Inland large scale active faults ruptured with great earthquake in historical time and associated crustal movements

历史上曾发生过大地震的内陆大型活动断裂分布较好，并伴有明显的断裂地貌。对这些断裂的形态、详细位置、地质等进行了详细的描述。与之相关的地壳运动也得到了澄清。由于湖泊和冲积低地发育在活动断裂的俯冲边，因此对这些沉积物的岩心样品进行了年代学和其他测年方法的分析，得到了断裂和地壳变形的时间尺度。特别是在别浦湾和碧瓦湖的底部。许多研究人员对地震断层的详细野外观测进行了描述，并将其汇编为带有精确位置图的清单(比例尺1：2,500)。地表主要断层的分布、位移量。通过这些调查总结了累积地形表达等。野岛断裂的发掘研究主要是为了揭示Nashimoto断裂事件的年龄和复发间隔。和田镇。Awai岛：Rokko-Awaji活动断裂系统。并对其进行了野外考察，从地貌上分析了它们的断裂活动性和特征。沉积学和测年方法。沿着低地进行了许多钻探调查。并通过岩性调查和岩心测年，明确了这些活动断裂的活动性和断裂行为。晚第四纪的活动已被阐明与陆源时序的关系。通过照片解译，绘制了六哥山脉南侧冲积平原上活动断裂的分布图。地震反射和钻探勘测。

Inland large scale active faults, which have produced great earthquakes in historical time, well distribute in Kinki area, and accompany clear fault topography. The morphology, detailed location, geology etc.of these faults have been described in detail. and related crustal movements have been clearified. As the lake and alluvial lowlands develop in down-thrown sid of active faults, core samples of these deposits were analyzed by using tephro-chronological and other dating methods for getting the time scale of faulting and crustal deformation. especially in the bottoms of Beppu Bayand Lake Biwa.Detailed field observations for the seismic faults have been described by many researchers and compiled as a list with precise location maps (scale 1 : 2,500). Distribution of major surface faults, amount of displacement. cumulative topographic expression etc.were summarized by these surveys. The excavation study for the Nojima fault has been aimed principally at revealing ages of faulting event and recurrence intervals at Nashimoto. Hokudan Town. Awai Island.The Rokko-Awaji active fault system. which produced the 1995 Hyogoken Nanbu carthquake.has been surveyed in the field.and their fault activity and character were analyzed by the geomorphological. sedimentological and dating methods. Many drilling surveys were carried out along the lowland. And the activity and behaviors of faulting for these active faults were clarified by investigating the lithology and dating for the core samples obtained. The activity during the late Quaternary has been clarified with relation to the terracc choronology. The distribution of active faults bencath the alluvial plainalong the south side of the Rokko Mountains has been mapped by photo-interpretation. seismic reflection.and driling surveys.
