'''Seismology''' (from the [[Greek language|Greek]] ''seismos'' = earthquake and ''logos'' = word) is the scientific study of the movement of waves through the [[Earth]], as a result of natural or man-made activity. The field includes studies of earthquakes and similar variants  as ''seaquakes'', activities of volcanoes, landslides and movement caused by [[tectonic plates]].

Earthquakes (and other earth movements) produce different types of [[seismic wave]]s.  These waves travel through the earth (soil and rock), and provide an effective way to "image" or "see" events and structures in the Earth's subsurface.
