Seismology

Halfspace

Earth science; Seismology

A mathematical model bounded by a planar surface but otherwise infinite. Properties within the model are commonly assumed to be homogeneous and isotropic, unlike the Earth itself, which is ...

Body wave

Earth science; Seismology

A seismic wave that can travel through the interior of the earth. P-waves and S-waves are body waves.

Bore

Earth science; Seismology

A single water wave with an almost vertical front.

A prism of deformed sediments in the upper plate of a subduction zone near the deformation front, formed in part by accretion of sediments of the downgoing plate, but also including sediments derived ...

Microseism

Earth science; Seismology

A more or less continuous motion in the Earth that is unrelated to an earthquake and that has a period of 1. 0 to 9. 0 seconds. It is caused by a variety of natural and artificial agents.

Poisson solid

Earth science; Seismology

When the rigidity and the other Lame (unnamed) constant are equal, Poisson's ratio is 0. 25 and is used as the approximation in most seismology problems.

Time-predictable model

Earth science; Seismology

With reference to earthquakes, a recurrence model in which the time interval between two successive large earthquakes is proportional to the amount of seismic displacement of the preceding ...
