Which outcome occurs when prolonged pyroclastic flows destabilize slopes?

💡 Explanation

Lahar generation happens because intense pyroclastic deposition saturates slopes with debris. This saturation reduces friction via a fluidization mechanism, therefore heavy rainfall mixes with sediment to create lahars, rather than producing other volcanic landforms or atmospheric changes.
