The area under consideration includes two short distance (3-5km) base line networks (Miura and Boso) and two intermediate distance  (10-15km) base line networks (Uraga and Boso). Several times surveys have been made until 1983 with various intervals of one to six years. Analysis of data from the twenty years'work has yielded the following results. (1) Base lines of intermediate distances show general contractions. The maximum principal strain rate in the selected three base lines is NNW contraction at a rate of about 6×10^<-7>/yr. This is consistent with the GSI's data from 1925 to 1971. (2) Base lines of short distances show a rather complicated pattern which is not always consistent with the results obtained from the longer base lines. Land movement in a very local scale is suspected as a possible cause of these inconsistencies.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128467","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsumoto, Shigeo"}]},{"nameIdentifiers":[{"nameIdentifier":"128468","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hirata, Yasuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"128469","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kato, Teruyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"128470","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Shigeru"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032947","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":"東京大学地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松本, 滋夫"}],"nameIdentifiers":[{"nameIdentifier":"128463","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平田, 安廣"}],"nameIdentifiers":[{"nameIdentifier":"128464","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加藤, 照之"}],"nameIdentifiers":[{"nameIdentifier":"128465","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡辺, 茂"}],"nameIdentifiers":[{"nameIdentifier":"128466","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":"ji0583009.pdf","filesize":[{"value":"587.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0583009.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32947/files/ji0583009.pdf"},"version_id":"638459b6-2135-4123-9125-ce340194d0f9"}]},"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":"30. 三浦半島,房総半島及び浦賀水道における光波測量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"30. 三浦半島,房総半島及び浦賀水道における光波測量","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4801","4802"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32947","relation_version_is_last":true,"title":["30. 三浦半島,房総半島及び浦賀水道における光波測量"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:29.944861+00:00"}
