Abstract
On the 11th of March 2011, the Off the Pacific Coast of Tohoku Earthquake （MW=9） has hit Japan and caused severe liquefaction damage over entire stretch of reclaimed lands along the coast of Tokyo Bay. The aim of this study is to investigate the relationship between liquefaction potential and liquefaction-induced road subsidence occurred in Urayasu city in the 2011 the Off the Pacific Coast of Tohoku Earthquake, and then to develop a new hazard map reflecting this relationship, which provides expected liquefaction-induced road subsidence in the scenario earthquake. This map would be useful not only for damage estimates by the liquefaction, but also for determination of the best routes for emergency vehicles for local governments.
