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 Ramapo Fault zone is a system of faults between the northern Appalachian Mountains and Piedmont areas ... Green lines indicate the trace of the Ramapo fault ...
What are the fault lines under New York and New Jersey? Fault lines are fractures between blocks of rock in the Earth’s crust, the layer closest to the surface. These lines allow tectonic plates ...
All four West coastal states sit on significant offshore or nearshore earthquake fault lines, each of which could trigger an underwater earthquake and tsunami. Small tsunami risk on the East coast.
Simplified fault map of southern California The faults of Southern California viewed to the southeast, as modeled by the Southern California Earthquake Center. Highlighted in purple are the San Andreas Fault (left) and Santa Monica Bay complex (right). The foreground is in the Santa Barbara Channel, the east-trending zone marks the Transverse ...
The Almanor Fault Zone contains both strike-slip faults, where the earth moves from side to side; and “normal” faults, “where there’s extension in the crust, so things are being pulled ...
The Seattle Fault is a zone of complex thrust and reverse faults – between lines E and F on the map – up to 7 km wide and over 70 km long that delineates the ...
