Summary:In a facility similar to a shock tube, cylindrical samples of Mount St Helens vesicular dacite (diameter 17 mm, length 50 mm) were experimentally subjected to T (up to 950°C) and P (up to 200 bar) corresponding with those in highly viscous lava domes. This high-T/high-P section of the tube was separated from a low T/low-P section by a diaphragm which, when removed, caused rapid decompression and consequent fragmentation of the dacite. These pyroclasts were photographed in flight and collected for physical characterization. [E.H.F.]
