← GeographyWhich outcome frequently destabilizes surrounding regions because of volcanism within volcanic arcs?
A)Pyroclastic density current induced jokulhaups✓
B)Deep sea trench methane clathrate destabilization
C)Orogenic lifting feedback acceleration
D)Oceanic hydrothermal vent cessation
💡 Explanation
Pyroclastic flows can melt glacial ice causing significant jokulhaups (glacial outburst floods); because the mechanism is rapid melting and release of water, surrounding areas are flooded. Jokulhaups, rather than other listed geological effects, are linked to hazards affecting broad areas.
