That confusion aside, any newcomer to a science faces a lahar (p. 172) of jargon, rarely glossarized and one that swiftly buries the unfortunate student.
Examples include avalanches, haboobs, seafloor turbidity currents, lahars, pyroclastic flows, and lava flows.
Melting snow and ice, intense rainfall or the breakout of a summit crater lake can all generate lahars.
A lahar's viscosity decreases with time, and can be further thinned by rain, but it nevertheless solidifies quickly when coming to a stop.
The lahar and flood destroyed six mostly not-yet-occupied summer ranch houses.
Large volcano-associated debris flows known as lahars pose a threat to populated areas downstream from glaciated volcanoes.
A lahar can cause fatalities years after its precipitating eruption.
Lahars have the consistency, viscosity and approximate density of concrete: fluid when moving, solid at rest.
