After prolonged tephra fall, which hazard increases because of landscape destabilization?

💡 Explanation

Debris flow risk rises because tephra deposition causes sediment loading, leading to slope instability via gravitational force overcoming friction. Therefore surges are expected, rather than albedo changes, because deposition directly influences hydrology and stability.
