The Edmond Sun
Two earthquakes rattled central Oklahoma in the past few days. Christmas evening Edmond residents felt the earth move and Spencer residents felt an earthquake of smaller magnitude on Christmas Day.
Preliminary U.S. Geological Survey reports show that a 3.7-magnitude earthquake struck Christmas Eve near Edmond.
The quake struck at around 9:15 p.m. The USGS said the quake hit 6 miles from Edmond, 13 miles from Choctaw, 14 miles from Guthrie, 15 miles from Midwest City and 16 miles from Oklahoma City.
It was one of three earthquakes reported in central Oklahoma in the hours before, during and after Christmas Day.
The second, a 2.7-magnitude earthquake, struck near Spencer about 4:30 a.m. Wednesday.
A USGS preliminary report says the earthquake’s epicenter was 5 miles north of Spencer and 11 miles northeast of Oklahoma City.
The third earthquake hit at 3:55 p.m. Wednesday. The 2.9-magnitude quake was centered 5 miles south/southwest of Purcell.
Seven days ago, the U.S. Geological survey said a 3.3 earthquake struck about 70 miles north of Oklahoma City near McCord.
On Dec. 7, one of the largest recorded earthquakes in the state’s history occurred at 12:10 p.m. and it was felt in Edmond, Guthrie, Oklahoma City and Norman.
The USGS said it occurred about 5 miles deep and was recorded as a 4.5 earthquake. The Oklahoma Geological Survey measured it as a 4.8 magnitude.
At 1:26 p.m., a magnitude-2.8 aftershock was recorded about 3 miles southeast of Edmond, according to the U.S. Geological Survey.
Another aftershock, with a magnitude of 3.1, was recorded at 5:58 p.m., about 4 miles east of The Village and 6 miles south of Edmond, the survey reported.
Although employees with the Oklahoma Geological Survey are out until Jan. 3, 2014, Austin Holland, OGS seismologist, said Thursday the cause for the earthquakes is a difficult thing to determine.
“We are constantly looking at this, but those sorts of determinations are slow to come. When we return from the break we will be taking a closer look at what has been happening.”
