← GeographyWhich consequence results when pyroclastic damming collapses during eruptions?
A)Increased lahar formation downstream✓
B)Elevated stratospheric sulfur aerosols
C)Decreased local geothermal gradients
D)Enhanced silicate mineral weathering
💡 Explanation
Increased lahar risk happens because water entrainment via pyroclastic dam failure causes debris flow, therefore downstream regions will experience massive mudflows rather than aerosols, geothermal reduction, or weathering.
