As described by Nakamura and Tsuneishi (1967), many fissure zones consisting of small cracks were arranged en echelon in two main belts of northwest and northeast trend respectively. The former group of fissures is more remarkable and has offsets of as much as tens of centimeters left-laterally. The northeasterly trending faults are right-lateral. Both trends show some vertical components. These directions of fracture systems and senses of displacement agree with those expected from study of fault plane solutions for initial motions of the present earthquakes. Most of these fissures appeared on alluvial fans, although some extended to the adjacent mountains, which are made up of Miocene sedimentary and intrusive rocks.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"130890","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Matsuda, Tokihiko"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033508","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松田, 時彦"}],"nameIdentifiers":[{"nameIdentifier":"130889","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":"ji0452014.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0452014.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33508/files/ji0452014.pdf"},"version_id":"a03ca5e9-739a-4e5b-b1b8-f6931b93c64d"}]},"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":"松代地震断層の地質学的性質","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"松代地震断層の地質学的性質","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4933","4934"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33508","relation_version_is_last":true,"title":["松代地震断層の地質学的性質"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:29:35.463038+00:00"}
