Crustal movements larger than 5 m were observed on the land after the earthquake. In this study, a method to grasp the surface movement from pre- and post-event TerraSAR-X intensity images was proposed. Since the shifts of non-changed buildings between the two SAR images can be seen as the crustal movements, firstly the buildings in the pre- and post-event images were extracted by a segmentation approach. Then non-changed buildings were detected by matching the buildings in the pre- and post-event images at similar locations. Finally, the shifts were calculated by area-based matching. The method was tested on the TerraSAR-X images of Tohoku region and central Tokyo, and the accuracy was verified by the observed data from GPS ground stations.", "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.12.4_3"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "リュウ ウェン", "creatorNameLang": "ja"}, {"creatorName": "LIU Wen", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山崎 文雄", "creatorNameLang": "ja"}, {"creatorName": "YAMAZAKI Fumio", "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前後のTerraSAR-X強度画像を用いた 地殻変動の検出", "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前後のTerraSAR-X強度画像を用いた 地殻変動の検出", "subitem_title_language": "ja"}, {"subitem_title": "Estimation of crustal movement due to the 2011 Tohoku, Japan Earthquake from TerraSAR-X intensity images", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5942", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5942", "relation": {}, "relation_version_is_last": true, "title": ["2011年東北地方太平洋沖地震前後のTerraSAR-X強度画像を用いた 地殻変動の検出"], "weko_shared_id": -1}
