The careful adjustment of leveling instruments and a well-designed survey scheme have resulted in the considerable improvement of measurement accuracy to the level of 0.5 mm/km, which is less than the quarter of the first order leveling surveys. On the soft ground and asphalt roads, a sufficient number of supplemental benchmarks installed on stable base are very effective in the accidental subsidence of leveling staffs.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜論説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72047","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOYAMA, Etsuro"}]},{"nameIdentifiers":[{"nameIdentifier":"72048","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TAKEDA, Toyotaro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032259","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":"AA1144042X","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"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":"東京大学地震研究所火山噴火予知研究推進センター浅間火山観測所"},{"subitem_text_value":"火山噴火予知研究推進センター"},{"subitem_text_value":"Asama Volcano Observatory"},{"subitem_text_value":"Volcano Research Center, Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小山, 悦郎"}],"nameIdentifiers":[{"nameIdentifier":"72045","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"竹田, 豊太郎"}],"nameIdentifiers":[{"nameIdentifier":"72046","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":"2017-06-12"}],"displaytype":"detail","filename":"04_001-006.pdf","filesize":[{"value":"5.5MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"04_001-006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32268/files/04_001-006.pdf"},"version_id":"7599e27a-e6e3-4834-b11c-d0476657eff8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"leveling","subitem_subject_scheme":"Other"},{"subitem_subject":"ground deformation","subitem_subject_scheme":"Other"},{"subitem_subject":"Asama volcano","subitem_subject_scheme":"Other"}]},"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":"浅間火山における水準測量方法の工夫とその成果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"浅間火山における水準測量方法の工夫とその成果","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4491","4492"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32268","relation_version_is_last":true,"title":["浅間火山における水準測量方法の工夫とその成果"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:07:37.760398+00:00"}
