Abstract
This paper summarizes liquefaction-induced damage in the Kanto region during the Mw9.0 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.
