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 ....
The only way to absolutely know that the flows you're looking at are pillow lavas rather than pahoehoe toes, is to find submarine sediments (such as hyaloclastite debris formed from the violent reaction of lava and water) between the pillows.
