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.
volcano
Earth science; Seismology
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 ...
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.
