At present, the areas where liquefactions were identified extend from Aomori Prefecture in the north to Kanagawa Prefecture in the south within approximately 650-km long zone. This earthquake was characterized by the long duration of ground motion with several successive events of the source area. In this paper, firstly we examined the liquefaction occurrence ratio in terms of measured seismic intensities by geomorphologic classification units based on a dataset of strong ground motion data and observation records of liquefaction sites during the 2011 off the Pacific coast of Tohoku Earthquake to show the liquefaction potentials differing between the Tohoku and the Kanto regions. Next, in order to investigate the effect of the ground motion duration, we calculated the real-time seismic intensity and its accumulated index (\u003ci\u003eΔIs\u003c/i\u003e) as explanatory parameters of ground motion intensity. As a result, although it was found that there was still regionality in the Tohoku and the Kanto regions, it clarified that the large \u003ci\u003eΔIs\u003c/i\u003e caused to increase the liquefaction occurrence ratio.\u003c/p\u003e", "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.18.2_82"}}]}, "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": "先名重樹", "creatorNameLang": "ja"}, {"creatorName": "先名重樹", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "松岡昌志", "creatorNameLang": "ja"}, {"creatorName": "松岡昌志", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "若松加寿江", "creatorNameLang": "ja"}, {"creatorName": "若松加寿江", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "翠川三郎", "creatorNameLang": "ja"}, {"creatorName": "翠川三郎", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_title": "液状化発生率におよぼす強震動の継続時間と地域性の影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "液状化発生率におよぼす強震動の継続時間と地域性の影響", "subitem_title_language": "ja"}, {"subitem_title": "Liquefaction Occurrence Ratio Estimation Considering Strong Ground Motion Duration and Regional Characteristics", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5963", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5963", "relation": {}, "relation_version_is_last": true, "title": ["液状化発生率におよぼす強震動の継続時間と地域性の影響"], "weko_shared_id": -1}
