Which risk abruptly escalates when water seeps into degassing cracks of a lava dome?

💡 Explanation

Introduction of water can flash to steam, increasing pressure inside the dome. This is the **phreatomagmatic explosion** mechanism releasing pyroclastic flows because rapid heat transfer occurs, therefore the risk of flows increases, rather than other gradual processes such as lake level.
