Wakayama City is being considered as one of the drilling sites, because earthquake swarms one to several kilometers deep occur there frequently. We expect to make continuous geophysical observations in the brehole penetrating the focal depths. A gravity survey was conducted at 115 stations in Wakayama City with a LaCoste-Romberg gravimeter in order to search for an optimum drilling site. The gravity high is in most cases found in an area of very shallow focal depths. Taking the obtained Bouguer anomaly into account, we conclude that the gravity high located on the eastern foot of Mt. Nagusa is the best site for drilling.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127763","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hagiwara, Yukio"}]},{"nameIdentifiers":[{"nameIdentifier":"127764","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okubo, Shuhei"}]},{"nameIdentifiers":[{"nameIdentifier":"127765","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakamura, Masao"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032817","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":"萩原, 幸男"}],"nameIdentifiers":[{"nameIdentifier":"127760","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大久保, 修平"}],"nameIdentifiers":[{"nameIdentifier":"127761","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中村, 正夫"}],"nameIdentifiers":[{"nameIdentifier":"127762","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":"ji0633004.pdf","filesize":[{"value":"575.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0633004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32817/files/ji0633004.pdf"},"version_id":"564c431d-a4ea-4f1a-a4d0-d39f1ddde7de"}]},"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":"和歌山平野の重力調査 : 学術ボーリング候補地の探査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"和歌山平野の重力調査 : 学術ボーリング候補地の探査","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4751","4752"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32817","relation_version_is_last":true,"title":["和歌山平野の重力調査 : 学術ボーリング候補地の探査"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:38:03.529625+00:00"}
