Glaciovolcanism: Recent Advances in Understanding the Interaction of Glaciers and Volcanoes
Session ID#: 72938
Session Description:
Ice-capped volcanoes can be found all over the Earth as well as on extra-terrestrial bodies. Interactions between glaciers and volcanoes have generated a wide range of hazards, including lava flows, ash plumes, pyroclastic density currents, lahars, and glacial outburst floods. However, these interactions remain poorly understood due to the remoteness of glacio-volcanic regions. Thus, there is a present need for an integrative session to stimulate the discussion of processes and implications of volcano-ice interactions.
We invite contributions that include new observations and interpretations from studies of current, recent and past glaciovolcanism on Earth and other planetary bodies. Research from a wide spectrum of fields will be welcome, including but not limited to: hazard mitigation, geophysical studies, experimental and numerical simulations, field outcrop studies, and remote sensing observations.
