The Edmond Sun
A 3.3 magnitude earthquake rattled Logan County Tuesday morning, the Oklahoma Geological Survey reported.
The agency stated that the temblor occurred at 8:49 a.m. and it was recorded by 16 seismic stations. The U.S. Geological Survey reported that a magnitude 3.0 earthquake occurred at 8:49 a.m. 8 miles north-northeast of Luther, 19 miles east-northeast of Edmond.
Initial information about earthquakes is considered to be preliminary.
Earthquakes are not unusual in Oklahoma, but they are often too small to be felt.
From 1972-2008, about 2-6 earthquakes a year were recorded by the USGS’ National Earthquake Information Center; they were scattered broadly about the east-central part of the state.
In 2008, the rate of Oklahoma quakes began to rise, with more than a dozen occurring in the region east-northeast of Oklahoma City and southwest of Tulsa, according to the USGS. In 2009, nearly 50 earthquakes were recorded, many big enough to be felt. In 2010, the activity continued.
On Nov. 5, 2011, the largest earthquake to hit Oklahoma in modern times, a magnitude 5.6 temblor, was recorded at 10:52 p.m., 42 miles east-southeast of Guthrie. It was preceded by a magnitude 4.7 quake.
They occurred along the Wilzetta fault, according to the USGS. The Meers fault is located in south-central Oklahoma. A quake like the 5.6 magnitude event is believed to be capable of striking anywhere in eastern North America at irregular intervals.
Scientists continue to study relevant Oklahoma geological features.
