Oklahoma Geologic Survey seismograph trace of this morning's quake
A 5.1 earthquake struck Oklahoma this morning, with the epicenter 8 miles southeast of Norman. People reported feeling the quake all across the state, and into Kansas, Missouri and Texas. Two people in the Norman area received minor injuries.
Yes, Oklahoma does get earthquakes from time to time. At 5.1 on the Richter scale, this is the second-largest earthquake to hit Oklahoma in state history. The record holder took place on April 9th, 1952, and was centered around El Reno.
On a lighter note, Ben Burnsed, conservative activist from Stillwater, believes that he has discovered the cause of the earthquake: "Rumour has it the 4.5* Earthquake in Oklahoma today was caused by a stampede of DONKEYs and RINOs being driven out by a herd of ELEPHANTS. We expect this tremor to spread across the country over the next 3 weeks."
[*: the quake was initially a 4.3 or 4.5, but the OGS upgraded it to 5.1]
