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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"5942","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_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T09:33:09.208576+00:00"}
