Pyroclasts refers to ash, rock fragments and volcanic bombs ejected during volcanic eruption. When pyroclasts mix with super-heated gases ejected during volcanic eruption, this results in pyroclastic flow. Pyroclasts may then mix with water as it flows down the volcano.

NOTE: pyroclasts refers to ash
