Which outcome occurs when subsurface pressure exceeds summit vent capacity during slow lava dome growth?

💡 Explanation

Localized pyroclastic flow will be generated because over-pressurization leads to explosive lateral dome collapse, driven by volatile exsolution; therefore pyroclastic surge occurs, rather than simple exfoliation controlled by weathering processes alone.
