I once turned down a job interview at UT-Martin
New Madrid earthquake threat worries Tenn.
Tennessee's biggest catastrophe will come without warning.
A major earthquake would destroy buildings, roads and bridges along hundreds of miles. The cascading collapse of power, communications and transportation systems would plunge Middle Tennessee into a disaster that would make the May flood seem minor.
Seismologists estimate a 25 percent to 40 percent probability of a major quake within the next 50 years in the New Madrid Seismic Zone, which stretches from Memphis to southern Illinois.
