Which risk increases when a rhyolitic lava dome exhibits block faulting?

💡 Explanation

Magmatic volatile depressurization increases because block faulting fractures the dome, reducing pressure, leading to explosive eruptions; therefore, depressurization risk rises, rather than effusive flow or indirectly lahar generation or hydrothermal cooling alone.
