Seismology
Seismology
Seismology (pronunciation: /saɪzˈmɒlədʒi/ or /saɪsˈmɒlədʒi/) is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. The field also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, 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.
Etymology
The word "seismology" is derived from two Greek words, seismos (σεισμός), meaning "earthquake", and -logia (-λογία), meaning "study of".
