A downslope viscous flow of fine-grained materials that have been saturated with water, moving under the pull of gravity.
As nouns the difference between lahar and earthflow
is that lahar is lahar (volcanic mudflow) while earthflow is a downslope viscous flow of fine-grained materials that have been saturated with water, moving under the pull of gravity.lahar
English
(wikipedia lahar)Noun
(en noun)- Such a highly destructive mud-flow (termed a lahar ) eventually stops as a pile of debris of all shapes and sizes, as mixed up as a glacial moraine; the two deposits have often been confused.
- Pyroclastic flows are often difficult to distinguish in outcrops from a similar type of fragmental debris flow known as lahars'''''. Both are characteristically unstratified and unsorted. A deposit containing blocks of varied compositions with rounded shapes is more likely to have been formed by a ' lahar than by a glowing avalanche.
- A regime of persistent lahar activity results when eruptive activity continually supplies unconsolidated volcanic material for remobilization.
