Which risk increases near a volcano with a silica-rich lava dome growing within its caldera?

A)Increased frequency of pyroclastic flows✓

B)Higher incidence of lahars downstream

C)Greater risk of glacial outburst floods

D)Increased prevalence of carbon sequestration

💡 Explanation

Pyroclastic flow risk increases because a silica-rich lava dome's blocky material destabilizes, leading to dome collapse events and creating pyroclastic flows; therefore, A is correct, rather than other options like lahars which require water interaction.
