4-4-4-4-4-4-4-4-4-4-4-4-4 From: Hugo Ortiz <hdortiz@xxxxxxxx> Dear colleagues: Please consider submitting contributions in volcano seismology and acoustics to session V025 at the upcoming AGU 2023 fall meeting. *Session title:* Seismic and Acoustic Signals of Volcanic Unrest and Eruption: from Source Characterization to Monitoring Applications https://urldefense.com/v3/__https://agu.confex.com/agu/fm23/prelim.cgi/Session/185223__;!!IKRxdwAv5BmarQ!d0N3K0Fl2pTIVOcdF1Ip2zHLz-vJ1-hl5aZZ8LrxyGT5m-xyRnUIJ0YXO5-U0G3v7PLOwjH9w_EgYGCx$ <https://urldefense.com/v3/__https://agu.confex.com/agu/fm23/prelim.cgi/Session/185223__;!!IKRxdwAv5BmarQ!d4Ox0xNBjJE09yT5U8fu7e-h9wGQupQOdigj-3B4_10HLgyID6Dmds4HoNgLMktIDbQkYwDGFM8FbWxD$> *Session description:* Advances in seismic and acoustic (seismo-acoustic) research have now substantially improved our knowledge of volcanic systems at different stages of unrest, providing critical information for eruption monitoring. However, challenges remain throughout the entire workflow from signal detection, analysis, and inversion to interpretation of seismo-acoustic and volcanic source processes. New methods and conceptual models derived from field observations, laboratory experiments, and numerical modeling are improving the understanding of phenomena involving coupled elastodynamic and multiphase volcanic fluid processes. This session discusses recent advances in volcano seismo-acoustics and particularly welcomes studies incorporating multiparametric observations such as deformation, gas emission, and thermal and visual imagery. We encourage submissions examining advances in instrumentation, data acquisition, machine learning, and waveform inversion. We highlight research that combines seismo-acoustic observations with numerical and/or laboratory experiments. This session aims to assemble a worldwide perspective on volcanic seismo-acoustic processes from fundamental research to monitoring implementation. *Invited speakers:* Laura Spina - Istituto Nazionale di Geofisica e Vulcanologia Ricardo Garza-Girón - Colorado State University *Conveners:* Hugo Ortiz - University of California, Santa Barbara Darren Tan - University of Alaska Fairbanks Julia Gestrich - Ludwig-Maximilians Universität München Robin Matoza - University of California, Santa Barbara 4-4-4-4-4-4-4-4-4-4-4-4-4 ------------------------------
