Locations of quakes magnitude 2.5 or greater in the Wabash Valley (upper right) and New Madrid (lower left) Seismic Zones. The Wabash Valley seismic zone (also known as the Wabash Valley fault system or fault zone) is a tectonic region located in the Midwestern United States, centered on the valley of the lower Wabash River, along the state line between southeastern Illinois and southwestern ...
The USGS issued a fact sheet in 2009 stating the estimate of a 7–10% chance of a New Madrid earthquake of magnitude comparable to one of the 1811–12 quakes within the next 50 years, and a 25–40% chance of a magnitude 6 earthquake in the same time frame. [32] In July 2014, the USGS increased the risk assessment for the New Madrid area. [33]

“Instead of allowing this event to scare you, use this real world event to help you review and update your family emergency plan,” public safety official said.
Nearly 75% of the country is at risk for a potentially damaging earthquake in the next 100 years, according to a recently updated map from the U.S. Geological Survey. The map is the first to ...
A magnitude 5 earthquake may affect 5-15 times larger of an area in the New Madrid Seismic Zone compared to California, largely due to the crustal geology of the two areas.
Pressure on the fault where the 1811–1812 New Madrid earthquakes occurred was believed to be increasing, [23] but a later study by Eric Calais of Purdue University and other experts concluded the land adjacent to the New Madrid fault was moving less than 0.2 mm (0.0079 in) a year, increasing the span between expected earthquakes on the fault ...
