Oklahoma City, OK – USGS: 18 aftershocks following 5.6 quake in Okla.

SPARKS, Okla. (AP) The U.S. Geological Survey has recorded 18 aftershocks following a 5.6 magnitude earthquake that shook central Oklahoma.

The USGS says aftershocks ranging from a preliminary magnitude of 2.7 to 4.0 have been recorded in the same area near Prague, about 45 miles east of Oklahoma City.

Two aftershocks of magnitude 4.0 were recorded at 3:39 a.m. and 9:07 a.m. Sunday.

USGS seismologist Paul Earle in Golden, Colo., said the aftershocks will likely continue for several days and could continue for months.

The first aftershock was a magnitude 3.0 recorded at 11:54 p.m. Saturday one hour after the 5.6 magnitude quake toppled a tower at the St. Gregory's University campus in Shawnee.

There were no reports of injuries or additional damage from the aftershocks.
