Which risk escalates inside deep canyons cutting through pyroclastic deposits?

A)Increased lahar hazard after heavy rain✓

B)Higher geothermal gradient fluctuations locally

C)Elevated CO₂ emissions due increased weathering

D)Reduced landslide threat due to consolidation

💡 Explanation

Lahar formation increases after heavy rains because the Infiltration Excess Overland Flow mechanism rapidly saturates unstable pyroclastic material along steep canyon walls; therefore, lahars form easily down-canyon, rather than water slowly filtering stabilising the slopes.
