Quizplus · Accepted Answer

Pyroclastic flows and lahars are both extremely fast-moving and deadly volcanic hazards that can reach speeds of up to 700 km/h (430 mph). Trying to outrun them on foot is not a viable option, as they can cover large distances in just a few minutes. It is generally recommended to evacuate as soon as possible if you are in the path of these hazards.
