Examples

“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.”
