6-6-6-6-6-6-6-6-6-6-6-6-6 From: Thomas Jones <thomas.jones@xxxxxxxx> Dear Colleagues, We would like to invite you to submit your abstract to session S1.23 â??Fissures and fountains: processes and productsâ?? at the next Cities on Volcanoes 11 conference (Heraklion, Crete, 23-27 May 2020). Abstract description: Fissure eruptions initiate as curtains of lava fountains often several hundred meters to a few kilometres in length. The eruptive fissure geometries are initially of high aspect ratio, and may involve multiple vents connected at depth, but appearing segmented and separated at the surface. Over the order of hours to weeks, the curtain often focuses to one main point along the fissure. This dynamic evolution makes hazard monitoring and mitigation challenging. A continuous spectrum from explosive (e.g. fountaining) to effusive (e.g. lava flows) behaviour exists, and occasionally a single vent can transition in behaviour or display two variants simultaneously. Furthermore, the spatial and temporal variations in eruptive style produce highly variable deposits (typically including spatter bombs, scoria, lapilli, and peleâ??s hair). Recent eruptions such as the 2018 eruption of Kilaueaâ??s Lower East Rift Zone have highlighted the extreme variably of these eruptions and the challenges they pose to society. This session welcomes contributions that cover any aspect of fissure eruptions. These topics include, but are not limited to, monitoring techniques, hazard management, magma storage and transport, eruption dynamics, and associated long-term impacts. Looking forward to seeing you all in Crete! 6-6-6-6-6-6-6-6-6-6-6-6-6 ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
