Which post-eruption outcome is initiated by pyroclastic flow deposition?

💡 Explanation

Lahars form when heavy rainfall mobilizes pyroclastic debris, because the loose material readily mixes with water, creating a dense mudflow; therefore, sediment bulking occurs, rather than lithification that requires much longer consolidation, or glacier growth that's tied to cooler climatic conditions.
