A pair of earthquakes, just minutes apart, hit Oklahoma Monday afternoon, rattling the nerves of hundreds of thousands of people across at least five states in the middle of the work day. The first hit at 12:49 CDT near Crescent, Oklahoma, about 40 miles north of Oklahoma City. The second, more powerful earthquake came just 23 minutes later and was also centered near Crescent. The second tremor measured a preliminary 4.5-magnitude, according to the USGS. People across at least five states said they felt it: Oklahoma, Kansas, Texas, Missouri and Arkansas.

According to the USGS database, this is the strongest earthquake in the region since a magnitude-4.9 near Conway Springs, Kansas, on November 12, 2014. While there were no reports of major damage, the second tremor was shallow — less than 2 miles deep — and the reports of people who felt it were flowing into the USGS. People near the center in Crescent felt the strongest shaking, but the quake also startled people in Tulsa, Norman and downtown Oklahoma City.
