It is being described as the most powerful earthquake in Illinois since the 1895 New Madrid quake. I am not sure how anyone can be sure of that, since seismographs and the richter scale had not been invented yet in 1895, but somehow the experts have rated the Richter scale of all the quakes in the last couple hundred years--
I remember this one from 1968-

Ironically, today, April 18, is the 102nd anniversary of the 1906 San Francisco earthquake, the most devastating earthquake in American history--

Jim Les told Kirk Wessler there was NO earthquake but we are keeping our options open in case something develops...but as of now all natural disasters are out indefinetly and we are not expecting any until the end of spring classes when that could change things.
Stay tuned.....
