Which risk increases when degassing pathways become blocked within a volcanic dome?

💡 Explanation

Over-pressurization increases because blocked degassing forces gas accumulation within the dome, thereby raising internal pressure until it surpasses the dome's structural strength, which causes explosive eruptions, rather than merely altering viscosity.

• Which risk increases for communities protected by artificial levees during intense, prolonged rainfall events?
• Which effect occurs when sustained offshore winds drive coastal upwelling of nutrient-rich water?
• Which erosion event results from high pore liquid pressure in sediments on steep volcanic slopes?
• Which process initiates island arc formation when oceanic lithosphere converges?
• Which outcome happens when thermal gradients near ocean streams produce high pressure cells?
