Lahars form 1) from debris avalanches that contain water from snow and ice which, when released, mixes with loose debris to form a lahar, 2) from pyroclastic flows and surges which release water that mixes with debris, 3) from pyroclastic flows which dilute themselves with river water as they travel downslope,

Lahar is an Indonesian term for a volcanic mudflow. These lethal mixtures of water and tephra have the consistency of wet concrete, yet they can flow down the slopes of volcanoes or down river valleys at rapid speeds, similar to fast-moving streams of water.

Lahar is an Indonesian word describing mudflows and debris flows that originate from the slopes of a volcano. the Electron Mudflow has been dated at 530 Carbon-14 years B.P. This lahar, which evidently began as a failure of part of the western edifice, has not been correlated with any eruptive activity at Mount...

The lahars seemed to diminish a year after the 1991 eruption, and people returned to the village. But in the summer of 1994, high up the river valley that runs down the side of Mt. Pinatubo toward San Antonio, a lahar cut off a segment of the Pasig-Potrero River behind a dam of loose volcanic debris.
