Which outcome results when volcanic vent instability causes increased mass flow?

💡 Explanation

A destabilized volcanic vent causes a lateral blast eruption because vent collapse reduces confining pressure, triggering explosive decompression, therefore intensifying the sideways ejection of material rather than purely vertical eruption phases.
