Main story– At least four earthquakes shook parts of Oklahoma early Tuesday. A 4.3 magnitude earthquake occurred at 1:56 a.m. with an epicenter about 7 miles east, northeast of Luther and 22 miles east of Edmond, according to the U.S. Geological Survey. Rumblings were felt across a wide portion of central Oklahoma, but there were no immediate reports of damage. Austin Holland, a geophysicist at the Oklahoma Geological Survey in Norman, said he is gathering data about the quakes Tuesday. He said it is possible there were more than four quakes early Tuesday. “At this point it looks like a main shock, aftershock sequence. There are even a bunch of smaller ones,” Holland said.”
