Big Earthquake Could Devastate U.S. Midwest, Experts Warn This April 2006 article discusses the possibility of a large earthquake in "the New Madrid seismic zone -- where Missouri, Kentucky, Arkansas, and Tennessee meet-- [and which] lies in the middle of the North American tectonic plate, thousands of miles from the plate boundaries where earthquakes usually occur."
