However a small number of studies focus on structures beneath backarc basins and marginal seas because of few seismic stations there. The present study focused on the structure beneath Okinawa trough. The Philippine Sea plate is subducting along the Ryukyu trench, forming the Ryukyu arc. The Okinawa trough is a back-arc basin behind the Ryukyu arc and is considered to be a rift zone. We inferred one-dimensional shearwave velocity structure of crust and uppermost mantle beneath the Okinawa trough. We also inferred one beneath the East China Sea continental shelf where is not a rift zone. We measured phase velocities of Rayleigh and Love waves. We then inverted the phase velocity dispersion curves for the one-dimensional shear-wave average structures along the paths by genetic algorithm. The shear wave velocities in the lower crust beneath the Okinawa trough is lower than that beneath the continental shelf. It may suggest magma intrusion in the lower crust. The shear wave velocities just below the Moho beneath the Okinawa trough is significantly lower than that beneath the continental shelf. It may suggest partial melting due to upwelling beneath the Okinawa trough. The SV velocities beneath the Okinawa trough are lower than SH velocities, while SV and SH velocities beneath continental shelf are similar to each other. These radial anisotropies beneath the Okinawa trough may be caused by the shape of the cracks or preferred orientations of mantle minerals.", "subitem_description_type": "Other"}]}, "item_7_full_name_2": {"attribute_name": "著者よみ", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "72313", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "コバヤシ, レイジ"}]}, {"nameIdentifiers": [{"nameIdentifier": "72314", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "エトウ, アヤノ"}]}, {"nameIdentifiers": [{"nameIdentifier": "72315", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "タサキ, ナオコ"}]}, {"nameIdentifiers": [{"nameIdentifier": "72316", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "フクダ, ケイスケ"}]}]}, "item_7_full_name_3": {"attribute_name": "別言語の著者", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "72317", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "KOBAYASHI, Reiji"}]}, {"nameIdentifiers": [{"nameIdentifier": "72318", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ETOH, Ayano"}]}, {"nameIdentifiers": [{"nameIdentifier": "72319", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "TASAKI, Naoko"}]}, {"nameIdentifiers": [{"nameIdentifier": "72320", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "FUKUDA, Keisuke"}]}]}, "item_7_publisher_23": {"attribute_name": "公開者・出版者", "attribute_value_mlt": [{"subitem_publisher": "鹿児島大学"}]}, "item_7_source_id_9": {"attribute_name": "NII書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AA11246904", "subitem_source_identifier_type": "NCID"}]}, "item_7_subject_15": {"attribute_name": "NDC", "attribute_value_mlt": [{"subitem_subject": "453", "subitem_subject_scheme": "NDC"}]}, "item_7_text_24": {"attribute_name": "公開者よみ", "attribute_value_mlt": [{"subitem_text_value": "カゴシマ ダイガク"}]}, "item_7_text_25": {"attribute_name": "公開者別名", "attribute_value_mlt": [{"subitem_text_value": "Kagoshima University"}]}, "item_7_text_30": {"attribute_name": "NIIタイプ", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_7_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": "小林, 励司"}], "nameIdentifiers": [{"nameIdentifier": "72309", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "衛藤, 綾乃"}], "nameIdentifiers": [{"nameIdentifier": "72310", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "田崎, 菜央子"}], "nameIdentifiers": [{"nameIdentifier": "72311", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "福田, 圭佑"}], "nameIdentifiers": [{"nameIdentifier": "72312", "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": "2016-10-27"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "48_p7-14.pdf", "filesize": [{"value": "929.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 929000.0, "url": {"label": "48_p7-14.pdf", "url": "https://ir.kagoshima-u.ac.jp/record/3136/files/48_p7-14.pdf"}, "version_id": "4d057360-d2df-4502-80dd-dcdd950d6f5b"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "the Okinawa trough", "subitem_subject_scheme": "Other"}, {"subitem_subject": "back arc", "subitem_subject_scheme": "Other"}, {"subitem_subject": "rift zone", "subitem_subject_scheme": "Other"}, {"subitem_subject": "surface wave", "subitem_subject_scheme": "Other"}, {"subitem_subject": "shear-wave velocity structure", "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": "表面波位相速度から推定される沖縄トラフにおける1次元S波速度構造", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "表面波位相速度から推定される沖縄トラフにおける1次元S波速度構造"}]}, "item_type_id": "7", "owner": "3", "path": ["53", "5069"], "permalink_uri": "http://hdl.handle.net/10232/26363", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-03-30"}, "publish_date": "2016-03-30", "publish_status": "0", "recid": "3136", "relation": {}, "relation_version_is_last": true, "title": ["表面波位相速度から推定される沖縄トラフにおける1次元S波速度構造"], "weko_shared_id": 3}
