Which consequence results when pyroclastic flows rapidly melt glaciers?

💡 Explanation

Pyroclastic flows generate jokulhaups via catastrophic melting; therefore, substantial outburst floods are the result, because the sudden addition of meltwater forms large rapidly-moving volumes, rather than gradual changes in glacial dynamics or mineral composition.
