A magnitude 5.1 earthquake with an epicenter in Prague, Oklahoma just east of Oklahoma City was felt in Fayetteville and much of the rest of the region on Friday night, according to the US Geological Survey.
The earthquake happened at 11:24 p.m., and was followed by smaller earthquakes of magnitudes of 2.6 and 3.5 in the area.
The larger quake was felt in parts of southern Kansas and Missouri, north Texas, and much of western Arkansas.
From the USGC:
Earthquakes east of the Rocky Mountains, although less frequent than in the West, are typically felt over a much broader region than earthquakes of similar magnitude in the west. East of the Rockies, an earthquake can be felt over an area more than ten times larger than a similar magnitude earthquake on the west coast.
