Earth science; Seismology

An elastic wave in the Earth usually generated by an earthquake source or explosion.

seismic belt

Earth science; Seismology

An elongated earthquake zone, for example, circum-Pacific, Mediterranean, Rocky Mountain. About 60% of the world's earthquakes occur in the circum-Pacific seismic belt.

teleseism

Earth science; Seismology

An earthquake that is distant (usually more than 20 degrees) from the recording station.

preshock

Earth science; Seismology

An earthquake that occurs before the mainshock, but is not an unambiguous foreshock, either because it originated months or years before the mainshock or because it originated far from the epicenter ...
