Seismology

Forward modelling problem for seismology

Earth science; Seismology

Describing the seismic waves generated by a know source in a known medium. This is the opposite of the inverse modelling problem.

Converted waves

Earth science; Seismology

Conversion of P to S waves occurs at a discontinuity for non-normal incidence.

Backstop

Earth science; Seismology

Continental rocks in the backarc that are landward from the trace of the subduction thrust fault and that are strong enough to support stress accumulation. These rocks are both igneous and ...

Poisson's ratio

Earth science; Seismology

Gives the absolute value of ratio given by the extension normal to applied compressive stress, divided by the extension parallel to the applied compression.

Volcanism

Earth science; Seismology

Geological process which involved the eruption of molten rock.

Caustic

Earth science; Seismology

Focusing of a wave where the energy is turning above and reflecting off a discontinuity, respectively - constructively interfering. The amplitude may be large, but not infinite. There are two ...

Seismic zonation

Earth science; Seismology

Geographic delineation of areas having different potentials for hazardous effects from future earthquakes. Seismic zonation can be done at any scale - national, regional, local, or site.
