Which risk predominates slope failure in mountainous regions with thawing permafrost?

💡 Explanation

When permafrost thaws, the ice that cements soil and rock together melts, causing sediment liquefaction, because water saturation reduces intergranular friction, accelerating creep processes. Therefore, creep dominates; alternatives need different changes: reduced vegetative cover causing more surface erosion, water accumulation increasing rockfall and ice base destabilization causing glacier advance.
