[MIS12-P02] Identification method of event deposits caused by natural hazards
Keywords:Natural hazard, Tsunami deposit, uncertainty
We present the identification method of event deposits which can take account of uncertainties of geological information and scale of natural hazards. First, we classified the natural hazards which can make event deposits on land based on their scales and characteristics. Then, we organized sedimentary, geochemical, paleontological survey items by information that we can retrieve from event deposits. We evaluated uncertainties of geological information by assuming the probability distributions for each information. The probabilities of event deposits being made by each natural hazard were presented with the uncertainties. In the presentation, we will show some examples of this identification method and discuss its effectiveness compared with the existing identification methods.
