Which hazard sharply increases during lava dome growth?

💡 Explanation

Pyroclastic flows are a major hazard during lava dome growth because increasing instability leads to dome collapse causing a release of trapped gases and hot rock as block-and-ash flows; therefore it increases, rather than tremor or downwarping, which are less directly linked.
