Seismology
attenuation
Earth science; Seismology
The reduction in amplitude of a wave with time or distance travelled.
accelerogram
Earth science; Seismology
The record from an accelerograph showing ground acceleration as a function of time.
slowness
Earth science; Seismology
The reciprocal of velocity. Most seismic tomography methods involve subdividing the medium into blocks and solving for slowness perturbations that cause the predicted times to match observed times ...
poles and zeros
Earth science; Seismology
The real and complex solutions to the instruments transfer function. Used in removing the instrument response from the signal.
Young's modulus (E)
Earth science; Seismology
The ratio of tensional stress to extensional strain along the axis where the tension was applied.
shear modulus
Earth science; Seismology
The ratio of shear stress to shear strain of a material during simple shear.
