| Research Abstract |
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.
