Which volcanic event increases after lava dome collapse?

💡 Explanation

Increased pyroclastic density current frequency follows dome collapse due to increased exposure area available for gravitational collapse and gas release to generate density currents; rather than affecting lava viscosity, shield subsidence rates or rock crystallization, because the mechanism is gravitational instability.
