← GeographyWhich volcanic risk escalates because of pyroclastic density?
A)Increased lateral blast devastation range✓
B)Diminished lahar initiation probability
C)Reduced atmospheric aerosol concentrations temporarily
D)Decreased downstream sediment deposition volume
💡 Explanation
Lateral blast devastation increases via momentum transfer due to pyroclastic flow density; because the kinetic energy rises sharply with density given constant velocity, therefore blast power amplifies rather than alternative attenuations by atmosphere or friction.
