Session V009 "Eruptive processes and watery hazards of 'wet' volcanoes on land, in the sea or under ice
Water in oceans, glaciers, lakes, streams and aquifers lies in the path of magma ascending to eruption over the great majority of Earth, and on some other planets as well. In addition to pressure effects of eruptions under water or ice, water thermally affects magma during effusion or fragmentation and strongly modifies particle transport. This can produce phenomena that include edifice collapse resulting from persistent hydrothermal alteration, sudden discharges of water from hydrothermal systems, precipitation-related collapses, hydrothermal eruptions without clear precursors, and debris flows and lahars triggered by crater-lake outbreaks. We invite contributions on all aspects of water-magma interaction and hazards resulting from them, including contributions on submarine volcanism, volcanism in lakes, phreatomagmatic eruptions, subglacial volcanism, subsurface interactions of dikes and conduits with country-rock groundwater, the behavior/evolution of hydrothermal systems, hydrothermal explosions, and water’s role in volcano structural instabilities and the formation and emplacement of avalanches and lahars.
Invited presentations for this session are:
*Rebecca Carey et al. " Exploration and geological mapping of the volcanic architecture and 2012 silicic eruption deposits of the Havre submarine volcano, Kermadec Arc, New Zealand"
*Carol Finn "Identifying water on Mt. Baker and Mt. St. Helens, WA with geophysics: implications for volcanic landslide hazards"
*Michael Ort et al. " Water, water, everywhere: The 2008 Okmok eruption, Alaska"
*Hannah Reynolds & MT Gudmundsson "Subglacial eruptions and enhanced geothermal activity during the 2014 Bardarbunga eruption, Iceland"
