Which event develops when an eruption's gas pressure decreases mid-flow?

💡 Explanation

Subsidence occurs primarily because decreased exsolved gas during pahoehoe flow causes crustal cooling and contraction initiating inflation feature creation through differential degassing, therefore, forming tumuli and pressure ridges, rather than causing increased lahar risk.
