A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. ... Volcanoes are often covered with ash and debris. Because of this, stratovolcanoes are known for causing deadly mudslides (sometimes called lahars). These can be the result ofvolcanic activity, earthquakes, or even rainfall.

The Andes range has many active volcanoes distributed in four volcanic zones separated by areas of inactivity. The Andean volcanism is a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate.
