Eliza Bryan in New Madrid, Territory of Missouri, wrote the following eyewitness account in 1816:“The zone remains active today. In recent decades, minor earthquakes have continued.
Ping, ping, ping, ping, Over the past three years, Magnani has used these tools to map the ground below the river in the New Madrid Seismic Zone, a fault system stretching about 150 miles from Cairo, Illinois, to Marked Tree, Arkansas. “Some had archaeological sites on top of them with 2,000-year-old artifacts,” Tuttle says.

There is a 25 to 40 percent chance, in a 50-year time span, of a magnitude 6.0 or greater earthquake. That’s the only way we can hope to understand intraplate earthquakes—and ultimately keep people safe.” Earthquakes in this zone have the potential to cause damage in the states of Alabama, Arkansas, Illinois, Indiana, Kentucky, Mississippi, Missouri, and Tennessee. Earthquakes in Mississippi and vicinity 1811-2010. By studying evidence of past quakes and closely monitoring ground motion and current earthquake activity, scientists attempt to understand their causes and recurrence intervals” (New Madrid fault and Earthquake prone region considered at high risk today (Wikipedia)Damage-range comparison between a moderate New Madrid zone earthquake (1895, magnitude 6.8), and a similar Los Angeles event (1994, magnitude 6.7) (Ibid. Smithsonian Magazine Work on the Mississippi map was done in collaboration with the Mississippi Department of Environmental Quality, Office of Geology. The area of strong shaking associated with these shocks is two to three times as large as that of the 1964 Alaska earthquake and 10 times as large as that of the 1906 San Francisco earthquake” (USGS: Historic Earthquakes).The New Madrid earthquakes were felt as far away as Canada and the eastern seaboard, the tremors caused church bells to ring in Boston and Philadelphia, the earth’s surface remained in a state of constant motion for nearly four months, several towns were destroyed, an 18 by 5 mile lake was created (Reelfoot Lake in Tennessee), and it appeared that the Mississippi River temporarily ran backwards. The number Mississippi Earthquakes Each New Madrid earthquake had a magnitude of 7.5 or greater, making them three of the most powerful in the continental United States and shaking an area ten times larger than that affected by the magnitude 7.8 San Francisco earthquake of 1906.The Midwest was sparsely populated, and deaths were few.

“There’s no way the New Madrid earthquakes were a one-time freak event.” The Midwest had been slammed by violent quakes around A.D. 1450 and 900 and 2350 B.C.—and probably more often.Most earthquakes occur at the edges of the earth’s 15 major tectonic plates; when they slide against each other, the ground gets a jolt. It’s the most active seismic area in the United States east of the Rockies, with about 200 small quakes a year.Magnani’s most startling discovery came south of the seismic zone: two faults, one near Memphis, both active in the past 10,000 years. Early one morning, Magnani, a seismologist at the University of Memphis, guided a steel cylindrical air gun from a tugboat into the silty waters of the Mississippi River and then tested it. The risk of a smaller, though still devastating, 6.0 earthquake in the next 50 years is 25 to 40 percent. | (Map: Guilbert Gates; Source: USGS National Seismic Hazard Maps, 2008) New Madrid earthquakes of 1811–12, series of three large earthquakes that occurred near New Madrid, Missouri, between December 1811 and February 1812.

This map summarizes two centuries of earthquake activity in Mississippi.
Early in 1811, Tecumseh, Chief of the Shawnees, warned reluctant warrior-tribes that he would stamp his feet and bring down their houses if they didn’t join him in an effort to drive the white man out of Indian territories.

New forecasts estimate a 7 to 10 percent chance, in the next 50 years, of a repeat of a major earthquake like those that occurred in 1811-1812, which likely had magnitudes of between 7.5 and 8.0.

Then, two decades ago, paleoseismology expert Martitia Tuttle and her colleagues began dissecting “sand blows” in the five states surrounding New Madrid. At 2:15 a.m. on December 16, 1811, residents of the frontier town of New Madrid, in what is now Missouri, were jolted from their beds by a violent earthquake. The shaking rang church bells in Charleston, South Carolina, and toppled chimneys as far as Cincinnati, Ohio.“The screams of the affrighted inhabitants running to and fro, not knowing where to go, or what to do—the cries of the fowls and beasts of every species—the cracking of trees falling...formed a scene truly horrible,” wrote one resident.As people were starting to rebuild that winter, two more major quakes struck, on January 23 and February 7. Ongoing research should help identify which areas are most in danger.“We need a broader, yet clearer picture of all the networks of faults that have been active in the region,” says Magnani. But the newfound faults lie outside the rift.
