The axial symmetry was assumed and the disturbances were expressed as the sum of contribution of about 600 normal mode oscillations. The theoretical seismograms thus obtained show the following remarkable features. 1) The arrival times of body waves identified on the theoretical seismogram coincide well with the theoretically calculated travel time. 2) The fundamental mode contributes to the surface waves most, while the higher modes are closely connected with the phases of body waves. 3) Surface waves end abruptly and a calm follows, which fact can be inferred from the shape of the group velocity curve with a minimum value. Non-dimensional frequency, phase and group velocities of surface wave, common spectrum as a function of n and the travel time curve of various phases are also given in the figures.","subitem_description_type":"Abstract"},{"subitem_description":"1.筆者らはさきに,弾性球を伝わる捩れ波を球のいろいろなモードの固有捩れ振動の和として表わし,実際の地震によく似た理論地震記象を求めた.今回は同様な方法を用い,等方等質弾性球の極附近に半径方向の力が加わる場合の変位を,球面上の数点で計算した.2.理論地震記象をより精度の高いものとするために,筆者らが前に求めた固有振動数に,i=6～9,n≧0;i=1～5,n＞60に対する固有振動数を追加計算した.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"131571","nameIdentifierScheme":"WEKO"}],"names":[{"name":"宇佐美, 龍夫"}]},{"nameIdentifiers":[{"nameIdentifier":"131572","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐藤, 泰夫"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033679","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":"Earthquake Research Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"USAMI, Tatsuo"}],"nameIdentifiers":[{"nameIdentifier":"131569","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SATO, Yasuo"}],"nameIdentifiers":[{"nameIdentifier":"131570","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":"ji0422001.pdf","filesize":[{"value":"628.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0422001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33679/files/ji0422001.pdf"},"version_id":"d4863fdf-8255-4fb8-9675-c77131b6bae3"}]},"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":"15.
