ST LOUIS (LALATE) – An Oklahoma earthquake today 2013 near the Texas border stuck just outside of Gainesville this morning. The Oklahoma earthquake today September 22, 2013 follows another quake in the state near Oklahoma City on Sunday, as reported on LALATE at the time. No reports of injuries have yet to be indicated by local news.
A 3.2 magnitude Oklahoma earthquake today near the Texas border struck just after 6:40 am local time. The quake was just miles north of Gainesville. But it posted a nominal depth. USGS indicates to news that the quake started only three miles below ground level. As a result the quake could be felt across the region.
Officials tell news that the quake started nine miles south of Lone Grove, Oklahoma and ten miles southwest of Ardmore. The quake was twenty-nine miles north of Gainesville, Texas and forty-four miles west of Denison, Texas. The quake was also about one miles south of Oklahoma City.
Oklahoma and Texas have been the site of several quakes per month since early summer. Officials tell news that today’s quake is on a region frequently filled with faults on bedrock.
“Earthquakes east of the Rocky Mountains, although less frequent than in the West, are typically felt over a much broader region. East of the Rockies, an earthquake can be felt over an area as much as ten times larger than a similar magnitude earthquake on the west coast.”
Also, if faults exist, they are built upon old bedrock. “Earthquakes everywhere occur on faults within bedrock, usually miles deep. Most of the region’s bedrock was formed as several generations of mountains rose and were eroded down again over the last billion or so years.”
But are they active fault lines through this region? USGS tells news that “few earthquakes east of the Rockies can be linked to named faults. It is difficult to determine if a known fault is still active and could slip and cause an earthquake. In most areas east of the Rockies, the best guide to earthquake hazards is the earthquakes themselves.”
