gouge
Earth science; Seismology
Crushed, sheared, and powdered rock altered to clay. Usually found within the fault zone itself.
tensional (T) axis
Earth science; Seismology
In a double-couple system, the dipole that is directed outer from the source and found in the compressional quadrant of a focal mechanism. The ground is being pulled away from ...
wavefront
Earth science; Seismology
Imaginary surface or line that joins points at which the waves from a source are in phase (e.g., all at a maximum or all at a minimum).
basement
Earth science; Seismology
Igneous and metamorphic rocks that underlie the main sedimentary- rock sequences of a region and extend downward to the base of the crust.
tesseral harmonic
Earth science; Seismology
Higher order surface spherical harmonics combining latitudinal and longitudinal nodal patterns.
soil amplification
Earth science; Seismology
Growth in the amplitude of earthquakes when seismic waves pass from rock into less rigid material such as soil.
