Seismology (; from Ancient Greek σεισμός ( seismós ) meaning
"earthquake" and -λογία ( -logía ) meaning "study of") is the scientific
study of earthquakes (or generally, quakes) and the propagation of elastic
waves through the Earth or other planetary bodies. It also includes studies of
earthquake environmental effects such as tsunamis as well as diverse seismic
sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric,
and artificial processes such as explosions. A related field that uses geology
to infer information regarding past earthquakes is paleoseismology. A
recording of Earth motion as a function of time is called a seismogram. A
seismologist is a scientist who does research in seismology.
