Following heavy tephra deposition, which outcome becomes increasingly likely due to changes in load distribution?

A)Glacial isostatic rebound acceleration

B)Increased permafrost methane emission

C)Localized slope instability increase✓

D)Accelerated orographic precipitation decrease

💡 Explanation

Tephra deposition increases the overburden stress on slopes, driving instability because the mechanism is a reduction in the safety factor of slopes. This leads to landslides; therefore, answer C is appropriate rather than rebound or changing emissions that relate less predictably to the redistribution of material and stress.
