higher-modes
Earth science; Seismology
Secondary frequencies generated that have one or more nodes of zero motion (see also Fundamental mode).
turbidites
Earth science; Seismology
Sea-bottom deposits formed by massive slope failures where rivers have deposited large deltas. These slopes fail in response to earthquake shaking or excessive sedimentation load. The temporal ...
tomographic
Earth science; Seismology
Construction of the image of an internal object or structure (in 3-D) from measurements of seismic waves at the surface.
tomography
Earth science; Seismology
Construction of the image of velocity variations inside the Earth from measurements of seismic waves at the surface.
source-time function
Earth science; Seismology
Contain all of the information available on the details of the earthquake rupture (e.g. duration of rupture, directivity effects, moment release).
inner core
Earth science; Seismology
Central solid region of the Earth's core, probably mostly iron; radius is about 1221 kilometers, discovered by Inge Lehmann in 1936.
island arc
Earth science; Seismology
