The 5.6-magnitude earthquake that hit Oklahoma at 10:53 p.m. EDT Saturday has caused significant damage to the southern parts of Lincoln County.

Kjrh.com reports that the air conditioning ducts of the Prague Library have broke through the ceiling.

The Lincoln County Emergency Management officials have reported that chimneys have crashed through the roofs of several homes. The crews are reported to be out assessing damage in the area.

Roads in the county have buckled and KJRH reports that Highway 62 near County Road 3470 has been affected, in addition to other county roads.

As of Sunday morning, only one minor injury has been reported. According to CNN.com, a man tripped and hit his head against a wall while trying to flee his home when the earthquake struck.

The Saturday evening earthquake is the largest to ever hit the state. Prior to this earthquake, the largest was a magnitude 5.5 quake that hit near El Reno, Okla., on April 9, 1952. The earthquake caused a 50-foot-long crack in the State Capitol Office Building in Oklahoma City.

While large earthquakes are not common in Oklahoma, according to a geological survey report of Oklahoma by Kenneth V. Luza, there have been more than 880 earthquakes in the Anadarko Basin between 1897 and 2002.

The Anadarko Basin is a geological feature that covers nearly 50,000 square miles. Most of the basin is located in the west-central part of Oklahoma.

Luza states that most of the earthquakes that occur in Oklahoma are not felt due to being of magnitudes of between 1.8 and 2.5. There have been earthquakes in 72 counties of Oklahoma. The only counties that have never reported an earthquake are Adair, Craig, Jackson, Nowata and Washington, according to Luza’s survey.

The survey includes a map of Oklahoma showing the major fault lines that run throughout the state. It also marks the locations of earthquakes reported between 1897 and 2002. The map shows a heavy concentration of earthquake epicenters in Grady, McClain and Garvin counties. These three counties are located nearly parallel to fault zone located within 25-37 miles of the counties.
