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.
The Reelfoot rift is identified today as a subsurface system of fractures and faults in the earth's crust. 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.
5 days ago · Central United States, ( The Lake Tribune) – A groundbreaking computer simulation has offered a stark visualization of the potential devastation a magnitude 7.7 earthquake could unleash in the central United States, particularly within the New Madrid Seismic Zone.
The New Madrid Seismic Zone (NMSZ), sometimes called the New Madrid Fault Line, 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.
Mar 2, 2024 · If you've ever wondered what would happen if the predicted 7.7 earthquake would ever hit the New Madrid Fault Zone in Missouri, wonder no more. A computer simulation shows how many people and cities would be devastated in real-time.
A magnitude 7.6 earthquake in the NMSZ is expected to cause major damage near the fault system in the Missouri Bootheel, northeast Arkansas and western Kentucky and Tennessee.
Feb 1, 2023 · There are hundreds of minor earthquakes each year in Missouri's New Madrid Seismic Zone (NMSZ), but most of them are too small for people living in the area to feel. While several major ...
Mar 4, 2022 · Experts have warned for decades that a large swath of the central U.S. is at high risk for a devastating earthquake from the New Madrid Fault.

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.
A prediction made by climate consultant Iben Browning held that there'd be a "50 percent chance" of a magnitude 7 earthquake rocking the nation on this date. Browning also said that, if the quake came, it'd probably originate near the city of New Madrid (pronounced "MAD-rid") in southeastern Missouri.
