Seismology

poisson distribution

Earth science; Seismology

A probability distribution that characterizes discrete events occurring independently of one another in time.

A term used in exploration seismology refer to surface waves generated from explosions. They are characterized by low velocity, low frequency, and high amplitude, and are observed in regions where ...

seismometer or seismograph

Earth science; Seismology

A seismometer is a damped oscillating mass, such as a damped mass-spring system, used to detect seismic-wave energy. The motion of the mass is commonly transformed into an electrical voltage. The ...

seismic moment tensor

Earth science; Seismology

A mathematical representation of a full set of solutions to produce a wide variety of effective source deformations and time histories.

anisotropy

Earth science; Seismology

A material where the stress-strain behavior depends on the orientation of the sample.

active fault

Earth science; Seismology

A fault along which slip has occurred in recent geological time, or where earthquake foci are located.

aliasing

Earth science; Seismology

A phenomena where frequencies are overlapping each other, and the the individual contributions from those frequencies are unable to be deciphered. This is avoided by decreasing the sampling interval ...
