This investigation will improve information needed for seismic hazards from inter-plate mega-thrust earthquakes and intra-slab earthquakes for the Kanto region.  Unification of earthquake datasets, if available, would contribute to creating a database that is devoted to in-depth research on the regional plate structure.  Currently available datasets for the Kanto region are three regional and nationwide catalogs: (a) NIED catalog: earthquake catalog based on the Kanto-Tokai Observational Network maintained by National Research Institute for Earth Science and Disaster Prevention; (b) ERI catalog: catalog including micro-earthquakes detected mainly by the seismic network maintained by Earthquake Research Institute, University of Tokyo with special focus on the Kanto area; (c) JMA catalog: catalog including nationwide seismicity monitored by Japan Meteorological Agency.  Before starting to unify the catalogs it is necessary to get a better understanding of the statistical properties of earthquakes for each catalog.  Here, we report the results of statistical analyses to characterize data quality for individual catalogs.  Our approach is based on the frequency-magnitude distribution of earthquakes, daily variations of earthquake frequency, and completeness magnitude study.  Reported statistical characteristics will allow us to move toward unifying earthquake catalogs.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"123645","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nanjo, Kazuyoshi Z."}]},{"nameIdentifiers":[{"nameIdentifier":"123646","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tsuruoka, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"123647","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kasahara, Keiji"}]},{"nameIdentifiers":[{"nameIdentifier":"123648","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sakai, Shinichi"}]},{"nameIdentifiers":[{"nameIdentifier":"123649","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hirata, Naoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"123650","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Obara, Kazunari"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032439","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":"51.1","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"},{"subitem_text_value":"独立行政法人防災科学技術研究所 "}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"楠城, 一嘉"}],"nameIdentifiers":[{"nameIdentifier":"123639","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鶴岡, 弘"}],"nameIdentifiers":[{"nameIdentifier":"123640","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"笠原, 敬司"}],"nameIdentifiers":[{"nameIdentifier":"123641","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"酒井, 慎一"}],"nameIdentifiers":[{"nameIdentifier":"123642","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平田, 直"}],"nameIdentifiers":[{"nameIdentifier":"123643","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小原, 一成"}],"nameIdentifiers":[{"nameIdentifier":"123644","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":"IHO84209.pdf","filesize":[{"value":"1.1MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"IHO84209.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32439/files/IHO84209.pdf"},"version_id":"1878fae1-e12e-48f5-8c1f-6ff074d1cd1c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Earthquake","subitem_subject_scheme":"Other"},{"subitem_subject":"seismicity","subitem_subject_scheme":"Other"},{"subitem_subject":"statistics","subitem_subject_scheme":"Other"},{"subitem_subject":"Tokyo metropolitan area","subitem_subject_scheme":"Other"},{"subitem_subject":"data quality ","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":"首都圏の地震カタログの統合へ向けた品質評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"首都圏の地震カタログの統合へ向けた品質評価","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4575","4576"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-02-17"},"publish_date":"2010-02-17","publish_status":"0","recid":"32439","relation_version_is_last":true,"title":["首都圏の地震カタログの統合へ向けた品質評価"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:28.888884+00:00"}
