Question

Quizplus · Accepted Answer

Lahars are dangerous because they are mixtures of volcanic ash, rock debris, and water that flow down from a volcano. Hot pyroclastic material from an eruption can melt snow and ice on the volcano, combining with the ash and debris to create a fast-moving mixture that can travel long distances and cause significant damage to infrastructure, property, and lives.
