The New Madrid seismic zone (NMSZ), sometimes called the New Madrid fault line (or fault zone or fault system), 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.

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 ...
Structures of Kansas showing the Nemaha Uplift/Ridge. The Nemaha Ridge (also called the Nemaha Uplift and the Nemaha Anticline [1]) is located in the Central United States.It is a buried structural zone associated with a granite high in the Pre-Cambrian basement that extends from approximately Omaha, Nebraska to Oklahoma City, Oklahoma.
What are the fault lines under New York and New Jersey? Fault lines are fractures between blocks of rock in the Earth’s crust, the layer closest to the surface. These lines allow tectonic plates ...
New Madrid fault and earthquake-prone region considered at high risk today. The 1811–1812 New Madrid earthquakes were a series of intense intraplate earthquakes beginning with an initial earthquake of moment magnitude 7.2–8.2 on December 16, 1811, followed by a moment magnitude 7.4 aftershock on the same day.
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
A newly found fault line with a rare slanted angle shows why an earthquake rattled New York City in April harder than its epicenter in New Jersey — and may be a bigger seismic activity threat ...
