Hydrovolcanic Eruptions and Volcanic Processes Involving External Water
Session ID#: 73973
Session Description:
Almost 30% of eruptions are classified as hydrovolcanic, where magma interacts explosively with external water, resulting in a more intense eruption. However, further study of the dynamics and products of magma-water interactions is needed, and in addition we need an understanding of the availability of groundwater prior to, during, and after hydrovolcanic eruptions. Additionally, when external water interacts with volcanic products, secondary hazards are possible, such as lava-water mixing, fragmentation, and explosive ejection during ocean entry or the melting of volcano summit snow or ice, that can result in lahars or jökulhlaups. Therefore, this multi-disciplinary session includes work on the dynamics and deposits of (1) hydrovolcanic eruptions, such as phreatomagmatic, littoral or subaqueous eruptions, and (2) other volcanic processes involving external water, such as the development of hydrothermal systems, peperites, hyaloclastites, lava deltas, and lahars. Contributions are encouraged from all related fields, including: physical volcanology, planetary science, and geomorphology.
