The focal process of the Japan Sea Earthquake is summarized as follows: 1) the rupture velocity, source duration time, and  fault length are estimated to be about 2.4km/sec, 42 seconds, and 100km, respectively, 2) assuming the spatial distance of 35km between two subevents, the main shock forms the multiple shock with a time delay of 24.5 seconds. The predominant excitation of the Rayleigh wave at a period near 10 seconds, associated with long duration, is caused by the factor that the main shock occurred at the shallow part in the oceanic lithosphere.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128398","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshida, Mitsuru"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032929","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_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 満"}],"nameIdentifiers":[{"nameIdentifier":"128397","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":"ji0591004.pdf","filesize":[{"value":"597.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0591004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32929/files/ji0591004.pdf"},"version_id":"dcf1c074-3ded-4312-ba85-fa0dcbba702b"}]},"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5月26日日本海中部地震による表面波 : レイリー波水平成分の生成と震源メカニズム","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"1983年5月26日日本海中部地震による表面波 : レイリー波水平成分の生成と震源メカニズム","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":"32929","relation_version_is_last":true,"title":["1983年5月26日日本海中部地震による表面波 : レイリー波水平成分の生成と震源メカニズム"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:49.706129+00:00"}
