1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Britta Jensen <bjjensen@xxxxxxxxxxx> We are happy to announce a special session on tephra studies in honour of Don Mullineaux at this yearâ??s AGU. This is a general call for abstracts to a session that aims to embrace all multidisciplinary research that falls under the broad umbrella of tephra research - a reflection of Donâ??s considerable contributions. The details are: AGU Fall Meeting New Orleans 13-17 December 2021 Abstract open now, deadline August 4th Session Title: V022. Tephra, volcanic processes, and hazards: A session in honor of Don Mullineaux Session Description: This session honors the life and work of USGS scientist Donal R. Mullineaux (1925â??2021), a pioneer in tephra and volcanic hazards research. Don was a Quaternary geologist who while mapping in the Puget Sound lowlands discovered ash beds that led him to Mount St. Helens. His work with Dwight Crandell helped unravel the eruptive history and hazards of Mount St. Helens and other Cascades volcanoes and pioneered the addition of volcanic hazard assessments to USGS hazard products. Don further served as coordinator and spokesman for Geological Survey field operations during the 1980 Mount St. Helens eruption where he is credited with saving lives. Here we welcome submissions covering the broad themes of Donâ??s work on tephraâ??in both volcanology and Quaternary geologyâ??encompassing tephrochronology, eruptive histories, physical volcanology, volcanic hazards and forecasting. We particularly encourage novel and interdisciplinary research that reflects the rapid growth of the field over the last 20 years. Specifically we welcome field studies, analog lab experiments, remote sensing, and microanalytical studies that address: â?¢ tephrostratigraphy and -chronology â?¢ cryptotephra identification and implications â?¢ eruption source parameters and classification â?¢ insights into plume dynamics and ash dispersal â?¢ case studies of recent explosive eruptions from interdisciplinary perspectives â?¢ volcano-specific and regional eruptive histories â?¢ eruption style and emplacement mechanisms (fall, flow, coignimbrite) â?¢ processes that influence the injection and deposition of volcanic ash and gas (e.g., magma-water interaction, vent geometry, ash aggregation, gravitational instabilities, turbulence) â?¢ characteristics of volcanic ash (grain size, morphology, internal textures) â?¢ fragmentation of fine ash â?¢ distinguishing magmatic, phreatomagmatic, and phreatic eruptions We look forward to â??seeing" you there (the meeting will be hybrid with both virtual and live components) Britta Jensen, Heather Wright, Alexa Van Eaton, Thomas Casadevall This session is supported by the following IAVCEI commissions: Tephra Hazard Modelling, Volcanic Hazards and Risk, Tephrochronology 1-1-1-1-1-1-1-1-1-1-1-1-1-1 ============================================================== 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).
