Gary is over here smiling as you people speak of earthquakes.
Though I'm not sure that it's something good to win at, the earthquake activity along the New Madrid fault line surpasses CA. In the known history of the world, no other earthquakes have lasted so long or produced so much evidence of damage as the New Madrid earthquakes. Three of the earthquakes are on the list of America’s top earthquakes: the first one on December 16, 1811, a magnitude of 8.1 on the Richter scale; the second on January 23, 1812, at 7.8; and the third on February 7, 1812, at as much as 8.8 magnitude. After the February 7 earthquake, the Mississippi actually ran backwards for several hours. The force of the land upheaval 15 miles south of New Madrid created Reelfoot Lake, drowned the inhabitants of an Indian village; turned the river against itself to flow backwards; devastated thousands of acres of virgin forest; caused sand blows, created two temporary waterfalls in the Mississippi, and forever changed the course of the river. There are literally 1000's of recorded quacks over the years. By and large they occur in areas without significant concentrations of structures, so most people have learned to ignore them as a part of daily life.
