American Earthquake, the Great New Madrid, quake: first (and 2nd strongest) in 54-day series of massive earthquakes that hit the Mississippi Valley 1811-12. The shock was felt over 2/3 of then US, about 1 million square miles; stopped clocks in Boston, rang bells in Norfolk, VA, land dropped 30-40 ft in some places, course of Mississippi River changed, two new lakes formed; land so severely fissured it could not be crossed on horseback; floods, subsidence & "sand blows" (eruptions of sand and mud), destroyed farmland, timberland and prairie - "the most violent & prolonged series of earthquakes in US history." The final quake, 2/07/1812, c. 3:45 AM LMT, (acc to Nuttli) centered at New Madrid, MO, was the most powerful, estimated at 8.7 Richter.
