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 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.
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.

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 ...
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 ...
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]
Both of the recent earthquakes struck near one of California’s lesser-known regions of tectonic activity, known as the Almanor Fault Zone. “Most faults are actually zones, at different scales ...
The 1888 earthquake in Río de la Plata was an intraplate quake, [8] from reactivated faults in the Quilmes Trough, far from the boundaries of the South American plate. With a magnitude greater than 5.0 it was felt "in the cities of Buenos Aires, La Plata and other small towns and villages along the Rio de Plata coastal regions."
