New Madrid – Hints of Activity
USA Today has a follow up article to the study published in Nature in June that talked about the dangers of an earthquake on the New Madrid fault. Scientists believe the faults are a failed “rift” zone, created when Earth’s crust was separating into continents. The crust fractured but did not split apart. That left a weak spot where earthquakes occur. History shows that the New Madrid earthquakes were fearsome. In 1811 and 1812, three major quakes triggered landslides, caused the Mississippi River to flow backward, swamped boats, created a lake, leveled New Madrid, Mo., and knocked down chimneys and cabins in St. Louis and Cincinnati. The shaking caused church bells to ring in Boston. And another article.
