大地震早期検知のための強震動初期波形の理論・データ解析

抄録

This paper presents a method to judge a huge earthquake for an early warning system. The judgement is made by assessing a wave form at an initial stage. In this paper, rate of acceleration is studied, as a possible decision index that is used for the judgement. The following results are shown: 1) the system performance simulation using the physical model of the fault with built-in fault fracture process and, 2) statistical verification of the system accuracy by processing and examining measured data.
