Description [edit]. Lahar is a Javanese word that describes volcanic mudflows or debris flows. Lahars have the consistency, viscosity and approximate density of wet concrete: fluid when moving, solid at rest.Lahars can be huge.ahars have several possible causes: 1  Snow and glaciers can be melted by lava or pyroclastic flows during an eruption. 2  Lava flows out of open vents and can mix with wet soil and mud on the slope of the volcano making a very viscous, high energy lahar. 3  A flood caused by a glacier, lake breakout, or heavy rainfall can release a lahar, also called ....
- When magma reaches the surface it is called lava (pronounced 'larver'). If the level of lava in the crater overflows the rim, it will begin to flow down the sides of the volcano. Different types of lava are more runny than others. and the most runny types can flow down the volcano at over 30 miles per hour. composite volcano is also commonly called a stratovolcano. These volcanoes usually form in subduction zones. Stratovolcanoes form on the continental side of a subduction zone where the melting oceanic crust forms pools of molten rock in a magma chamber.
