| Outline of Final Research Achievements |
We proposed method to predict S-wave at target site from observed P-wave at reference site due to upgrading the Earthquake Early Warning and inspected applicability of this method. Procedure of this method shown as follow, 1: transfer function is estimated from ratio of P-wave and S-wave calculated based on ray theory, 2: S-wave is calculated by the convolution of observed P-wave and the transfer function. The IIR filter which calculates the transfer function in time domain was estimated because predicted S-wave has to be calculated in real time. As a result, applicability of this method was confirmed by analysis using M5 earthquake. However, we could not confirm applicability to the Nankai trough earthquake because we cannot get simulation waves include P-wave.
