An active fault is a fault that is likely to become the source of another earthquake sometime in the future. Geologists commonly consider faults to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. [1] Active faulting is considered to be a geologic hazard – one related to earthquakes as
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]

Some use the term "transform fault" to describe the seismically and tectonically active portion of a fracture zone after John Tuzo Wilson's concepts first developed with respect to the Mid-Atlantic Ridge. [2] The term fracture zone has a distinct geological meaning, but it is also used more loosely in the naming of some oceanic features.
A seismic gap is a segment of an active fault known to produce significant earthquakes that has not slipped in an unusually long time, compared with other segments along the same structure. There is a hypothesis or theory that states that over long periods, the displacement on any segment must be equal to that experienced by all the other parts ...
New Jersey experienced a 4.8 magnitude earthquake, according to the U.S. Geological Survey. Here is the science behind the cause and the Ramapo Fault.

A fault zone that displaces sealing units and reservoir rocks can act as a conduit for hydrocarbon migration. [6] The fault zone itself has higher storage capacity (specific capacity) than that of the reservoir rocks, therefore, before the migration to other units, the fault zone has to be fully filled [6] (Gif 3). This can slower and ...
