Bridging the gap between the geoscience and loss assessment communities
To supplement this important step towards better quantification of uncertainties in seismic loss estimates, the JRI also aims to come up with a new approach to enable the correct propagation of these uncertainties in all steps of the computations and consider them in the outcome results. Moreover, visualisation tools will be developed by the JRI teams to help both the geoscience community to identify the relevant data that should be collected to reduce epistemic uncertainties and the risk community by identifying where the uncertainties in hazard models are coming from and thus help in the decision-making process.
To avoid the potentially devastating consequences of badly informed decision-making, creating a dialog between the geoscience and risk communities is paramount. In joining forces, the ENS – IRSN team and the AXA team aim to bridge the gap and provide each other with mutual insight on how to improve estimations and keep uncertainties in the loop. In this sense, the AXA Joint Research Initiative has the potential to significantly contribute to the improvement of seismic hazard mitigation.
