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 ...
These lines allow tectonic plates to move and earthquakes occur when two plates slide past each other. The Ramapo Fault System is the longest in the northeastern U.S., stretching from Pennsylvania ...
A damaging earthquake affecting New York City in 1884 was incorrectly argued to be caused by the Ramapo fault, likely because it is the most prominent mapped fault in the greater New York City area. At the present, the relationship between faults and earthquakes in the New York City area is understood to be more complex than any simple ...
A map by the California Geological Survey shows faults near the Lake Almanor area in Plumas County, where a magnitude 5.5 earthquake struck Thursday, May 11, 2023, followed by a magnitude 5.2 ...
The U.S. Geological Survey (USGS) reported that a magnitude 5.8 M w earthquake hit Virginia on Tuesday, August 23, 2011, at 17:51:04 UTC (1:51 pm Eastern Daylight Time). The quake occurred at an approximate depth of 3.7 miles and was centered in Louisa County (location at 37.936°N, 77.933°W), 5 miles SSW of Mineral, Virginia and 37 miles NW of Richmond, Virginia's capital.

These earthquakes are sometimes referred to as crustal earthquakes, and they are capable of causing significant damage due to their relatively shallow depths. A damaging magnitude 7 interplate earthquake occurred on the Seattle Fault around 900–930 CE [14] that generated 3 meters of uplift and a 4-5 meter tsunami. [15]
