STILLWATER, Okla. — The U.S. Geological Survey gave a preliminary measurement of a 4.2 magnitude for an earthquake that shook 15 kilometers northeast of Perry after 10 p.m. Monday.

There were multiple reports of the earthquake having been felt in Tulsa and Oklahoma City. Some have reported feeling it in Wichita, Kansas. It was measured at a depth of 3.3km. 

In the last two months, Oklahoma has only experienced a few earthquakes measuring over 3.5M. Hennessey had a 4.1 on Oct. 31, Edmond experienced a 3.7 on Nov. 19 and Perry had a 3.7 on Nov. 8.

If Monday's measurement holds, it will be the largest earthquake in Oklahoma since a 4.3 shook Medford on Sept. 8.
