TULSA - The U.S. Geological Survey is reporting that the Saturday night temblor in Oklahoma was the strongest ever recorded in the state.
According to USGS , the earthquake that struck at 10:53 p.m. Saturday was upgraded to a magnitude 5.6 after early calculations listed it as a 5.2. The epicenter is four miles east of Sparks in Lincoln County, 21 miles northeast of Shawnee.
Lincoln County Emergency Management reported significant damage in the southern parts of the county. In some cases chimneys have collapsed through the roofs of homes. Air conditioning ducts collapsed through the ceiling at the Prague library.
Several roadways have buckled, including Highway 62 near County Road 3470 and other county roads. The road was closed for an hour for crews to repair the cracked pavement.
The Oklahoma Department of Transportation has been surveying bridges 50 miles from the epicenter.
There has been no word on any injuries reported.
At St. Gregory's University in Shawnee, one tower collapsed and three others were badly damaged and are in danger of falling, said university officials. A hole in the building's roof has been covered pending further repairs.
The USGS reported that tremors were felt in most of Oklahoma as well as eastern and central Kansas, most of Missouri and Arkansas, north Texas and southeast Nebraska.
Minor damage was reported after a 4.8 magniture earthquake occurred in the early morning hours Saturday near Prague, Okla.
Aftershocks were felt for hours following Saturday's first quake, which Amie Gibson, a research scientist for the Oklahoma Geological Survey, said was the strongest to hit the state in nearly sixty years.
That is, until this most recent quake.
Gibson said Saturday that aftershocks from the first earthquake could occur for days.
Saturday night's earthquake broke the state's record set in 1952 in El Reno. That quake was recorded as a 5.5.
