Some of the worst earthquakes in the U.S. occurred during the winter of
1811-1812 when violent tremors shook the Mississippi River Valley along the
New Madrid Seismic Zone. The series of at least three magnitude 7 or greater earthquakes changed the landscape of the Central U.S.
Geologists tell us that a damaging earthquake could strike the central United States at anytime. If earthquakes of similar magnitude happened today, their effects could have catastrophic impacts on our national transportation, communication, utility and financial systems.
