The weekend's earthquake swarm continues with 14 aftershocks recorded Sunday morning in Oklahoma. The latest aftershock was magnitude of 3.3 recorded at 12:26 p.m. located 10 miles northeast of Shawnee.

These following the strongest quake in the state's history - one with a magnitude of 5.6 -which rocked the stands at the Oklahoma State University game at 10:53 Saturday night.

It could be felt throughout the state and in Kansas, Missouri, Arkansas, northern Texas and some parts of Illinois and Wisconsin, said geophysicist Jessica Turner at the U.S. Geological Survey.

There were no reports in the hours after the quakes of any severe injuries or severe damage.

The quake jolted OSU's stadium shortly after the Number 3 Cowboys defeated Number 17 Kansas State.

"That shook up the place, had a lot of people nervous," Oklahoma State wide receiver Justin Blackman said of the late Saturday quake. 

"Yeah, it was pretty strong."

Since that time, 14 tremors measuring from 2.7 to 4.0 are listed on the U.S. Geological Survey. The most recent was a 3.3 magnitude earthquake located 10 miles northeast of Shawnee at 12:26 p.m. It was 37 miles east of Oklahoma City.

Researchers with the Oklahoma Geological Survey report that the earthquakes have occurred on the Wilzetta fault, also known as the Seminole uplift. They are now referring to Saturday morning's 4.7 magnitude earthquake as a foreshock.

First reports had Saturday night's quake listed as 5.2 magnitude.  It struck Oklahoma at 10:53 p.m. The epicenter was located four miles east of Sparks, eight miles south of Davenport, nine miles north northwest of Prague, and 45 miles east of Oklahoma City. The earthquake was only three miles deep.

The crowd of nearly 59,000 was still leaving Oklahoma State's Boone Pickens Stadium when the earthquake hit, and players were in the locker rooms beneath the stands. The shaking seemed to last the better part of a minute, rippling upward to the stadium press box.

"Everybody was looking around, and no one had any idea," Oklahoma State quarterback Brandon Weeden said.

"We thought the people above us were doing something. I've never felt one, so that was a first."

Callers to the News 9 and News On 6 newsrooms in Oklahoma City and Tulsa reported from all over Oklahoma about Saturday night's earthquake, including Oklahoma City, Tulsa, Ardmore, Noble, Hennessey, Yukon, Alva and more.

According to the Oklahoma County Sheriff's Office, there are no major reports of damages or injuries from the earthquake. However, News 9 is getting reports of structure damages out of Lincoln County, as well as reports of buckled roads near Prague.

According to the Lincoln County Emergency Management, there is a significant amount of damages in Lincoln County. Reports also showed that Main Street and Bell Avenue is blocked off in downtown Shawnee. Apparently, Neil's Furniture in Shawnee has suffered significant damages.

The new sites are very close to the magnitude 4.3 earthquake that took place February 27, 2010, according to the Oklahoma Geological Survey.
