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 ...
Situated in a stable continental region of the Midwestern United States, the Wabash Valley seismic zone (WVSZ) is an area of dispersed seismic activity that encompasses the border areas of Illinois, Indiana, and Kentucky.
Mount Carmel is within the Wabash Valley seismic zone. On April 18, 2008, at 09:36:56 UTC (04:36:56 Central) an earthquake of 5.2 magnitude was centered near the city, and just hours later an aftershock of 4.6 magnitude shook Mt. Carmel and its residences.
Earthquakes in the New Madrid and Wabash Valley seismic zones from 1974 to 2002, with magnitudes larger than 2.5. The zone had four of the largest earthquakes in recorded North American history, with moment magnitudes estimated to be as large as 7 or greater, all occurring within a 3-month period between December 1811 and February 1812. Many of ...

The earthquake ruptured within a fault zone known as the Ramapo system, Simons said. It’s a zone in relatively ancient rock that contains old faults and cracks from ancient tectonic processes.
Today, the Cascadia Subduction Zone remains eerily quiet. In other subduction zones, scientists often observe small earthquakes frequently, which makes the area easier to map, according to ...
The New Madrid seismic zone and the Wabash Valley seismic zone intersect the southern portion of the basin. The major structural features within the basin include the La Salle anticlinal belt, the DuQuoin monocline , the Cottage Grove fault system , and the Fairfield Basin .
