A moderate Magnitude 5.6 earthquake struck Oklahoma at 3:53:10 UTC on Sunday November 5, 2011. The display shows the waveform received in northeastern Ohio. The waveform structure for earthquakes this close is complicated and since we don’t often see them I haven’t spent a lot of time trying to decipher it. The simple body and surface waves are not even listed in the USGS arrival time list shown below:
