Abstract

A program of temperature studies of the eruptive products of Mount St. Helens was established May 20, 1980, just 2 days after the catastrophic eruption of May 18. In general, the more recent deposits were emplaced at higher temperatures than the earlier ones. Emplacement temperatures of deposits of the debris avalanche of May 18 ranged from about 70 to 100 deg C, of the directed blast of May 18 from about 100 to 325 deg C (depending on azimuth from the vent), and of the subsequent pumiceous pyroclastic flows from about 300 to 850 deg C. Temperatures of the summit domes were as high as 897 deg C.
