Microlevel earthquake disaster mitigation focused on the slopes between two landforms typical of Tokyo metropolitan area

关东南部地貌的特征之一是普遍存在深入梯田的狭窄河谷(低地)，这使得该地区的地貌非常复杂。此外，梯田和低地之间的大部分边界都形成了陡峭的斜坡，这意味着不规则的地面在这一地区很常见。在这项研究中，通过研究这一复杂的地貌和表层土壤条件来讨论地震减灾问题，以提出危险地图和对策。还研究了2011年东北地震引起的液化损伤分布不均匀问题。

One of the characteristic features of the landform in Southern Kanto is the existence of a widespread narrow river valleys (lowland) that penetrate deep into terrace, which makes the landform of this area very complex. In addition, steep slopes are formed along most of the boundaries between terrace and lowland, meaning that irregular ground is quite popular in this area. In this study, earthquake disaster mitigation is discussed by looking into this complex landform and surface soil conditions to come up with hazard maps and counter measures. Also studied is non-uniform liquefaction damage distribution due to 2011 Tohoku earthquake.
