Several of the largest historical earthquakes to strike the continental United States occurred in the winter of 1811-1812 along the New Madrid Seismic Zone, which stretches from just west of Memphis, Tennessee into southern Illinois. These earthquakes produced at least three temblors between magnitude 7-8, and hundreds of aftershocks.
In 2011 and 2012, there will be events held throughout the central United States observing the 200th Anniversary of the great 1811 and 1812 New Madrid earthquakes that forever changed the mid-western landscape. These quakes were felt across the U.S. and as far south as the Gulf of Mexico, and as far north as Canada. Organizations from across the United States will participate in the bicentennial events, which range from conferences, workshops, public outreach events, multi-state earthquake exercises, field trips, and more.
The New Madrid Bicentennial (NMB) events are being organized by the following organizations, with additional help from many volunteers across the region and nation. Our success in promoting earthquake awareness could not be possible with out their help.
