In 1983, two trenches, A and B, were excavated across geomorphologically estimated active faults, the Wakamiya and Osawa Faults, belonging to the ITL active fault system. The purpose of this trenching survey is to identify the precise position of fault traces and the nature of faults, and to establish the timing of faulting, particulaly the age of the latest event and recurrence interval of faulting. Both trenches are located at the base of the western slope of tectonic bulges, but trench A is on the middle of the bulge (Figs. 4 & 6) and trench B is on the southern end of the bulge (Figs. 5 & 7). Both trenches have similar direction, NEE-SWW, perpendicular to the fault trend (long axes of the bulges), and have similar scale, ca. 30m in length and ca. 3 m in depth, except for the eastern part of trench A (ca. 7 m in depth) (Table 1).","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"127741","nameIdentifierScheme":"WEKO"}],"names":[{"name":"RESEARCH GROUP FOR THE ITOSHIZU TECTONIC LINE ACTIVE FAULTS"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032812","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":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"糸静線活断層系発掘調査研究グループ"}],"nameIdentifiers":[{"nameIdentifier":"127740","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":"ji0634002.pdf","filesize":[{"value":"6.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0634002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32812/files/ji0634002.pdf"},"version_id":"2286e372-b712-450d-9ada-e711a61b61da"}]},"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":"糸静線活断層系中部,若宮,大沢断層の性格と第四紀後期における活動 : 富士見,茅野における発掘調査","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"糸静線活断層系中部,若宮,大沢断層の性格と第四紀後期における活動 : 富士見,茅野における発掘調査","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4748","4750"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32812","relation_version_is_last":true,"title":["糸静線活断層系中部,若宮,大沢断層の性格と第四紀後期における活動 : 富士見,茅野における発掘調査"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:30.283276+00:00"}
