GUTHRIE — Several earthquakes, including a magnitude-4.1 quake, shook parts of central Oklahoma early Thursday, the U.S. Geological Survey reported.
The 4.1 quake was felt in parts of southern Logan and northern Oklahoma counties at 2:33 a.m. The epicenter was about six miles south-southwest of Guthrie, about a half mile north of W Forrest Hills Road.
Social media users in the area reported feeling the quake and being awakened by shaking and loud noises. One woman in south Edmond said the quake “knocked our power off and on for a bit.”
Austin Holland, seismologist for the Oklahoma Geological Survey in Norman, said the overnight earthquakes were part of the Liberty Lake swarm, which started Feb. 12. Residents have reported hearing booms and some have reported objects falling inside homes. The central Oklahoma earthquakes continue to be studied by scientists, he said.
“There are a lot of different earthquake sequences going on right now in Logan County,” Holland said.
Mark Sharpton is the Logan County commissioner for District No. 1, which includes the area where the quakes were reported. Sharpton said the largest earthquake of the night, the magnitude-4.1 quake, woke him up, and he was unable to get back to sleep afterward.
He said he looked at his Facebook account and found he was not alone.
“It looked like everyone in the district was up,” Sharpton said. “That one kind of rock-and-rolled us there for a while.”
Sharpton said he had heard no reports of damage.
The 4.1 quake was not the only one reported in the Logan County area. There were several smaller ones prior, and at least one significant aftershock.
At 3:19 a.m., a magnitude-3.7 quake was recorded seven miles south-southwest of Guthrie, just east of S Broadway Street.
Also, at 11:48 p.m. Wednesday, a magnitude-3.3 quake was reported 10 miles northeast of Perry, north of the Cimarron Turnpike in Noble County.
At 11:53 a.m. Thursday, a magnitude-3.1 quake shook 13 miles north-northeast of Stillwater. A second magnitude-3.7 quake struck the same area at 1 p.m.
