Oklahoma City, Okla. – Residents west of Oklahoma City were shaken awake early Monday after two earthquakes struck within minutes of each other near Calumet. The stronger of the pair, a magnitude 3.3 quake, hit around 3:25 a.m., following a smaller 2.7 tremor just 10 minutes earlier.
According to the Oklahoma Geological Survey, both quakes were centered roughly 7 kilometers east-northeast of Calumet in Canadian County, at shallow depths of just over a kilometer. The larger quake generated community intensity reports rating it at level IV, meaning it was felt by several people indoors but unlikely to cause damage.
Shaking was reported as far as El Reno and parts of western Oklahoma City, though no damage or injuries have been confirmed. The quick succession of quakes highlights Oklahoma’s continued seismic activity, which has been linked in past years to wastewater injection tied to oil and gas operations.
Emergency managers remind residents to keep heavy items secured, know safe spots inside their homes, and be prepared for aftershocks. While Monday’s quakes were relatively minor, officials say additional tremors remain possible in the coming days.
