We detected many earthquake swarms by routine observation of Earthquake Observation Center, Earthquake Research Institute. This paper reports those seismic activities in the area during the period from November 1993 to January 1997. This area is divided into four active regions. The Ashio region, lying along the Uchinokomori-fault, had the remarkable activity in the period. The earthquake swarm occurred at the bending part of the fault at first on February 1994. In the following three years, the swarms gradually migrated from the north to the south along the lineament of the fault, accompanying many microearthquakes, and then spread toward the east and the west. Finally, those microearthquakes filled up the area of 10x3 km along the Uchinokomori-fault.","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":"72142","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HAGIWARA, Hiroko"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032280","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":"AA11286807","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":"地震地殻変動観測センター, (東京大学地震研究所)"},{"subitem_text_value":"Earthquake Observation Centεr, (Earthquake Research Institute, University of Tokyo)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"萩原, 弘子"}],"nameIdentifiers":[{"nameIdentifier":"72141","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":"02_043-072.pdf","filesize":[{"value":"45.8MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"02_043-072.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32289/files/02_043-072.pdf"},"version_id":"19249a61-375d-4127-b822-250a3457410e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Nikko-Ashio","subitem_subject_scheme":"Other"},{"subitem_subject":"microearthquake","subitem_subject_scheme":"Other"},{"subitem_subject":"earthquαke swarm","subitem_subject_scheme":"Other"},{"subitem_subject":"Uchinokomori-fault","subitem_subject_scheme":"Other"},{"subitem_subject":"law frequency earthquake","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":"日光・足尾地域の地震活動 : 1993年11月～1997年1月","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"日光・足尾地域の地震活動 : 1993年11月～1997年1月","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4495","4496"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32289","relation_version_is_last":true,"title":["日光・足尾地域の地震活動 : 1993年11月～1997年1月"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:05:45.441768+00:00"}
