Volcanoes are, understandably, considered one of the most important natural hazards. Recent volcanic eruptions have led to significant human loss and considerable economic damage. Accurate hazard estimation is fundamental in increasing preparedness and mitigating potential risks from volcanoes.Today, multiple disciplines of geosciences have been involved in this topic and interdisciplinary actions demonstrate significant promise.Traditionally, volcanoes have been explored through seismic signals, by studying sequences of earthquakes related to volcanic activity. However, advanced seismology has developed more sophisticated approaches that offer greater potential, whether by analyzing ambient noise recordings or documenting stress changes through shear-wave splitting and classifying volcanic tremors.Temporal variations of surface deformation have been studied with the aid of GNSS networks and data-analysis techniques, as well as gravity measurements.Moreover, gas emissions have been extensively used in investigating volcanic processes. Finally, the emerging field of geological disaster management can contribute significantly in improving the response of authorities and reduce potential secondary damages. The combination of monitoring and management plans is critical in successfully and efficiently reducing risk.In this session, we invite contributors dedicated to monitoring volcanoes from fields of geosciences, including researchers involved in the analysis of seismic, GNSS, gravity and geochemical data, to submit their work on advanced,innovative approaches of applying current and past knowledge in estimating and modelling volcanic hazard, as well as experts on the risk management field to share their work on improving response for potential disasters.
