The New Madrid fault system was responsible for the 1811–1812 New Madrid earthquakes and has the potential to produce large earthquakes in the future. Since 1812, frequent smaller …

New Madrid seismicity is spatially associated with the Reelfoot rift and may be produced by movement on old faults in response to compressive stress related to plate motions.

Some Earth scientists suggest that fracturing in this region resulted from stresses brought on by the downcutting of the Mississippi River into the surrounding landscape between 10,000 and …

Every year hundreds of small earthquakes occur in the NMSZ, however, most are too small to be felt by humans and can only be detected by sensitive instruments. The faults on which the …

For the first time in more than 200 years, seismic instruments have detected a deep shift within the New Madrid Fault Zone, the most dangerous earthquake system in the central United States.

3 days ago · This sequence of three very large earthquakes is usually referred to as the New Madrid earthquakes, after the Missouri town that was the largest settlement on the Mississippi …

The United States is crisscrossed by numerous fault lines, many of which have the potential to unleash significant earthquakes. Recent studies and seismic activities have heightened …
