TULSA - Three early morning earthquakes shook Oklahoma Monday, the biggest a 4.2-magnitude that struck about 9 miles southeast of Edmond at 5:47 a.m.
A number of Green Country residents reported feeling that temblor, which interrupted the 2NEWS Today newscast and meteorologist George Flickinger's weather forecast. See that video above.
A 3.5 quake hit the same area at 5:31 a.m., according to the USGS, and a 3.0 was recorded at 6:25 a.m.
Officials with the Oklahoma Department of Transportation tell 2NEWS crews check structures for damage after quakes stronger than a 4.0. After inspections Monday, no damage was found.
Three more small earthquakes hit in northcentral Oklahoma over the weekend. The USGS recorded a 3.2-magnitude quake at 5:55 p.m. Saturday 18 miles west-southwest of Tonkawa. The quake had a depth of 2.4 miles.
The area is near where two more earthquakes were recorded Sunday. A 3.0-magnitude quake was recorded shortly before 9 a.m. 7 miles west-northwest of Medford. It had a depth of 3.3 miles.
Another 3.0-magnitude temblor was recorded at 12:30 p.m. Sunday 5 miles east of Medford. It had a depth of 3.1 miles.
Geologists say quakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and damage isn't likely in quakes below magnitude 4.0.
