Which hazard increases due to gas pressure under solidified lava?

💡 Explanation

Explosive eruption initiation increases, because gas trapped beneath a solidified lava dome experiences **pressure accumulation**, stressing the overlying solidified crust, therefore triggering sudden eruptions, rather than magma convection changes dependent on buoyancy.
