Which risk increases significantly due to blocked vent viscous lava?

💡 Explanation

Pyroclastic flow intensity magnifies because pressure builds behind the lava dome, undergoing violent fragmentation. This is explosive decompression, therefore leading to a stronger lateral blast rather than caldera formation from broad magma removal.
