Knowledge Notes, Cluster 5: Hazard and Risk Information and Decision Making
In Miyagi, the government predicted a high probability of an earthquake occurring but underestimated its size and the ensuing tsunami risk. The official hazard map depicted risk areas that were smaller than the area actually affected by the GEJE. Given the uncertainties associated with hazard prediction and risk assessment, earthquake and tsunami risks should be assessed based on multiple scenarios, taking into account every conceivable eventuality and utilizing all the tools science has to offer. They should also be informed by historical records going back as far as possible, combined with a thorough analysis of the literature in the field, topographical and geological studies, and other scientific findings.
