3-3-3-3-3-3-3-3-3-3-3-3-3 From: "Beckett, Frances" <frances.beckett@xxxxxxxxxxxxxxxx> Dear Colleagues, We invite submissions to our session on â??Tephra Impacts: numerical modelling, field measurements and observations, hazard assessment and forecasting challengesâ?? at the IAVCEI 2023 Scientific Assembly in Rotorua, New Zealand. Session Description Tephra damages buildings, water and power supplies, it disrupts transportation (including aviation) and farming activities, and fine-grained ash poses a health risk to humans and animals. Additionally, ash can continue to pose a hazard for many years after an eruption as deposits are remobilized by the wind. Our ability to assess the hazards associated with tephra can be improved through the dedicated development of numerical modelling, observations and monitoring techniques (e.g. satellite retrievals, lidar, radar and acoustic data). We can then build resilience and preparedness by understanding the potential activity scenarios prior to an event; this requires comprehensive assessments of previous activity based on field studies and geophysical measurements, and the use of numerical modelling to determine the ensemble of possible scenarios. During eruptions real-time forecasting can benefit from data assimilation, using observations to initialize numerical models and validate predictions. We welcome contributions which present recent work aimed at improving our resilience to tephra impacts. In particular, we are interested in those studies which combine numerical modelling, geophysical monitoring and field observations. We are also interested in contributions which discuss forecasting strategies both prior to and during explosive eruptions. https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/__;!!IKRxdwAv5BmarQ!cIke7wxOPWilbck985kbhex3VYGU-wSGWpMpPbtvbUP6tQU-yKQe5HTsKcOtTMioC227VBtrfcwTh4di$ <https://urldefense.com/v3/__https://confer.eventsair.com/iavcei2023/__;!!IKRxdwAv5BmarQ!alQS3q2fGDnh0fvdtVoUDriw9IQRsTWv9fWrn22lINxRf6nKOGYuPZtEiMXDXxQ-N8NoJz93BmjHMSrP-8ML6LOcZouA4TIenA$> Abstracts are due by 2 September 2022 Kind regards, Frances Beckett, Sara Barsotti, Marco Pistolesi, Mike Pavolonis 3-3-3-3-3-3-3-3-3-3-3-3-3 ============================================================== 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).
