T85. Volcanic deposits as a tool to quantify volcanic hazards towards disaster risk reduction

Volcanic hazards like pyroclastic density currents, volcanic plumes, tephra fallout, lahars, dome collapse, debris avalanches, etc. are natural phenomena that are challenging to fully understand, reproduce and forecast in models. Thankfully, all these processes leave a footprint in the geological record that is often a precious (sometimes, the only) source of data which can be used to characterize the process and eventually quantify the hazard. This is particularly crucial for volcanoes that do not erupt frequently or have not erupted in historical times, i.e., volcanoes for which observational data are missing. The ways to quantitatively analyse this geological record and use the field data to model the process generating the deposits, though, are still an open research question for many of the volcanic hazards.
In this session we welcome contributions that deal with the characterization of volcanic processes via the analysis of volcanic deposits. Research bridging the gap between the field evidence and the hazard quantification are particularly encouraged.
