Seismology

incompressibility

Earth science; Seismology

An index of the resistance of an elastic body, such as a rock, to volume change.

geophone

Earth science; Seismology

An instrument used to record ground in reflection/refraction exploration geophysics and ocean acoustic surveys.

reflector

Earth science; Seismology

An interface between materials of different elastic properties that reflects seismic waves.

An opening in the crust that has allowed magma to reach the surface. There are three major types of volcanoes, a shield volcano that has a low dipping angle because of the molten material being more ...

array

Earth science; Seismology

An ordered arrangement of seismometers or geophones, the data from which feeds into a central receiver.

two-station method

Earth science; Seismology

Another approach to measuring group and phase velocities using two stations lying on the same great-circle path.

rigidity

Earth science; Seismology

An index of the resistance of an elastic body to shear. The ratio of the shearing stress to the amount of angular rotation it produces in a rock sample.
