Definitions:

Pyroclastic Flow

A fast-moving current of hot gas and volcanic materials (ash, lava fragments) that flows down the sides of a volcano during an explosive eruption.

Lahar

Composite Volcanoes

Volcanoes constructed from multiple layers of lava flows, volcanic ash, and other volcanic debris, characterized by steep profiles and periodic explosive eruptions.

Lahars

Volcanic mudflows or debris flows that occur when volcanic materials become saturated with water and rapidly move down slopes.
