Lahar 10
Lahar 10 : Landslide or mudflow of pyroclastic material on the flank of a volcano; deposit produced by such a landslide. Lahars are described as wet if they are mixed with water derived from heavy rains, escaping from a crater lake or produced by melting snow. Dry lahars may result from tremors of a cone or by accumulating material becoming unstable on a steep slope. If the material retains much heat, they are termed hot lahars. (AGI)
