Which slope failure risk significantly increases when permafrost thaws initiating solifluction processes in arctic regions?

💡 Explanation

When permafrost thaws, the active layer's water saturation increases and its shear strength decreases accelerating solifluction because gravitational forces exceed the soil's resistance. Therefore amplified soil creep results, rather than avalanches, weathering, or seismicity which involve entirely distinct mechanisms and geological contexts.
