Six earthquakes rattle Oklahoma in 18 hours, geologists say

Six earthquakes in 18 hours rumbled in Oklahoma, the latest in ongoing seismic activity across the state, geologists say.

Another two quakes just across the border in Kansas also hit in the past day, according to the U.S. Geological Survey.

The first of the six earthquakes in Oklahoma began Sunday with a 2.4-magnitude quake near Quinton, a small town about 150 miles east of Oklahoma City. The others includes one near Stroud, two east of Waukomis, another in Guthrie and the last east of Buffalo shortly after 7 a.m. Monday.

They ranged in intensity from magnitude between 1.3 to 2.8. About 20 people reported feeling the 2.8-magnitude earthquake near Guthrie, according to the U.S. Geological Survey. Few, if any, felt the other quakes.

In Kansas, a 2.4 magnitude quake hit south of Cheney about 11:25 p.m. Sunday. Another earthquake of the same magnitude rumbled about 12:40 p.m. southwest of Medicine Lodge.

Just last week, seven earthquakes in 24 hours rumbled in Oklahoma, ranging from magnitude 1.6 to 2.5. In early March, another eight earthquakes hit the state in less than a day.

While aftershocks are quakes after a large earthquake on a fault, a swarm is a series of smaller earthquakes that occur in the same locations, according to the U.S. Geological Survey.
