(Earthquake Research Institute). Time distance data of direct and refracted waves are correlated with the data of reflections to evaluate seismic wave velocities in the earth's crust. An interpretation of the time distance data is represented for the reflections from the Conrad and the Mohorovicic discontinuities. The depth of the Conrad discontinuity can be measured as 20-24 km in the western part of the Kii Peninsula with a possible inclination dipping to the west. The depth of the Mohorovicic discontinuity can be estimated as about 30km in the inland area of the Kii Peninsula. Seismic wave velocities in the upper and the lower crustal layers are estimated as 5.80 km/sec and 6.80 km/sec for the P-waves and 3.46km/sec and 4.05 km/sec for the S-waves respectively. The velocities of the Pg and Pn waves are determined as 5.8 km/sec and 7.9 km/sec respectively from the network observations at the observatory.|和歌山微小地震観測所の定常観測資料にもとづいて地殻内部の不連続面での反射波および屈折波の走時解析を行ない紀伊半島の地殻構造との関係を調べた.以下その結果を要約する.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"129852","nameIdentifierScheme":"WEKO"}],"names":[{"name":"溝上, 恵"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033259","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":"Mizoue, Megumi"}],"nameIdentifiers":[{"nameIdentifier":"129851","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":"ji0491004.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0491004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33259/files/ji0491004.pdf"},"version_id":"6622251e-9085-4576-851a-c7b2bb2782bb"}]},"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":"4.
