LOS ANGELES AP — The New Madrid fault zone in the nations midsection is active and could spawn future large earthquakes, scientists reported Thursday.Its “not dead yet,” said U.S. Geological Survey seismologist Susan Hough, who was part of the study published online by the journal Science.Researchers have long debated just how much of a hazard New Madrid MAD-rihd poses. The zone stretches 150 miles, crossing parts of Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri and Tennessee.In 1811 and 1812, it unleashed a trio of powerful jolts — measuring magnitudes 7.5 to 7.7 — that rattled the central Mississippi River valley. Chimneys fell and boats capsized. Farmland sank and turned into swamps. The death toll is unknown, but experts dont believe there were mass casualties because the region was sparsely populated then.  Full Article Study: New Madrid fault zone alive and active – Yahoo News.

Here is a video from You tube it’s from last year, but the specifics are still pertinent.
