More than a hundred earthquakes, ranging from micro-earthquakes to moderate ones, have been registered during the total 270 hours recording time. 1) The activity of micro-earthquakes in and near Sagami Bay in June and December in 1967 was such that, when it is expressed by the number of earthquakes registered at a station for every 24 hours, and of which velocity amplitude is larger than 60μkine at the station and S-P time is less than 10 seconds, the frequency of earthquake registration was in average about 1～2 earthquakes for every 24 hours. 2) Simultaneous registration of these micro-earthquakes, of which S-P time is less than 10 seconds, both at the sea-bottom station and at a land station which were about 40km apart was only about 33%. 3) The homogeneity of micro-earthquake registration with respect to time was disturbed by the noises caused probably by the intermittent occurrenae of sea-bottom current.|新しく開発された磁気テープレコーダ方式を用いて,相模湾において1966年から1967年にわたり数回海底地震観測を行なつた.これらの観測実験は計器の試験および海底地震観測上の諸問題を調べると共に,1923年の関東大地震の震源域である相模湾における微小地震の活動を調べることを目的とした.実験は東京大学海洋研究所研究船淡青丸,および海上保安庁水路部測量船明洋の協力によつて行なわれた.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"130518","nameIdentifierScheme":"WEKO"}],"names":[{"name":"南雲, 昭三郎"}]},{"nameIdentifiers":[{"nameIdentifier":"130519","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小林, 平八郎"}]},{"nameIdentifiers":[{"nameIdentifier":"130520","nameIdentifierScheme":"WEKO"}],"names":[{"name":"是沢, 定之"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033424","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":"Nagumo, Shozaburo"}],"nameIdentifiers":[{"nameIdentifier":"130515","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kobayashi, Heihachiro"}],"nameIdentifiers":[{"nameIdentifier":"130516","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koresawa, Sadayuki"}],"nameIdentifiers":[{"nameIdentifier":"130517","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":"ji0464005.pdf","filesize":[{"value":"823.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0464005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33424/files/ji0464005.pdf"},"version_id":"c8ecc8a9-b1c6-4992-bb9a-6a88420c917e"}]},"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":"42.
