リアルタイム地震観測ネットワークを用いた地震動予測に関する研究

一前線の波形情報を用いた最大値指標の予測一

The Japan Meteorological Agency (JMA) provides Earthquake Early Warnings (EEW) for advanced users from August 1, 2006. Advanced EEW users can forecaste seismic ground motion (example: Seismic lntensity, Peak Ground Acceleration) from information of the earthquake in EEW. But there are limits to the accuracy and the earliness of the forecasting. This paper describes regression equation to decrease the error and to increase rapidity of the forecast of ground motion parameters from Real Time Earthquake lnformation based on wave form data at the front site．
