deconvolution

Earth science; Seismology

The inverse of convolution. Used in extracting information (e.g. source-time function, instrument response) from the raw seismic data to retain the source signal or ground displacement.

The instantaneous boundary between the slipping and locked parts of a fault during an earthquake. Rupture in one direction on the fault is referred to as unilateral. Rupture may radiate outward in ...

core

Earth science; Seismology

The innermost layers of the Earth. The inner core is solid and has a radius of about 1300 kilometres. (The radius of the Earth is about 6371 kilometres. ) The outer core is fluid and is about 2300 ...

shadow zone

Earth science; Seismology

The area on the Earth's surface protected from seismic wave arrivals.

earthquake

Earth science; Seismology

The sudden release of stored elastic energy caused by the sudden fracture and movement of rocks along a fault. Some of the energy released is in the form of seismic waves, that cause the ground to ...
