I know that people usually think of the West Coast and Pacific ring of fire when earthquakes come to mind (and yes they should), but if you are one of the 15 million people living in Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri and Tennessee, you could be affected by a quake along the New Madrid fault (the second most active fault in the country, btw), but those who are most in danger, according to the U.S. Geological Survey are the one million people who call the Memphis, Tennessee area home. The last major quakes to hit the area in 1811 in 1812 were between 7.0 and 8.0 in magnitude and made the Mississippi flow backward.  The Red Cross Safety checklist is always helpful.
