Quake Shakes Stillwater Area
OKLAHOMA CITY (AP) — An earthquake has rattled parts of north-central Oklahoma.
The U.S. Geological Survey says the 3.5 magnitude earthquake was recorded at about 8 a.m. Tuesday about 6 miles southwest of Stillwater in Payne County. It occurred at a depth of less than 2 miles.
No damage or injuries were immediately reported. Geologists say earthquakes of magnitude 2.5 to 3.0 are generally the smallest that are felt by humans and that damage is not likely in quakes below magnitude 4.0.
The Oklahoma Geological Survey has said it is likely that many recent earthquakes in the state are being triggered by the injection of wastewater from oil and natural gas drilling operations.
