Volcanoes produce a wide range of hazards and require an array of strategies in order to adequately protect populations living in their shadow. These monitoring strategies are under continuous development, and observations using methods both old and new reveal novel insights into volcanic processes. The aim of this session is to bring together a multidisciplinary audience to learn about recent innovations in monitoring approaches and to present observations that increase our understanding of volcanic processes. We welcome contributions from all disciplines involved in volcano monitoring, from in-situ methods such as seismic networks, geodetic networks and gas monitoring, as well as ground, air and space-based remote sensing methods. The session will provide an opportunity to discuss volcanic activity from a monitoring perspective on a wide range of volcanoes. We therefore encourage submission of papers that describe novel techniques and observations in a manner that is easily understandable to a broad, multi-disciplinary audience.
