 Using the Enks method, I also verified whether it can be predicted with sufficient accuracy even in the S-net observation network. As a result, it is clear that the tsunami real-time prediction can be performed with almost the same precision...

 By using the ensemble Kalman smoother (Enks), we examined whether it is possible to predict tsunami immediately with a higher degree of accuracy than the ensemble Kalman filter (Enkf). In order to use a fixed lag smoother in Enks, we firstly...

 Effect of ensemble member was examined by twin experiment on accuracy of real-time tsunami pre-diction by ensemble Kalman filter using the observation data of tsunami gauges. As a result, it is clear that there is an unacceptable error by ensembl...

 In order to solve the problems of the inversion methods commonly used in the field of real-time tsunami prediction using the observation data of tsunami gauges, the ensemble Kalman filter method which is one of the data assimilation methods is ap...

Research Grants & Projects

 
Study on Tsunami numerical waring system
The Other Research Programs
Project Year: 1999   
It is important to transmit the accurate information of the tidal wave that attack is predicted to the inhabitant rapidly to reduce human damage due to the earthquake tidal wave. At present, because it is based on the seismic information, as for t...
Estimation of Tsunami initial waveform using inversion method
The Other Research Programs
Project Year: 1999   
The value which could get it by the actual observation isn't used, but the lead ground displacement estimated from the earthquake fault model is supposed displacement on the surface of the sea as it is, and the source of wave used as the initial c...
