Detailed Description
When molten lava encroaches on grassland, forests, or other vegetated land, subsurface pockets of natural gas from the burning plant material can ignite, causing a blast known as a "methane explosion." To avoid this hazard, keep a safe distance—at least tens of yards—from the margin of an active lava flow in vegetated areas.
