Pyroclastic flows are fast-moving, highly destructive avalanches of hot rocks, ash, and gas that can reach speeds of up to 450 miles per hour. These flows are typically generated during explosive volcanic eruptions when magma, gases, and other volcanic materials rapidly expand and burst through the volcano's summit. They are a significant hazard to nearby human populations and can cause devastation over large areas, burying everything in their path. Pyroclastic flows can travel for several kilometers from the volcano, causing widespread destruction and loss of life. It is crucial for authorities to monitor volcanoes closely and evacuate nearby areas when signs of an impending eruption are detected.
