Oklahoma City, OK – Central Oklahoma residents felt the ground move twice in less than 24 hours this week, after two small earthquakes were recorded near the Oklahoma City metro area.
According to the Oklahoma Geological Survey, the first quake, a magnitude 2.8, struck Thursday, Sept. 18, at 2:02 p.m. local time about 2 kilometers northeast of Minco in Grady County. It was recorded at a depth of 7.4 kilometers. At least 18 residents submitted “Did You Feel It?” reports, with light shaking noted in parts of the region.
The second earthquake followed the next morning, Friday, Sept. 19, at 8:27 a.m. local time. This event measured magnitude 2.5 and occurred 9 kilometers east-northeast of Calumet, in Canadian County. Preliminary data show it was shallow, with a depth of just 0.3 kilometers. No felt reports were submitted for this quake as of Friday afternoon.
While both quakes were considered minor, they add to Oklahoma’s history of seismic activity, much of which has been linked in past years to underground wastewater injection. Officials have not tied these latest tremors to any specific cause.
Residents are encouraged to report their experiences on the USGS “Did You Feel It?” platform, which helps scientists better understand the reach and intensity of local earthquakes.
No injuries or damage were reported in either event.
