A Study on Fault Modelling for the Japan Sea Area Based on the Off Shore Faults Research Project
Abstract eng: To investigate fault modeling in the Off shore Fault Evaluation Group, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) has collected marine seismic industry, velocity structure, and observational well data to create a three-dimensional structure database under high quality control. The marine seismic industry data from the Japan Sea have been re-processed since 2014. By combining these and past data, a new analysis of the fault data was made and a unified fault interpretation was developed. Based on the results, continuous fault configurations were confirmed against structural geology and topography measurements. By interpreting the finished model, the National Research Institute for Earth Science and Disaster Resilience (NIED) is presently creating a list of main faults from a distributive fault in the Japan Sea. The validity of the fault model was examined by constructing a model for the 1940 Shakotan-Oki earthquake.
