Dataset at a glance — Oklahoma

Over the past 30 days, Oklahoma has recorded 4 earthquakes of magnitude 2.5 or greater in our tracker. The remaining 4 fell in the M2.5–M3.9 band. By depth: 4 shallow (<70 km). 3 of the epicenters were offshore. 2 events produced at least one felt report, totalling 144 citizen submissions to the USGS Did You Feel It? system. Focal depths ranged from 5.6 km to 17.5 km. All 4 solutions have been reviewed by a USGS seismologist.

Leading the list is a magnitude 3.5 event near 2 km ESE of Johnson, Oklahoma at 17.5 km depth, which drew 141 felt reports from the public. The second-ranked event, at magnitude 3.0 near 17 km SE of Waynoka, Oklahoma, trails by 0.5 magnitude units — a narrow gap, indicating two comparably energetic events in the current window. Rounding out the top three is a magnitude 2.7 earthquake near 4 km SE of Ratliff City, Oklahoma.
