Conventional volcanological studies are still the most important tools for understanding the volcano behaviour. At the same time, the extensive use of geophysical networks (seismometers, infrasonic arrays, gravity meters), interpretation of deformation data (GPS, InSAR), and the measurement of volcanic gas emissions allowed to significantly improve the chance to forecast the onset of volcanic crises or the shift in intense eruptive activity. This session aims at bringing together a multidisciplinary audience to discuss about the integration of volcanological observations with monitoring data, with special attention to the problems involved in forecasting both eruptive events and the shift in intense volcanic activity. We welcome contribution related to (1) the integration of different monitoring records with conventional volcanological data (field observations, geochemical and petrological studies, textural analysis, etc) and their significance in terms of eruption forecasting; (2) reports of significant case histories, documenting the relationships between the measured parameters, modelling frameworks and the evolving volcanic processes.The session will provide an opportunity to discuss volcanic activity from a comprehensive perspective on a wide range of volcanoes. We therefore encourage submission of abstracts that are easily understandable to a broad, multi-disciplinary audience.
