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.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人 日本地震工学会","subitem_publisher_language":"ja"},{"subitem_publisher":"JAPAN ASSOCIATION FOR EARTHQUAKE ENGINEERING","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.5610/jaee.15.2_25"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1884-6246","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"若松加寿江","creatorNameLang":"ja"},{"creatorName":"若松加寿江","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"先名重樹","creatorNameLang":"ja"},{"creatorName":"先名重樹","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"2011年東北地方太平洋沖地震による関東地方の液状化発生と土地条件","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2011年東北地方太平洋沖地震による関東地方の液状化発生と土地条件","subitem_title_language":"ja"},{"subitem_title":"Liquefaction and their Site Conditions in Kanto Region during the 2011 Off the Pacific Coast of Tohoku Earthquake","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"5948","relation_version_is_last":true,"title":["2011年東北地方太平洋沖地震による関東地方の液状化発生と土地条件"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T09:33:17.495555+00:00"}
