[HDS13-P05] Development of the Tsunami Prediction System using fault plane solution of W-phase inversion
Keywords:tsunami, tsunami scenario database, W phase, tsunami prediction system
In this study, we have developed an algorithm for tsunami prediction capable of analyzing fault plane solution using W phase and simulating tsunami using the fault plane information. We tested the performance of the developed algorithm applying into the case of 1993 Japan tsunami. W phase inversion results were as follows: moment magnitude=7.7, depth=25.5km, strike=170.2°, dip=45.3° and rake=77.8°. As a result of tsunami simulation using the inversion results, the difference between the numerical results (tsunami height and arrival time) and measured data at tide stations was small. Therefore the algorithm for tsunami prediction may be used for tsunami warning as a complement to tsunami scenario database.
