Izu-Oshima is an active basaltic volcano repeating major eruptions in historic times, and often produced low viscosity lavas containing much magnetic minerals. In 1986, the first eruption started from the summit crater of Mihara-yama. Successively, flank fissure eruptions occurred within and outside the caldera and forced the evacuation of habitants. The Izu-Oshima volcano is located near the triple junction of the Pacific, Philippine Sea and Eurasian plates, and at the northeastern border of the subducting Philippine Sea plate. Consequently, the activity of Izu-Oshima volcano is closely related to the crustal activity at the Izu and off Boso peninsulas. The main object of OVO is to conduct comprehensive studies on the activity of Izu-Oshima volcano and the surrounding areas. The current projects include (1) study of volcanic phenomena and its application to eruption prediction, (2) tomographic study of the subterranean structure of Izu-Oshima volcano and the surrounding areas and (3) relation between the volcanic activity and the surrounding tectonic activity. In the 1986-1987 eruptions, a comprehensive cooperation among the related scientists was very effective in obtaining much high-quality data to promote researches on precursors and mechanisms of the eruption. After the eruption, the networks of seismometric, geodetic and electromagnetic observations have been strengthened to perform basic researches on the magma transport system of Izu-Oshima volcano. The geodetic observation has revealed an inflation of the volcano, suggesting a continuous magma supply from depths toward the next eruption in future.","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":"72200","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAKASHITA, Shikou"}]},{"nameIdentifiers":[{"nameIdentifier":"72201","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIMOMURA, Takafumi"}]},{"nameIdentifiers":[{"nameIdentifier":"72202","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MIKADA, Hitoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"72203","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Hidefumi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032291","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":"火山噴火予知研究推進センター伊豆大島火山観測所"},{"subitem_text_value":"火山噴火予知研究推進センター(現在，地震火山災害部門)"},{"subitem_text_value":"火山噴火予知研究推進センター，(東京大学地震研究所)"},{"subitem_text_value":"Izu-Oshirna Volcano Observatory， Volcano Research Center"},{"subitem_text_value":"VolcanoResearch Center (now al Division of Disaster Mitigation Science)"},{"subitem_text_value":"VolcanoResearch Cenler，(Earthquake Research Institute，Universily of Tokyo)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"坂下, 至功"}],"nameIdentifiers":[{"nameIdentifier":"72196","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"下村, 高史"}],"nameIdentifiers":[{"nameIdentifier":"72197","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"三ケ田, 均"}],"nameIdentifiers":[{"nameIdentifier":"72198","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡辺, 秀文"}],"nameIdentifiers":[{"nameIdentifier":"72199","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":"01_007-017.pdf","filesize":[{"value":"19.8MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"01_007-017.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32300/files/01_007-017.pdf"},"version_id":"548b5f35-522a-4140-b46d-ae2a7fd3132d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Izu-Oshima volcano","subitem_subject_scheme":"Other"},{"subitem_subject":"seismic observations","subitem_subject_scheme":"Other"},{"subitem_subject":"geodetic observations","subitem_subject_scheme":"Other"},{"subitem_subject":"geoelectromagnetic observations","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":"伊豆大島火山観測所における火山観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"伊豆大島火山観測所における火山観測","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4497","4498"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32300","relation_version_is_last":true,"title":["伊豆大島火山観測所における火山観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:26.926875+00:00"}
