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 Here’s a comparison damage map. This compares a 6 point (plus) earthquake in 1895 that occurs on the New Madrid Seismic Zone to the actual damage zone of the 1994 Northridge earthquake which sent damaging seismic waves throughout Los Angeles, California. The 1811–12 New Madrid earthquakes (/ ˈ m æ d r ɪ d /) were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day. Two additional earthquakes of similar magnitude followed in January and February 1812. They remain the most powerful earthquakes to hit.

The goal of their 2009 analysis was to plan for a modern recurrence of quakes that happened along the New Madrid fault more than 200 years ago, in 1811 and 1812. The New Madrid fault is expected to generate a large-scale earthquake within the next 50 years. Uncertainty is the maddening aspect of earthquakes.

Bicentennial of the 1811-1812 New Madrid earthquake sequence December 2011-2012. A series of earthquakes hit the New Madrid seismic zone of southeastern Missouri, northeastern Arkansas, and adjacent parts of Tennessee and Kentucky, in December 1811 to February 1812. Three earthquakes had a magnitude of 7.0 or greater. This animation shows the simulated ground motion of the Earth’s surface that could occur in the central U.S. region for a magnitude 7.7 strike-slip earthquake on the southern section of the New Madrid seismic zone.The simulation is based on a detailed geologic model of the central U.S. and is intended to show the general character of the long-period ground shaking expected for a large.
