lurching of the ground
Earth science; Seismology
Disruption of soil by lateral spreading under gravity.
gutenberg discontinuity
Earth science; Seismology
Discontinuity in seismic velocity that marks the boundary between the core and the mantle; named after seismologist Beno Gutenberg.
eigenfrequencies
Earth science; Seismology
Discrete frequencies of motion that satisfy the boundary conditions of a mode.
longitudinal waves
Earth science; Seismology
Displacement associated with far-field P-waves in a homogeneous isotropic solid is parallel to the direction of propagation (e.g. P-waves).
Gutenberg discontinuity
Earth science; Seismology
Discontinuity in seismic velocity that marks the boundary between the core and the mantle; named after seismologist Beno Gutenberg.
surface faulting
Earth science; Seismology
Displacement that reaches the Earth's surface during slip along a fault. Commonly accompanies moderate and large earthquakes having focal depths less than 20 km. Surface ...
far-field term
Earth science; Seismology
Decays slowly, dominating displacement at large distances and disproportional to the time derivative of the reduced displacement potential, that is if there is a step in the ...
