Reelfoot Rift and the New Madrid Seismic Zone in a 3D topographic image. Magnetic potential map of the Reelfoot Rift. The New Madrid Seismic Zone (NMSZ) ( / ˈmædrɪd / ), sometimes called the New Madrid Fault Line, is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and ...
This map shows earthquakes (circles) of the New Madrid and Wabash Valley seismic zones (orange patches). Red circles indicate earthquakes that occurred from 1974 to 2002 with magnitudes larger than 2.5 located using modern instruments (University of Memphis).

Maps. Map Releases. Types of damage that could result from a great earthquake in the New Madrid, Missouri, seismic zone. January 1, 1984. View Plate. In the winter of 1811–1812 a series of three great earthquakes occurred in the New Madrid seismic zone.
New Madrid Seismic Zone (NMSZ), region of poorly understood, deep-seated faults in Earth’s crust that zigzag southwest-northeast through Arkansas, Missouri, Tennessee, and Kentucky, U.S. Lying in the central area of the North American Plate, the seismic zone is about 45 miles (70 km) wide and about.
