Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. [2] A fault plane is the plane that represents the fracture surface of a fault. A fault trace or fault line is a place where the fault can be seen
Thrust fault: Active: 2008 Sichuan (M8.0) Lost River Fault: Idaho, United States: Normal: Active: 1983 Borah Peak (M6.9) Lusatian Fault: Germany: Thrust fault: Macquarie Fault Zone >400: South Pacific Ocean: Fault (geology)#Strike-slip faults: Active: 1989 Maquarie Isl.

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.
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 ...
Earthquakes are most common along fault lines, which are fractures that allow the plates to move. Earthquakes occur when two plates suddenly slip past each other, setting off seismic waves that ...
The 800-mile San Andreas Fault is one of the largest fault lines in the world. A meeting of the North American and Pacific tectonic plates, this transform fault (where two tectonic plates move ...
The Ramapo Fault has been blamed for several past earthquakes, but the specific association of any significant earthquake with this fault has yet to be demonstrated. [6] 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 ...
A full fault rupture, estimated to be around a 7.5 magnitude, could kill between 3,000 and 18,000 people, according to US Geological Survey and Southern California Earthquake Center.
