I can report on this first hand. About 8:20 this morning there was an earthquake with its epicenter about 9 miles northeast of El Dorado, Arkansas, around 3.0 on the Richter Scale. I work on the third floor of a four story office building. I felt at least two strong shocks come through the building. Our building was evacuated and we were sent home for the day while the building is checked for any structural damage. Hopefully, there was none, but if there was I know I wouldn't want to be in there if the floors started pancaking on each other. My first thought was that maybe a local chemical plant or refinery had blown up. Then, I wondered whether the New Madrid fault up around Memphis had finally let go and the mega-earthquake that seismologists have been predicting for years finally happened. Fortunately, it wasn't anything like that at all. I guess now I know a bit what the folks out in California go through.
