Connecting seismic and acoustic signals recorded around volcanoes to subsurface and subaerial processes is crucial for improving monitoring, as well as for eruption forecasting and characterization. In particular, combining seismic and acoustic data with theoretical, numerical, conceptual, and probabilistic models has become essential to identify repetitive patterns, the opening of fractures and cracks beneath the surface, the transfer of magma through the crust and shallow subsurface, the accumulation of gases beneath volcanic craters, eruptive activity of varied styles, surficial mass movements, or the sensitivity of volcanoes to external forces (e.g., far-field earthquakes, tidal stresses). In this session,we invite contributions focused on the study of seismic and/or acoustic signals around volcanoes and the robust interpretation of these signals. We encourage presentations that combine seismic and/or acoustic data with other observables, data science, and cutting-edge modeling techniques aiming to shed light on new monitoring strategies to better forecast the onset, duration, intensity, and end of volcanic events.
