The method is based on an empirical transfer function for the seismic wave propagation path between a location close to the hypocenter of anticipated earthquakes and the location where ground motions are to be predicted. The transfer function is first identified in the form of a state-space equation using previously observed earthquake records and it is then used for the real-time prediction of earthquake ground motions as the earthquake occurs. Upon the occurrence of an earthquake near the considered hypocenter, the seismic waves reach the location near the hypocenter. The observed time-history becomes the input to the state-space equation and the ground motions of the other site are calculated in real time before their arrival. To validate the proposed method with respect to the relatively long-period components of earthquakes, theoretically calculated seismic waves on the surface of layered half space and earthquake records observed in Japan were used. An economical method of transferring the observed earthquake records using broadband Internet is also studied experimentally and the time delay is evaluated.
