Abstract

This paper summarizes liquefaction-induced damage in the Kanto region during the M_w9.0 Off the Pacific Coast of Tohoku earthquake of March 11, 2011, focusing on land and geomorphologic conditions of affected areas. Based on this study the following conclusions were reached: liquefaction was observed at a total of 130 cities, towns and villages in all seven prefectures in Kanto regions, whose numbers of 7.5-arc-second grid cells are 7,987; most of the liquefaction occurred in the areas where the instrumental seismic intensity exceeded 5.0; liquefaction took placed in the areas along the big rivers and filled land along the Tokyo Bay and developed land in the small valleys among the terrace; and liquefaction occurrence rate for each geomorphologic unit within the areas of the instrumental seismic intensity exceeded 5.0 is the highest for filled land (25.7%) among 23 geomorphologic unit.
