Which risk significantly escalates following lava crystallization crust formation?

💡 Explanation

Gas pressure increases because crystallization and crust formation constricts gas escape, intensifying vesiculation. This creates overpressure and potential explosions, therefore increasing explosive events rather than basalt fracturing, ocean effect or flow heat transfer.
