Which hazard reduction results when controlled degassing vents penetrate viscous lava domes?

💡 Explanation

Reduced over-pressurization arises from controlled gas release through increased permeability, because pressure cannot build to explosive levels. Thus, the likelihood of rapid dome collapse decreases, rather than enhancing cooling or changing chemical properties of magma via crystal nucleation or chemical treatments.
