Question

Quizplus · Accepted Answer

The principal difference between a lahar and a mudflow is that a lahar contains pyroclastic debris from a volcanic eruption, while a mudflow does not necessarily contain volcanic material. Additionally, lahars are often triggered by volcanic activity, whereas mudflows can be triggered by a variety of factors, such as heavy rainfall or dam failure. Grain size and shape of the path taken by the moving mass are not the main distinguishing factors between lahars and mudflows. The idea that lahars contain abundant water while mudflows are dry is also not accurate, as both types of flows can contain water, mud, and debris.
