In this study, damage to Hiroshima-Kure-Matsuyama region due to the Geiyo earthquake of June 2, 1906 was re-examined from multi-viewpoints of various research fields in a comprehensive manner, aiming at promotion of regional disaster prevention through the inter-disciplinary collaboration.Firstly, in order to collect materials on the Geiyo earthquake disaster, literature survey and questionnaire investigation were conducted. Some of collected items, including newspaper articles, reconnaissance reports, archives of various organizations, etc. have been compiled as appendices of the final report for further study.Sonar investigation was carried out around the epicentral region in Aki-nada sea area to identify sea-bed fault causing the Geiyo earthquake. No sea-bed fault could be found, which proved that tsunami was not induced by the earthquake. Fault-rupture simulation using FEM method and synthesis of small fault-rupture process was also performed. Seismic intensity at Hiroshima-Kure re … More gion was estimated as V to VI on the JMA scale.Much effort was devoted to the investigation of ground condition of the disaster-stricken area. Predominant period of ground in Hiroshima and Kure was determined by conducting both measure of microtremors and theoretical analysis employing multi-reflection theory. Liquefaction possibility in Matsuyama was analyzed and it was concluded that no liquefaction occurred, which coincided with the fact that no evidence of liquefaction was found. Furthermore, "vibro-corer" was invented for future use as an easy-to-operate device to sample soil piece of alluvium layr.Fundamental studies on earthquake damage prediction were carried out in terms of seismic hazard analysis and damage assessment of buildings. In order to identify most-concerned seismic region, seismic hazard of Hiroshima city was analyzed, which showed the seismic activity in Aki-and Iyo-nada area had substantial contribution to the seismic hazard in Hiroshima. Dynamic response analysis of wooden structures and damage rate estimation of reinforced concrete structure were performed with emphasis on the effect of soil amplification. Less

本研究从多个角度对1906年6月2日庆应地震对广岛-高丽-松山地区造成的破坏进行了重新审视，旨在通过学科间的协作促进区域防灾工作。首先，通过文献调研和问卷调查，收集了庆应地震灾害的资料。收集到的部分资料，包括报纸文章、勘察报告、各机构的档案等，已编入最终报告的附录中，以供进一步研究。在秋奈田海域震中附近进行了声纳调查，以确定庆应地震的海床断层。没有发现海底断层，这证明海啸不是由地震引起的。利用有限元方法进行了断层破裂模拟，并对小断层破裂过程进行了综合。广岛-Kure Re…地震烈度在JMA等级上，更多的区域被估计为V到VI。大部分工作致力于灾区地面条件的调查。利用多次反射理论对广岛和库雷的地震动进行了测量和理论分析，确定了广岛和库雷的地面优势周期。对松山的液化可能性进行了分析，认为松山没有发生液化，这与没有发现液化的证据是一致的。此外，还发明了“振动取样器”，作为一种易于操作的设备，用于采集冲积层土块的样本。从地震危险性分析和建筑物破坏评估的角度，开展了震害预测的基础性研究。为了识别最受关注的地震区，对广岛市的地震危险性进行了分析，结果表明，秋田区和池田区的地震活动对广岛市的地震危险性有很大的贡献。对木结构进行了动力响应分析，并对钢筋混凝土结构进行了损伤率估算，重点分析了土体放大效应。较少
