Which risk increases when glacial meltwater outburst interacts?

💡 Explanation

Increased debris flow risk occurs due to enhanced **slope destabilization**. Meltwater saturates volcanic ash deposits, reducing shear strength, because of increased pore pressure; therefore volcaniclastic flows increase, rather than other hydrogeological changes.
