When small earthquakes shake the central US, citizens often fear the rumbles are signs a big earthquake is coming. Fortunately, a new study instead shows that most of these earthquakes are aftershocks of big earthquakes (magnitude 7) in the New Madrid seismic zone that struck the Midwest almost 200 years ago. Aftershocks go on until the fault recov

The last large earthquakes in the New Madrid seismic zone were magnitude 7-7.5 events in 1811 and 1812. Estimating an accurate earthquake threat for the area, which includes parts of Illinois, Indiana, Tennessee, Arkansas and Kentucky, is crucial for the communities potentially affected.This fault system does not behave as earthquake hazard models

A massive earthquake, estimated at a magnitude between 7.4 to 8.0, struck New Madrid, Missouri, on February 7, 1812. The area was lightly populated at the time, but today the affected cities would include St. Louis, Missouri, Arkansas, Memphis and Nashville, Tennessee. New "CAT scans" of the deep Earth may help figure out why one of the biggest

Saint Louis University Earthquake Center home page offers a wealth of seismic and geological information, with emphasis on the central US. The massive New Madrid earthquakes of 1811-1812 struck a sparsely populated region, but the next big quake - and it WILL HAPPEN - will exert a heavy impact on St. Louis, Memphis, and much of the central US.
