Development of the Global Tsunami Prediction System using the Finite Fault Model and the Cyclic Boundary Condition

摘要

A global tsunami prediction system was suggested for a distant tsunami using a finite fault model and a cyclic boundary condition.The possibility of the suggested system as a distant tsunami response system was checked by applying it into the case of 2014 Chile tsunami.A comparison between the numerical results(tsunami height and arrival time) with different conditions (boundary condition,governing equation,grid size and fault model) and measured data (DART buoy,tide station) showed the importance of the finite fault model and the cyclic boundary condition.
