4-4-4-4-4-4-4-4-4-4-4-4-4 From: "Crozier, Joshua A" <jcrozier@xxxxxxxx> Hello all, We invite contributions to our session "V020 - Volcano Seismology and Acoustics: Recent Advances in Understanding Volcanic Processes" at the AGU 2022 Fall Meeting, taking place in Chicago and online from December 12-16. Hazardous phenomena at volcanoes include ash plumes, gas emissions, explosions, pyroclastic density currents, lava flows, lahars, and mass wasting. All of these processes produce seismic and acoustic signals that can provide key real-time information for assessing hazardous surface and atmospheric activity. We can also gain insights into the structure and activity state of volcanoes by identifying and tracking the movement of subsurface magma and hydrothermal fluids using seismicity and seismic imaging techniques. Recent advances in seismo-acoustic instrumentation, deployment techniques, and data analysis have promoted more precise characterization and quantification of the physical mechanisms leading to and accompanying volcanic phenomena. Thus, volcano seismology and acoustics remains a rapidly developing area of research. We welcome submissions that present new seismic, infrasound, and hydroacoustic observations, interpretations, models, instrumentation, or techniques that improve our understanding of volcanic processes and assist future monitoring efforts. This year our invited speakers are Ettore Biondi from Caltech and Julia Gestrich from the University of Alaska Fairbanks. Best, Helen Janiszewski Jackie Caplan-Auerbach Josh Crozier Oliver Lamb 4-4-4-4-4-4-4-4-4-4-4-4-4 ------------------------------
