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. The New Madrid fault system was responsible for the ...
A fault trace or fault line is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geologic maps to represent a fault. [3] [4] A fault zone is a cluster of parallel faults. [5] [6] However, the term is also used for the zone of crushed rock along a single fault. [7]

The Wasatch Fault. Dates indicate approximately when the most recent strong (magnitude greater than 6.5) earthquake occurred on a fault segment. The Wasatch Fault is an active fault located primarily on the western edge of the Wasatch Mountains in the U.S. states of Utah and Idaho. The fault is about 240 miles (390 kilometres) long, stretching ...
The Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas to the east. [1] Spanning more than 185 miles (298 km) in New York, New Jersey, and Pennsylvania, it is perhaps
The Hayward Fault Zoneis a right-lateral strike-slip geologic faultzone capable of generating destructive earthquakes. The fault was first named in the Lawson Report of the 1906 San Francisco Earthquake in recognition of its involvement in the earthquake of 1868.[1] This fault is about 119 km (74 mi) long,[2]situated mainly along the western ...
San Andreas Fault. The San Andreas Fault is a continental right-lateral strike-slip transform fault that extends roughly 1,200 kilometers (750 mi) through the U.S. state of California. [1] It forms part of the tectonic boundary between the Pacific Plate and the North American Plate. Traditionally, for scientific purposes, the fault has been ...
Seattle Fault. The Seattle Fault cuts across Puget Sound and into Seattle itself. Restoration Point in the foreground, Alki Point is barely seen at the right edge of the picture. The Seattle Fault is a zone of multiple shallow east–west thrust faults that cross the Puget Sound Lowland and through Seattle (in the U.S. state of Washington) in ...
