Which risk increases when tephra dams fail during volcanic activity?

💡 Explanation

Tepra dams may form after the eruption causing temporary blockades; dam failure causes a rapid release of water and sediment. This increases debris flow rates because the increased water content mobilizes volcanic ash and debris in a lahar, rather than bioremoval.
