Judging from the diagram of the attenuation of tsunami height with distance, the tsunami magnitude (Imamura-Iida scale: m) was determined to be m=0.5. This is relatively high for an earthquake having a magnitude of M=7.1. The source area which was inferred from an inverse refraction diagram is located on the north end of the main tsunami source. The length of the tsunami source is 60km in the E-W direction and the source area 1.9×10^3km2. The sea-bottom of the source area seems to be uplifted, because the initial motion of the tsunami was observed with the upward direction at every tidal station. The source area of the tsunami generated by the main shock (M=7.7, May 26, 1983) moved through width of 30km from the east margin of the aftershock area. The seabottom of this discrepancy region subsided, judging from the initial motion of the tsunami. According to the analysis of the tsunami and geodetic data, the main tsunami was generated by the 30° thrust fault slipping 4m. The seismic moment is 8×10^<27> dyne-cm.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128402","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hatori, Tokutaro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032931","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"羽鳥, 徳太郎"}],"nameIdentifiers":[{"nameIdentifier":"128401","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-26"}],"displaytype":"detail","filename":"ji0591006.pdf","filesize":[{"value":"526.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0591006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32931/files/ji0591006.pdf"},"version_id":"c4bac6b6-885c-41c6-89fe-14d53d3ea7d8"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"1983年日本海中部地震の余震に伴つた津波 : 付:本震による津波の発生機構","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"1983年日本海中部地震の余震に伴つた津波 : 付:本震による津波の発生機構","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4795","4796"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32931","relation_version_is_last":true,"title":["1983年日本海中部地震の余震に伴つた津波 : 付:本震による津波の発生機構"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:38:03.357318+00:00"}
