New Madrid Seismic Zone Earthquake Hazard Article and Map. Vulnerable Communities in the Mississippi Valley There is broad agreement in the scientific community that a continuing concern exists for a major destructive earthquake in the New Madrid seismic zone.
Many structures in Memphis, Tenn., St. Louis, Mo., and other communities in the central Mississippi River Valley region are vulnerable and at risk from severe ground shaking. This assessment is based on decades of research on New Madrid earthquakes and related phenomena by dozens of Federal, university, State, and consulting earth scientists. Considerable interest has developed recently from media reports that the New Madrid seismic zone may be shutting down.
These reports stem from published research using global positioning system (GPS) instruments with results of geodetic measurements of strain in the Earth’s crust. As part of the consensus-building process used to develop the national seismic hazard maps, the U.S. The Geological Record Continuing Seismic Activity.

Atkinson, 1989, The Next New Madrid Earthquake, Southern Illinois University Press The recent earthquake which struck Kobe, Japan, resulted in the loss of over 5000 lives and millions of dollars in property.
However, large parts of the United States are also subject to large magnitude quakes - quakes which could be far more powerful than the Kobe quake! Although we tend to think of California and Alaska as the places where most of our earthquakes occur, the fact is that the central U.S. has been the site of some very powerful earthquakes. In the past three centuries, major earthquakes outside of California and Alaska generally occurred in sparsely-settled areas, and damage and fatalities were largely minimal. But some took place in areas that have since been heavily built up. Eyewitness Accounts of the 1811 and 1812 Earthquakes Legend General Description Maps and Graphics.

This was the first of three large (magnitude 7.5 - 8.0) earthquakes and thousands of aftershocks to rock the region that winter.Survivors reported that the earthquakes caused cracks to open in the earth's surface, the ground to roll in visible waves, and large areas of land to sink or rise.
The crew of the New Orleans (the first steamboat on the Mississippi, which was on her maiden voyage) reported mooring to an island only to awake in the morning and find that the island had disappeared below the waters of the Mississippi River. Damage was reported as far away as Charleston, South Carolina, and Washington, D.C. These dramatic accounts clearly show that destructive earthquakes do not happen only in the western United States.

From page 106 of above, we note: "The writer does not wish at this time to urge a structural origin for Crowley Ridge, but simply desires to call attention to the occurrence of smaller parallel lines of uplift and depression due to relatively recent warping and to suggest that an earlier and stronger warping of the same nature and in the same direction might have produced a similar uplift along the Crowley Ridge axis.
"It isn’t the fracking that’s causing the quake. The New Madrid Seismic Zone (NMSZ) lies directly above an ancient failed rift, the Reelfoot rift. Jan. 1812. Emergency-Specific Preparedness Information.
