'''Description'''

A framework for probabilistic hazard assessment of lahars within a multi-hazard environment developed by [https://doi.org/10.3389/feart.2017.00073 Tierz et al. (2017)] that uses a Bayesian Belief Network model (''Multihaz'') for lahar triggering, coupled with a dynamic physical model for lahar propagation (''LaharFlow''). ''Multihaz'' is used to estimate the probability of lahars of different volumes occurring given information about regional rainfall, scientific knowledge on lahar triggering mechanisms and probabilistic assessment of available pyroclastic material from tephra fallout and pyroclastic density currents. ''LaharFlow'' propagates the uncertainty and probabilities modeled by ''Multihaz'' into hazard footprints of lahars. 

The framework is applied to Somma-Vesuvius (Italy).
