The signal from the ACROSS is routinely monitored by 15 permanent stations and 4 temporal stations in Sakurajima volcano. We successfully observed the ACROSS signal at each station and could detect temporal variation of the transfer function (TF). Because the temporal variation of later phases in the TF was obviously larger than that in the early phases, we inferred that the temporal variation of the later phases reflected the temporal change of the structure in deep regions beneath Sakurajima volcano. We also found that the temporal variation of the TF is correlated with volcanic activity such as the daily volcanic eruptions and crustal deformation in Sakurajima Island.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学","subitem_publisher_language":"ja"},{"subitem_publisher":"Kagoshima University","subitem_publisher_language":"en"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"23340130"}]},"item_8_version_type_14":{"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":"宮町, 宏樹","creatorNameLang":"ja"},{"creatorName":"MIYAMACHI, Hiroki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"34086","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000030182041","nameIdentifierScheme":"NRID","nameIdentifierURI":" "}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-31"}],"displaytype":"detail","filename":"23340130_宮町宏樹.pdf","filesize":[{"value":"166.2 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"23340130_宮町宏樹.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/13243/files/23340130_宮町宏樹.pdf"},"version_id":"9eaaea50-914b-4511-b36c-6dd5c5a403cd"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"火山","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"桜島","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"アクロス","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"伝達関数","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"マグマ","subitem_subject_language":"ja","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"弾性波アクロスによる桜島火山マグマ動的変化の検出とその要因に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"弾性波アクロスによる桜島火山マグマ動的変化の検出とその要因に関する研究","subitem_title_language":"ja"},{"subitem_title":"Stusy of detection of dynamic change of magma transport process by using ACROSS and its cause, in Sakurajima volcano","subitem_title_language":"en"}]},"item_type_id":"8","owner":"18","path":["79"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-05-19"},"publish_date":"2015-05-19","publish_status":"0","recid":"13243","relation_version_is_last":true,"title":["弾性波アクロスによる桜島火山マグマ動的変化の検出とその要因に関する研究"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-05-23T02:18:14.647121+00:00"}
