poisson distribution
Earth science; Seismology
A probability distribution that characterizes discrete events occurring independently of one another in time.
ground roll
Earth science; Seismology
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 ...
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 ...
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 ...
