项目摘要

In this project, we have conducted various researches on large active faults in Japan. In northwestern Hokkaido, crustal shortening rate was estimated for the Teshio fault zone (Echigo et al.,2006). In Tohoku district, slip rates and earthquake history were constructed for the active faults in Nagai and Aizu basins (Nakamura et al.,2006). After the 2004 Mid-Niigata Prefecture earthquake, Kim and Okada (2005) conducted geomorphic survey of the epicentral area. High-density gravity survey was also conducted by Toda et al.(2005) in conjunction with seismic reflection survey by ERI, University of Tokyo. In Kinki district, Ishiyama and Mueller (2005) examined relationship between surface deformation and subsurface fault structure for the Yoro-Kuwana fault zone. Komatsubara (2006) constructed slip rate distribution of the fault zone on the western margin of Lake Biwa : the maximum slip rate of 1.2-2.3 mm/yr is identified along the central portion of the fault zone. Toda (2006) compiled data on seismic reflection profiles and gravity surveys in Kinki district and discussed tectonic evolution of the study area. Nishiyama et al.(2005) identified faults that ruptured during the 1662 Kanbun earthquake. Okada (2006) pointed out that the last faulting event on the Median Tectonic Line in Shikoku triggered rupture of the Arima-Takatsuki fault zone. In central Kyushu, slip rates and paleoseismic activities of normal faults in Beppu and Unzen grabens were examined by field mapping and trenching studies (Takemura et al.,2005;Takemura,2006;Matsuoka et al.,2005). In order to better predict strong ground motion associated with large earthquakes on active faults, fault parameters and their statistical treatment were discussed by Kumamoto (2005,2006) and Kumamoto and Hamada (2005).
在这个项目中,我们对日本的大型活动断层进行了各种研究。在北海道西北部,估计了Teshio断裂带的地壳缩短速率(Echigo et al.,2006)。在东北地区,建立了永井盆地和会津盆地活动断层的滑动速率和地震历史(Nakamura et al.,2006)。2004年新潟县中部地震后,Kim和Okada(2005)对震中地区进行了地貌调查。Toda等人(2005)也进行了高密度重力测量,并与东京大学ERI的地震反射测量相结合。在Kinki地区,Ishiyama和Mueller(2005)研究了Yoro-Kuwana断裂带的地表变形和地下断层结构之间的关系。Komatsubara(2006)构造了琵瓦湖西缘断裂带的滑动速率分布:沿断裂带中部确定了最大滑动速率为1.2-2.3 mm/yr。Toda(2006)整理了近基地区的地震反射剖面和重力测量资料,讨论了研究区的构造演化。Nishiyama等人(2005)发现了在1662年Kanbun地震中破裂的断层。Okada(2006)指出四国中构造线的最后一次断裂事件引发了Arima-Takatsuki断裂带的破裂。在九州中部,通过野外测绘和沟槽研究,研究了别府和云禅地堑正断层的滑动率和古地震活动(Takemura等,2005;Takemura等,2006;Matsuoka等,2005)。为了更好地预测活动断层与大地震相关的强地震动,Kumamoto(2005,2006)和Kumamoto and Hamada(2005)对断层参数及其统计处理进行了讨论。
