Seismology

Seismology (Greek seismos=earthquake and logos=study) 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. Seismology is a major component of Earth science.

History[edit | edit source]

The word seismology is derived from the Ancient Greek words seismos (meaning "earthquake") and -logia (meaning "study of"). The field of seismology was pioneered in the 19th century by scientists such as Robert Mallet, who is considered the father of seismology.

Types of seismic wave[edit | edit source]

Seismic waves are elastic waves that propagate in solid or fluid materials. They can be divided into body waves that travel through the interior of the materials; surface waves that travel along surfaces or interfaces between materials; and normal modes, a form of standing wave.

Measuring seismic waves[edit | edit source]

Seismic waves are studied by seismologists and geophysicists. Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer.
