Many tephra layers are widely distributed over the eastern foot of Kirishima testifying to the intensity of the pyroclastic eruptions ranging from powerful plinian to milder strombolian activities. Eighteen volcanoes are formed, some of which are polygenetic and others monogenetic, since 22,000 years ago (22ka). Total mass of erupted material from the Kirishima volcano during the past 22,000 years is estimated to be 23×10^＜12＞kg (tephra; 6.6×10^＜12＞kg, lava; 16.4×10^＜12＞kg). The activity of the Kirishima volcano for the past 22,000 years can be divided into three periods in terms of average magma discharge rate (i.e., 22-15ka; 7.8 ×10^8m^3/ky, 15-7ka; 0.4×10^8m^3/ky and 7ka to the present; 4.9×10^8m^3/ky) and eruptive style have changed with time from relatively effusive to more explosive type.","subitem_description_type":"Abstract"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Department of Geography, Tokyo Metropolitan University"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00200173","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03868710","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Imura, Ryusuke"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-04"}],"displaytype":"detail","filename":"20005-27-006.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20005-27-006.pdf","url":"https://tokyo-metro-u.repo.nii.ac.jp/record/2898/files/20005-27-006.pdf"},"version_id":"841012d6-cd3b-4a4d-9439-0be5e61077d1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Kirishima volcano","subitem_subject_scheme":"Other"},{"subitem_subject":"eruptive history","subitem_subject_scheme":"Other"},{"subitem_subject":"volcano-stratigraphy","subitem_subject_scheme":"Other"},{"subitem_subject":"magma discharge rate","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Eruptive history of the kirishima volcano during the past 22,000 years","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Eruptive history of the kirishima volcano during the past 22,000 years"}]},"item_type_id":"3","owner":"3","path":["550"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-11-30"},"publish_date":"2010-11-30","publish_status":"0","recid":"2898","relation_version_is_last":true,"title":["Eruptive history of the kirishima volcano during the past 22,000 years"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T18:25:49.600802+00:00"}
