Which ground response risk sharply rises along arctic shorelines underlain by shallow permafrost and unstable terrain heated by warmer seawater?

💡 Explanation

Increased seawater temp melts permafrost triggering solifluction, a soil creep enhanced by thaw slumps, because active layer saturation rises. Thus, soil fails; rather than fault motion or lake formation, shallow coastal permafrost melts releasing built-up stresses.
