Travel times of the incidence and reflected waves were obtained by using the Normalized Input-Output Minimization (NIOM) method, and 3-D angles of propagation directions were estimated. The estimated directions correlated well with the theoretical ones calculated from the epicenter coordinates, focal depth, and the velocity distribution in the earth's crust. However, the estimated angles (0-20 degrees) from the ertical\naxis for the observed waves were somewhat larger than the theoretical ones (0-4 degrees).","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人土木学会"}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.2208/jscej.2005.780_41","subitem_relation_type_select":"DOI"}}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18827187","subitem_source_identifier_type":"ISSN"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"YANG, Zhongyuan"},{"subitem_text_value":"Kawakami, Hideji"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002678"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"埼玉大学教授地圏科学研究センター"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"&EMPTY&"},{"subitem_text_value":"Geosphere Research Institute of Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2005-1"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"楊, 仲元"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川上, 英二"},{"creatorName":"カワカミ, ヒデジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002678.pdf","filesize":[{"value":"867.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002678.pdf","url":"https://sucra.repo.nii.ac.jp/record/14351/files/A1002678.pdf"},"version_id":"0e9b67f2-bd6d-4b51-87a9-2b93d9c794b6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"seismic wave","subitem_subject_scheme":"Other"},{"subitem_subject":"propagation direction","subitem_subject_scheme":"Other"},{"subitem_subject":"array observation","subitem_subject_scheme":"Other"},{"subitem_subject":"ground motion","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"アレー観測データに基づく地表面近傍での地震波動の伝播方向の推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アレー観測データに基づく地表面近傍での地震波動の伝播方向の推定"}]},"item_type_id":"119","owner":"3","path":["242"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-06-02"},"publish_date":"2008-06-02","publish_status":"0","recid":"14351","relation_version_is_last":true,"title":["アレー観測データに基づく地表面近傍での地震波動の伝播方向の推定"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:00:23.389111+00:00"}
