Which outcome occurs when lahar flows destabilize steep topography?

💡 Explanation

Lahar flows saturate and weaken slopes, initiating a rotational slide due to increased pore water pressure, and this mass wasting often leads to the formation of debris avalanche scars; therefore, the avalanche occurs, rather than more subtle processes.
