Which consequence occurs the instant a lava dome collapses within a stratovolcano structure?

💡 Explanation

A pyroclastic density current results because the sudden decompression unleashes rapidly expanding gases and fragmented lava; therefore explosive lateral blasts occur, rather than ice melts, rain, or altered methane output, under common conditions.
