Answer:
Flows and surges may be very hot (several hundred °C) and can start fires. Some are cooler and can deposit sticky wet mud. Pyroclastic flows and surges are the most destructive of all volcanic activity.
Explanation:
hope it helps
Pyroclastic flows and surges are the most destructive of all volcanic activity. People caught in the direct path of a flow are unlikely to survive.
Pyroclastic flows can kill people up to a distance of six to nine miles (10-15km) from the volcano. Lahars are among the most far-reaching phenomena, with deadly effects over a mean distance of more than 12.5 miles (20km).
