In spite of my fearless prediction, there has been no significant seismic activity in California this fall, but a 4.7 earthquake was recorded this morning roughly 20 miles northeast of Oklahoma City.
It was felt across much of Oklahoma, parts of southern Kansas and southwestern Missouri.
The first aftershock happened in the same area, according to the United States National Weather Service office in Norman, which posted this message to Facebook at about 3 a.m.
Yes, we have had an earthquake in Oklahoma this morning. The U.S. Geological Survey's initial estimate is a magnitude 4.7 that occurred near Prague, OK, around 2:12 AM CDT. There has also been a 3.4 magnitude aftershock at the same location. We felt it here in Norman, and have received calls from as far away as Wichita Falls, TX. Also, the weather offices in Topeka, KS, and Pleasant Hill, MO, felt this one. You can find details and report your experience at http://earthquake.usgs.gov .
According to the USGS, that first aftershock was a 3.5-magnitude temblor northeast of Shawnee. The next two aftershocks, one at 2:44 a.m. and the other at 2:50 a.m., were 2.7-magnitude. That was followed by the most recent 3.3-magnitude quake just after 4:00 this morning.
The quakes I reported yesterday were followed last night by a 5.6 tremor - largest in Oklahoma history - centered near Sparks, OK, another small town in the Oklahoma city area. There are reports this morning of damaged roads and buildings, and a few minor injuries.
