The linear long-wave theory is used in the first stage to find the tsunami initial profile. The perfect reflection is assumed at the land boundary. On comparing the computed with the measured overall runup distribution, the best fault model is found among 24 models. It consists of three sub-faults dipping westward. It satisfies the measured land subsidence and overall distribution of runup heights in Okushiri Island. Then, the shallow-water theory with bottom friction is used to simulate runup. The runup condition is used as the land boundary condition. The arrival time and runup heights agree well with the measured.
