In Antarctica it has not been surveyed and is an important target for explosion experiments. Seismic refraction data from the explosion experiments during the 21st Japanese Antarctic Research Expedition (JARE-21) in 1981 were re-analyzed to detect reflected waves from the lower crust. An explosion in Lutzow-Holm Bay with 3000kg of explosive gave well-recorded seismic waves at 27 stations along a 300km profile on the northern Mizuho Plateau, East Antarctica. A band-pass filtered record section with a normal-moveout velocity of 6.3km/s shows clear phases of large amplitudes in a range of 8-16s of two-way travel time; these phases can be considered as wide-angle reflected waves from the lower crust. The reflection depths correspond to about 18-48km. The depth patterns of reflective layers on the Mizuho Plateau can be related to the Bouguer gravity anomalies and are useful for studying the evolution of the Lutzow-Holm Complex.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008903","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"550.34:551.2","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Disaster Prevention Research Institute, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_value":"研究ノート"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Scientific Note"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"京都大学防災研究所"},{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1995-11-01"}],"displaytype":"detail","filename":"KJ00002478259.pdf","filesize":[{"value":"317.9 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002478259","url":"https://nipr.repo.nii.ac.jp/record/8903/files/KJ00002478259.pdf"},"version_id":"1c0e70e8-1c62-453f-b59f-157b58df94f5"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"人工地震データの再解析によるみずほ高原の下部地殼反射波の検出","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"人工地震データの再解析によるみずほ高原の下部地殼反射波の検出"},{"subitem_title":"Detection of Reflected Waves from the Lower Crust on Mizuho Plateau, East Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["1112"],"pubdate":{"attribute_name":"公開日","attribute_value":"1995-11-01"},"publish_date":"1995-11-01","publish_status":"0","recid":"8903","relation_version_is_last":true,"title":["人工地震データの再解析によるみずほ高原の下部地殼反射波の検出"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:11:51.852781+00:00"}
