Pyroclastic flow would have the most far-reaching impact on humans, as it is a fast-moving cloud of hot gas, ash, and other volcanic materials that can travel hundreds of miles away from the eruption. Pyroclastic flows are extremely destructive and can cause significant damage to anything in their path, including homes, infrastructure, and vegetation. Additionally, they can trigger secondary hazards such as tsunamis and lahars (mudflows), which can further impact communities far from the volcanic eruption site.
