Abstract submission: https://meetingorganizer.copernicus.org/EGU2019/session/31889 We are looking forward to see you in Vienna! Marco Fazio, Philip Benson, Peter Rowley Session description: Volcanic unrest is often preceded or accompanied by volcano-related seismic signals. These occur as individual event or form swarms, which eventually merge into continuous volcanic tremor. Although volcano-seismic signals have been recorded for almost 50 years, a universally agreed classification of such signals is still missing. This is due to the fact the source mechanism behind them is still under debate, particularly for the Long Period (LP) seismicity where different source models have been proposed based on both laboratory and field studies. Laboratory studies, in fact, have successfully simulated shallow volcanic conditions and generated Acoustic Emissions (AEs) events, which are the laboratory analogue of field events. Problems arise also from the monitoring technique, since some of these signals lack of broadband frequency content or they can be recorded only in the vicinity of the active craters. Monitoring and analyzing volcano-seismic signals is crucial to understand the volcanic processes, as well as to characterize the volcanic fluids involved. In addition, it has been proved that this seismic activity can be used to forecast volcanic eruption, even though mostly in hindsight. Therefore, in this session we aim to shed light upon this topic by bringing together researchers working on volcano-seismic signals, from the laboratory to the field scale. We are interested in the analysis of such events both in time- and in frequency-domain, their reliability in eruption forecasting models and their seismogenic processes. ============================================================== 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).
