| | Abstract | | In order to reduce the earthquake disaster, it is very important to know the strong ground motion after a big earthquake as soon as possible. In Japan, high-density seismograph networks were installed after the Hanshin-Awaji earthquake. The typical spacing between each seismic station is approximately 20 km. However, there are many cities and towns that have only one seismic station. The Hanshin-Awaji earthquake has shown us the limits of governmental help and importance of the self-help by citizen. The density of seismic stations in Japan is not still enough for civilian self-disaster prevention. So it is important to know strong ground motions with higher density In this article, therefore, a new method to estimate high-resolution seismic intensity maps using only one seismic station data has been developed. The new method is able to estimate seismic intensity of any given point. The new method has been applied to Yokohama City. As the results, high-resolution seismic intensity map has been achieved immediately with good accuracy. |
