Computer Simulation of a Magnitude 7.7 Earthquake in the New Madrid …
The solid straight line in the middle of the New Madrid seismic zone is the surface projection of the modeled fault, which ruptures in the simulation. The colors are keyed to the peak intensity of ground velocity at the surface.
New Madrid seismic zone - Wikipedia
The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), is a major seismic zone and a prolific source of intraplate earthquakes (earthquakes within a tectonic plate) in the Southern and Midwestern United States, stretching to the southwest from New Madrid, Missouri.

In the New Madrid region, the earthquakes dramatically affected the landscape. They caused bank failures along the Mississippi River, landslides along Chickasaw Bluffs in Kentucky and Tennessee, and uplift and subsidence of large tracts of land in the Mississippi River floodplain.

The older highways and railroad bridges that cross the Mississippi River, as well as older overpasses, would likely be damaged or collapse in the event of a major New Madrid earthquake. Some of the bridges and pipelines crossing the Wolf River might be damaged or destroyed.
Facts about the New Madrid Seismic Zone - Missouri
While not as well known for earthquakes as California or Alaska, the New Madrid Seismic Zone (NMSZ), located in southeastern Missouri, northeastern Arkansas, western Tennessee, western Kentucky and southern Illinois, is the most active seismic area in the United States, east of the Rocky Mountains.
Earthquake Hazards near the New Madrid Fault Zone
Earthquakes in the New Madrid Fault Zone. The New Madrid fault zone (NMFZ) is a long-established weakness in the Earth’s crust in the central and eastern US where earthquakes have occurred for hundreds of millions of years.
1811–1812 New Madrid earthquakes - Wikipedia
New Madrid fault and earthquake-prone region considered at high risk today. The 1811–1812 New Madrid earthquakes 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.
New Madrid Seismic Zone - Encyclopedia Britannica
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.
Types of damage that could result from a great earthquake in the …
What would happen if a series of earthquakes as large and numerous as the "New Madrid" earthquakes were to occur in the New Madrid seismic zone today? Photographs 1-10 show typical damage to structures that occurred during various earthquakes in the United States.
Earthquakes on the Mississippi: The New Madrid Seismic Zone
The New Madrid Seismic Zone lies within the Reelfoot Rift. To earthquake researchers like Hough, this region is an enigma. As her email notes, there are a lot of other failed mid-continent rifts in North America.
