Usu. Comparing the gravity values acquired by previous measurements in June 1993, we detected significant gravity changes presumably associated with the magma movement. The largest change detected as of May 2000 was - 820μgal at the southern rim of the summit. Both gravity and height changes were successfully reproduced by prescribing a shallow inflation source and a deeper deflation source at depths of 2,000 and 3,000 meters, respectively. Total intruded mass flux is estimated to be 3.6×1010kg. We constructed an absolute gravity network consisting of three sites around Toya lake, and precisely determined absolute gravity values. Moreover, from 16 May to 29 June, we took continuous absolute gravity measurements at Usu volcano observatory, and detected a significant post eruptive gravity change. The absolute gravity continued to decrease by 10μgal until around 25 May when it began to increase After that, the absolute gravity gradually recovered to 10μgal for one month. We can interpret the inferred post-eruptive gravity changes as a continuing crustal uplift followed by a commence of the land subsidence.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"126303","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Furuya, Masato"}]},{"nameIdentifiers":[{"nameIdentifier":"126304","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ohki, Yuko"}]},{"nameIdentifiers":[{"nameIdentifier":"126305","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okubo, Shuhei"}]},{"nameIdentifiers":[{"nameIdentifier":"126306","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Maekawa, Tokumitsu"}]},{"nameIdentifiers":[{"nameIdentifier":"126307","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Oshima, Hiromitsu"}]},{"nameIdentifiers":[{"nameIdentifier":"126308","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shimizu, Hiroshi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032619","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":"東京大学地震研究所"},{"subitem_text_value":"北海道大学理学研究科"},{"subitem_text_value":"九州大学理学研究科"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古屋, 正人"}],"nameIdentifiers":[{"nameIdentifier":"126297","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大木, 裕子"}],"nameIdentifiers":[{"nameIdentifier":"126298","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大久保, 修平"}],"nameIdentifiers":[{"nameIdentifier":"126299","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"前川, 徳光"}],"nameIdentifiers":[{"nameIdentifier":"126300","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大島, 弘光"}],"nameIdentifiers":[{"nameIdentifier":"126301","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"清水, 洋"}],"nameIdentifiers":[{"nameIdentifier":"126302","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":"ji0762006.pdf","filesize":[{"value":"920.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0762006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32619/files/ji0762006.pdf"},"version_id":"c8b0c5f5-199f-4097-a5a8-315d777a71d5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"gravity change","subitem_subject_scheme":"Other"},{"subitem_subject":"volcanic eruption","subitem_subject_scheme":"Other"},{"subitem_subject":"absolute gravimetry","subitem_subject_scheme":"Other"},{"subitem_subject":"point source","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":"有珠山2000年噴火活動に対する緊急重力測定 : 絶対重力観測網の構築と噴火前後の重力変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"有珠山2000年噴火活動に対する緊急重力測定 : 絶対重力観測網の構築と噴火前後の重力変化","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4645","4646"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32619","relation_version_is_last":true,"title":["有珠山2000年噴火活動に対する緊急重力測定 : 絶対重力観測網の構築と噴火前後の重力変化"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T05:17:16.638100+00:00"}
