← GeographyWhich hazardous outcome dramatically increases after pyroclastic flows destabilize steep volcanic slopes?
A)Catastrophic debris avalanche formation.✓
B)Regional methane hydrate release.
C)Sudden stratospheric ozone depletion.
D)Enhanced thermohaline circulation disruption
💡 Explanation
Pyroclastic flows deposit weakly consolidated material on unstable slopes, and increased mass loading triggers slope failure via increased shear stress; therefore, debris avalanches become much more likely, rather than ozone depletion from volcanic gasses, which are independent.
