The working group (W.G.) will address basic problems and unanswered questions in the realm of explosive volcanism and its products. Its primary functions are the organization of field and laboratory consortia, formal meetings, and the editing of special publications. Through these means we propose to stimulate research and communication on explosive volcanism.
The W.G. has three main areas of interest: (1) pyroclastic deposits, including characterization, stratigraphy and tephrochronology; (2) eruption mechanisms nd eruption dynamics, including geochemical and geophysical studies, modeling of volcanic systems and depositional processes, and fluid dynamics (much of this work can be applied to volcanic hazard analysis); and (3) interaction of explosive eruptions and the atmosphere.
