The conclusions can be summarized as follows :1) It is shown that the earthquake activities of western Japan have became active after western Tottori Earthquake occurred on the afternoon of Octobcr 6, 2000. 2) Estimates of the Q value for two profiles from the Geiyo earthquake, show that the attenuation is lower for the path that pases through the subducting Philippine Sea slab. 3) 3D gravity inversion of basement relief in the Hiroshima plain, western Japan, was performed using precise data measured in and around the plain. It is important to note that an NNE-SSW oriented trough-like depression is revealed to exist along the western edge of the plain, where damage to houses was remarkably severe. 4) On the basis of the questionnaire survey on seismic intensity in whole Chugoku and Shikoku areas mainly affected by this earthquake, the fact that higher seismic intensities than the instrumental ones were estimated in many areas by the questionnaire survey. 5) Collapse of stone retaining … More wall and slope surface collapse in cases of Kure and Kouchi districts respectively were strongly related to topographical and geological features and characteristics of observed earthquake motions. 6) The roof-tile damage of wooden houses in the residential area of hill-side looks to coincide with ground condition of cut or fill. Difference in dynamic characteristics due to micro-tremor measurement has been found between fill and cut. Moreover, the second earthquake resistance diagnosis method must be taken into account of brittle columns or shear-failed columns, in order to lead the results of earthquake resistance diagnosis of two reinforced concrete school buildings and their damage by the earthquake. 7) Although the physical damage to utility lifelines was not catastrophic as a whole, there occurred functional damage spread, which is typical of urban earthquake disaster. 8) Social responses shown by mainly people, local govemments, and private enterprises in Hiroshima prefecture after the earthquake are investigated.

结果表明：1）2000年12月6日下午鸟取县西部地震发生后，西部地震活动趋于活跃。2)估计的Q值的两个配置文件从Geiyo地震，表明衰减是较低的路径，通过俯冲菲律宾海板块传递。3)利用日本西部广岛平原及其周边地区的精密重力测量数据，对该平原的基底起伏进行了三维重力反演。值得注意的是，在平原的西部边缘沿着有一个北北东-南西西向的槽状低压，那里的房屋受损非常严重。4)根据对这次地震主要影响的整个中国和四国地区的地震烈度进行的问卷调查，通过问卷调查，估计出许多地区的地震烈度高于仪器测定的烈度。5)挡石坍塌 ...更多信息 吴县和口知县的墙体和坡面倒塌与地形地质特征和观测到的地震运动特征密切相关。6)山坡住宅区木结构房屋屋面瓦损与填土或挖方地基条件相吻合。由于脉动测量的动力特性的差异已被发现之间的填充和切割。另外，第二种抗震诊断方法必须考虑脆性柱或剪切破坏柱，以指导两栋钢筋混凝土教学楼的抗震诊断结果及其在地震中的破坏情况。7)虽然城市生命线的物理破坏总体上不具有灾难性，但却发生了典型的城市地震灾害的功能性破坏蔓延。8)本文调查了广岛县地震后主要是民众、地方政府和民间企业的社会反应。少
