Basin and Range
Earth science; Seismology
An area of the southwestern United States characterized by roughly parallel mountain ranges and valleys, formed by a series of tilted fault blocks, and brought about by tectonic ...
blind thrust fault
Earth science; Seismology
A shallow-dipping reverse fault which terminates before it reaches the surface. When it breaks, therefore, it may produce uplift, but never any clear surface rupture. Many ...
conjugate (faults)
Earth science; Seismology
Describes a pair of intersecting (or nearly intersecting) faults, the slip motions of which are opposite (e.g., right-lateral and left-lateral), so as to accomodate the rotation ...
decollement
Earth science; Seismology
A detachment fault; a fault where crustal deformation causes separation along a boundary of rock types, typically between so-called crystalline "basement" rock and overlying ...
dip slip
Earth science; Seismology
Fault movement (slip) that is parallel to the dip of the fault. This can describe both normal slip and reverse slip.
surface rupture
Earth science; Seismology
The breakage of ground along the surface trace of a fault caused by the intersection of the fault surface area ruptured in an earthquake with the Earth's surface.
surface trace
Earth science; Seismology
The intersection of a fault plane with the surface of the Earth. It is sometimes, but not always, expressed at the surface by geomorphic evidence (ridges, valleys, saddles, etc.).
