CST Saturday, December 7, just weeks after the two-year anniversary of the strongest earthquake ever recorded in the Sooner state.

The U.S. Geological Survey (USGS) recorded a 4.5 magnitude earthquake which was centered near Arcadia about 7 miles east of Edmond, 14 miles northeast of Oklahoma City and was about 5 miles deep. The earthquake lasted for about 3 to 5 seconds and was said to be strong enough to wake someone from a nap.

Report says that the Oklahoma City area has seen a series of smaller earthquakes in recent months and the most severe was recorded early November with a 3.9-magnitude about 4 miles northwest of Jones. It was also noted that the seismic activity in Oklahoma had become more common in the last several years and scientists are not sure why earthquakes seismic activity had spiked.

The strongest earthquake recorded by the USGS in Oklahoma was a 5.6 magnitude earthquake on November 5, 2011 near the town of Prague which recorded 200 damaged buildings.

According to reports, scientist and researchers are continously studying the cause of sudden increase of the seismic activity in this region. Some suggest that the shaking could be related to wastewater disposal from oil and gas drilling operations of energy industries that rely on hydraulic fracturing, or “fracking.” However, they repeatedly insisted that such practice is safe. On the other hand, researchers said that it is not yet clear whether fracking can trigger significant quakes.

No injuries has been reported according to the Oklahoma Department of Emergency Management spokeswoman Keli Cain, but there are some minimal property damage that was noted.
