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

关东南部地形的特征之一是广泛存在的深入阶地的狭窄河谷（低地），这使得该地区的地形非常复杂。此外，阶地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个地区很受欢迎。在本研究中，通过研究这种复杂的地形和地表土壤条件来探讨地震减灾，并提出灾害图和对策。研究了2011年东北地震造成的非均匀液化灾害分布。

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.
