The New Madrid Seismic Zone is a major earthquake-prone area located in the central United States, primarily affecting parts of Missouri, Arkansas, Tennessee, and Kentucky. It is named after the town of New Madrid, which experienced a series of significant earthquakes in 1811 and 1812. These quakes were among the largest in U.S. history, causing widespread damage and altering the landscape. The region remains seismically active, with ongoing monitoring by the United States Geological Survey (USGS). Scientists study the New Madrid Seismic Zone to better understand earthquake risks and improve preparedness for potential future seismic events.
