[NOTE: Sessions NHO4 and V27 were combined into one session] NH04: Hazards Associated With Snow- and Ice-Capped Volcanoes

Interactions between glacial ice and/or snow and volcanism can lead to uniquely hazardous phenomena (e.g., lahars and debris avalanches), and distinctive volcanic landforms. Recent activity in Alaska, the Cascades, and Iceland have highlighted the importance of understanding explosive and effusive eruptions from snow and ice covered volcanoes. We invite contributions focused on volcanic hazards influenced by snow/ice. Contributions can address any aspect of such interactions, including deposits formed, physics of lava-ice/snow interactions, geomorphology of snow/ice-capped volcanoes, inventories of ice thicknesses at active/dormant volcanoes, atmospheric patterns and potential ash distribution, and hazard mapping.

[NOW Combined with NHO4] V27: Magma-Ice-Meltwater Interactions: Physical Processes and Implications for Volcanic Hazards

Magma-ice interactions may greatly influence the style, duration, and products generated during eruptions at ice and snow clad volcanoes. External water from ice melt plays a key role in the eruptive process and may exacerbate the explosive component of an eruption. Meltwater may initiate other hazardous phenomena, such as outburst flooding and lahars. Our goal in this session is to bring together scientists engaged in studies of magma-ice interaction who are focused on the physical processes and hazards posed by these interactions. We are particularly seeking new results and perspectives from field, laboratory or theoretical studies of recent eruptions involving magma-ice interactions.

EGU General Assembly: GMPV12 Glaciovolcanism as a climate proxy: progress and problems

Vienna, Austria, 2-7 May 2010

This session seeks contributions that present field, analytical and/or theoretical studies using glaciovolcanism as a climate or environmental proxy. We especially encourage contributions describing new isotopic dating methods or protocols that can yield sub-glacial-cycle age-precision for Miocene to Pleistocene eruptions, particularly for basalts; new and/or improved compositional proxies that can identify a glacial eruptive setting; examples of palaeo-ice thickness estimates from field and/or volatile measurements; and results of well-developed palaeoenvironmental case studies, including studies of erosional histories that document extent of edifice modification by post-eruption glaciations. By showcasing these field- and laboratory-based advances at EGU, we hope to raise the profile and further establish the application of glaciovolcanism as a mainstream palaeoclimatic proxy methodology of similar credibility and utility as more orthodox methods, such as studies of glacigenic sediments.

Conveners: Ben Edwards and John Smellie
