Pyroclastic flows are hot, turbulent, flows of gas, pumice, rock debris and ash, often produced during major explosive volcanic eruptions. Researched events have been relatively small volume. Only 2 very large volume examples have been documented in detail, but these have some anomalous characteristics. This multi-pronged research (remote sensing, mapping, sampling, geochemistry, volatile analyses, vesicularity studies, petrography, and experimental flow studies) will investigate 3, >1,000 km3 deposits in the Andes, South America, to clarify the eruption and flow processes of large volume flows, which are a greater hazard than the recent Indian Ocean tsunami event.
