Abstract
Pyroclastic flows are volcanically produced hot, gaseous, particulate density currents. Their deposits offer unparalleled opportunities to estimate minimum volumes of near-surface magma chambers as well as vertical chemical, mineralogical, and thus temperature and pressure distributions within the magma columns immediately prior to eruption. The modes of origin and transport of pyroclastic flows have been the subject of intense debate ever since the 1902 eruption of Mt. Pelée produced nuées ardentes which destroyed the town of St. Pierre. Because pyroclastic flows are emplaced rapidly and may flow for long distances, they are particularly useful for intrabasinal correlations.
