Which risk increases during rapid snowmelt in mountainous permafrost regions experiencing solifluction?

💡 Explanation

During rapid snowmelt, increased water saturation in the active layer overlying permafrost reduces soil shear strength initiating or accelerating solifluction, causing slope instability and mobilizing saturated soil. Therefore increased debris flow frequency occurs, rather than altered coastal erosion, thermal conductivity, or methane which relate to other specific environmental conditions.
