DESCRIPTION: The project will quantify the sizes and number densities of bubbles and microlites in pyroclasts; measure volatile concentrations in melt inclusions and groundmass glass to infer initial volatile content and degassing trends; estimate likely durations of magma ascent via volatile diffusion through embayments and crystals; construct numerical models of eruptive magma ascent, integrated with modeling of diffusive bubble growth to compare to observed bubble size distributions and degassing trends.
OUTCOMES: One journal publication has been published demonstrating previous explosive eruptions on Hawaii were fueled by a rapid decompression event and not higher gas content
