reverse fault
Earth science; Seismology
A fault in which the displacement is predominantly vertical, and the hanging wall is moved upward with respect to the footwall. Some amount of reverse slip is often seen in ...
Richter scale
Earth science; Seismology
Introduced in 1935 by Charles F. Richter, the Richter scale is a numerical scale for quantifying earthquake magnitude -- typically it refers to local magnitude, but for larger ...
seismic zone (or seismic belt)
Earth science; Seismology
A region of the Earth's crust, generally linear, associated with active seismicity. It may not necessarily be connected with a particular fault or surface fault trace.
sense of slip
Earth science; Seismology
The sense with which one side of a fault slips relative to the other side, in a reference frame defined by a horizontal (level) plane oriented with the pull of Earth's gravity ...
strike
Earth science; Seismology
The direction, or trend, of the line marking the intersection of a fault plane (or another planar geologic feature) with the horizontal. Strike is always at a right angle to dip.
