Laplacian
Earth science; Seismology
Is the divergence of the gradient (see divergence and gradient).
Hooke's Law
Earth science; Seismology
Is an empirical relationship expressing a linear relationship between stress and strain.
near-field term
Earth science; Seismology
Involves displacements directly proportional to the reduced displacement potential and decay rapidly. If there is any step in the effective pressure a permanent deformation of ...
Stonely waves
Earth science; Seismology
Interface waves with the largest amplitudes confined to the neighborhood of a plane interface of two elastic media.
covariant matrix
Earth science; Seismology
Indicates the uncertainty in the model due to both the nature on the inverse problem and the errors in the observations.
evanescent wave
Earth science; Seismology
A P-wave that is "trapped" propagating along the free surface. This type of wave decays exponentially with depth.
homogeneous (material)
Earth science; Seismology
A material that has the same composition throughout.
