Seismology
moment of earthquakes
Earth science; Seismology
A measure of earthquake size related to the leverage of the forces (couples) across the area of the fault slip. The rigidity of the rock times the area of faulting times the amount of slip. ...
delta function
Earth science; Seismology
A mathematical generalized function that can be regarded as the limit of any several sequences of continuous function. It also has the "sifting " property where the delta function "picks out" the ...
capable fault
Earth science; Seismology
A fault along which it is mechanically feasible for sudden slip to occur.
earthquake swarm)
Earth science; Seismology
A series of minor earthquakes, none of which may be identified as the main shock, occurring in a limited area and time.
viseoelastic material
Earth science; Seismology
A material which can behave as an elastic solid on a short-time scale and as a viscous fluid on a long-time scale.
coefficient of friction
Earth science; Seismology
A property of rocks that describes the amount of stress that can be accumulated before two bodies of rock will slide past each other. It is related to the roughness or protrusions that the rocks ...
ray theory
Earth science; Seismology
A standard set of approximations used to interpret seismic body-waves based on plane waves and/or spherical waves traveling through a medium.
