A small earthquake has rocked the state of Oklahoma again. According to the U.S. Geological Survey, a 3.2 magnitude quake was recorded just before 6 a.m. on Sunday in Logan County. The quake’s center was 27 miles northeast of Oklahoma City. No injuries or damages have been reported.
On Saturday, a small 2.4 magnitude earthquake was recorded at 7a.m. near Sparks, which is 50 miles northeast of Oklahoma City.
The area has been rocked by six tremors since Thanksgiving Day. On Thursday, a 3.7 magnitude earthquake was recorded near Prague, with another 3 recorded on Friday.
A 5.6 magnitude tremor rocked Oklahoma on Nov. 5. It was the strongest ever recorded on the Richter scale in the state. The tremors were felt throughout the Midwest, including in Kansas, Missouri, Arkansas, Texas and Illinois.
Oklahoma has had 10 times more earthquakes than normal since mid-2009, Austin Holland, a research seismologist with the Oklahoma Geological Survey, told The New York Times.
“It could be a natural cycle; we just don’t know,” Holland said.
Oklahoma does not sit on top of a major fault line, which makes it unclear why more seismic activity has been recorded recently, sources said.
The last major earthquake to hit the state was a 5.5-magnitude quake that struck in 1952, according to officials.
