A magnitude 5.6 earthquake in central Oklahoma Saturday night was felt throughout Clay County.
According to the United States Geological Survey, the epicenter of the quake was located 21 miles north northeast of Shawnee, Okla., near the town of Sparks. It is the most recent in a series of earthquakes and tremors near the town, which began at 2:12 a.m. with a magnitude 4.7 quake. The USGS web site reports that the first quake was felt In Byers. The initial quake produced nearly 40 aftershocks.
The most recent quake was initially reported as 5.2 in magnitude, but later upgraded to 5.6.
The quake occurred at 10:53 p.m., and caused windows and shelved items to rattle in Henrietta. Clay County residents from Henrietta, Dean, Joy, Arrowhead Ranch Estates, Bluegrove and Bellevue reported feeling the Saturday night tremor via The Pioneer Sentinel Facebook page.
It has since been determined by the USGS that Saturday night’s quake is the largest in Oklahoma history. Reports made to the USGS indicate that the quake was felt as far south as San Antonio. Reports poured into the USGS website from New Mexico, Colorado, Louisiana, Arkansas, Missouri, Illinois, Kansas and Nebraska.
