Live on the New Madrid fault where if 1811and 12 were today would likely be the worst disaster ever to befall the U.S. .. Huge area was involved..fish on two Huge lakes that were created overnight in S. Illinois and West Tennessee ... the Mississipi river near my house ran backwards for a good while and today every bridge and masonry building between St Louis and Memphis would be gone. A 4.9 ..though the duration was a bit disconcerting was not anything to worry bout. One shower..and then a magnificent day.
