项目摘要
Holocene surface faultings are newly recognized in the eastern boundary faults of the Shonai Plain, the western boundary faults of the Yamagata Basin and the eastern boundary faults of the Kamishiro Basin along the Northem part of Itoigawa-Shizuoka Tectonic Line, based on the interpretation of large-scale air photographs and the field survey. Holocene and late Pleistocene deformation is demonstrated along theses faults, and the degree of faults activity, based on vertical displacement, is class A to B (slip rate ; 0.1-1.5m/ka).Holocen flexural scarps of one to two meters or less in relative height is characteristic deformed feature along these faults, implying that this is resulted from low angle reverse faulting.Holocene flexural scarps are situated one hundred meters to one kilometer off from the piedmont line, which indicates that Holocene reverse faulting migrates to the basin. The fold systems well develop in the study areas, which shows that the folding is related to the late Quaternary faulting in the unconsolidated basin deposits.In conclusion, (1) active reverse faults are associated with Holocene flexural scaps which have very gentle slope, (2) the interpretation of large-scale air photographs is helpful to the recognition of active reverse faults which have high seismic risk.
全新世表面断层在肖奈平原的东部边界断层,Yamagata盆地的西部边界断层以及Kamishiro盆地的东部边界断层沿Itoigawa-Shizuoka Tectonic线的北部部分的东部边界断层,基于对大型空气照片的解释。沿这些故障证明了全新世和更新世晚期的变形,并且基于垂直位移的故障活动程度是A级至B(滑动速率; 0.1-1.5m/ka).HOLOCEN的弯曲疤痕的弯曲疤痕是一米或更少的一米或更少的相对高度的相对高度的特征是沿这些故障,这是符合这些故障的特征,使得符合这些故障,这是在这些缺陷中,与这些故障相关,这是在这些缺陷中所带来的,这是符合这些缺陷的范围,这是符合这些缺陷的范围。距离皮埃蒙特线(Piedmont Line)一百米到一公里,这表明全新世反断层迁移到盆地。折叠系统在研究区域中良好发展,这表明折叠与未固结的盆地沉积物中的季节性断层有关。结论,(1)主动反向断层与全新世弯曲的斜坡相关,这些弯曲斜坡具有非常柔和的斜坡,(2)对大型空气照片的解释有助于对现有反向反向逆转的识别,这有助于较高的反向反向逆转状况。
