3-3-3-3-3-3-3-3-3-3-3-3-3 Dear Colleagues and Friends, we invite you to submit an abstract to the session we are organizing within the next AGU Fall Meeting, that this year will be mostly virtual from 7-11 December. *Session V028 | Volcanic hazards: from monitoring to impacts*Volcanic eruptions are characterized by multiple hazards that must each be recognized and assessed in order to mitigate their impacts. Quantifying volcanic hazards by combining satellite data and numerical modelling finds immediate application to the real-time monitoring of eruptive events. By monitoring, we mean here both following the manifestations of the eruption once it has started, as well as forecasting the areas potentially threatened by hazardous phenomena producing different scenarios as eruptive conditions change. Real-time monitoring and modelling of hazardous phenomena are powerful tools also to assess and mitigate the associated impacts. Today a satellite-driven modelling strategy able to give during an eruption the current state of the activity, the probable evolution of hazardous phenomena and the potential impact scenario is realistic. We welcome contributions showing effective ways to integrate remote sensing observations and numerical models for a reliable assessment of volcanic hazards and their impacts, particularly during on-going eruptions. The link for the abstract submission is https://agu.confex.com/agu/fm20/prelim.cgi/Session/105138. The deadline is *Wednesday, 29 July.* 3-3-3-3-3-3-3-3-3-3-3-3-3 ------------------------------
