4.7 Magnitude Earthquake Rattles Oklahoma

A 4.7 magnitude earthquake struck Oklahoma Thursday morning around 1:42 a.m. It was centered in Alfalfa County and Cherokee, Oklahoma.

It was felt as far east as Tulsa. There have been no reports of any injury or damage.

2.5 to 3.0 magnitude earthquakes are usually the smallest quakes felt by humans. 4.0 earthquakes can cause damage.

Last Wednesday, state officials said Oklahoma is now the top earthquake prone area in the world. The U.S. Geological Survey blames fracking for the frequency of earthquakes in the Sooner State.
