Modern Description

written by Susanne M Hoffmann

Earthquakes are caused by motions of pieces of the Earth's crust. In most cases, they are caused by plate tectonic, i.e. by one continental plate moving towards another one. However, also (volcanic) eruptions might be accompanied by earthquakes. The reason can be an explosion of material (e.g. if a mountain top is blown away by an eruption). Still, volcanic activity is - in most cases - also caused by motion in the plate tectonic. Therefore, the volcano and the earthquake typically have the same cause and the volcanic eruption "only" amplifies the earthquake instead of being direct cause of it.
