Which risk significantly escalates as degassing pathways become blocked inside a growing lava dome?

💡 Explanation

When degassing pathways are blocked, gas pressure accumulates because the volatile gases cannot escape freely through the vent; therefore, the risk of an explosive eruption escalates, rather than experiencing a more gradual lava flow.
