Abstract
Although the fault mechanism of this earthquake has been studied in detail by several researchers based upon plentiful seismic data, there is a fatal defect that the arrival time of the first wave of the tsunami is not explained. The first wave from the north fault, computed with the best tsunami source model, arrives at the shore two minutes later than the measured. If a secondary fault implied in the vertical distribution of aftershocks is assumed effective to generate the first wave, the difference in the arrival time is solved. The computed first wave from the south fault arrives at the shore 10 minutes later than the witnessed. An inverse refraction diagram reveals that the witnessed first wave did not come from the fault area. The generation of the first wave is located between the south fault and the area where aseismic creeping slips occurred before the main shock.
