Outline of Final Research Achievements

Reliable strong ground motion prediction is a quite important issue for evaluation of seismic hazard from future large earthquakes occurring in the plate sub-ducting area. We have constructed a prototype of earthquake source model for broad-band strong ground motion simulation based on the knowledge of characteristics of earthquake sources of past occurred earthquakes. We have also investigated period-dependent source mode of the 2011 Tohoku earthquake and the 2011 Off Ibaragi earthquake. Long-period ground motion characteristics in the Osaka basin during the 2011 Tohoku earthquake have been obtained and ground motion modeling using a characterized source model based on Asano and Iwata (2012) and a Japan Integrated Velocity Structure model (Koketsu et al., 2008) have been conducted for explaining those ground motion characteristics.

Academic Significance and Societal Importance of the Research Achievements

プレート境界で発生する巨大地震による強震動の予測は,地震ハザードを適切に評価するために必要不可欠なため,その予測手法は,その時点までに得られた,発生した地震の知見,に基づいて更新されて行く必要がある.本研究で得られた広帯域強震動予測を目指した震源断層モデル構築手法は,そういった知見に基づいて構築され,実データに基づいたモデルであると言える.このモデル構築手法が適用されて地震ハザード予測の高度化に資するとともに,最新の知見を踏まえて更新されていくことが重要である.
