Refraction seismic study using 10 OBS's and four tons of explosives indicated that the crust of the Middle Okinawa Trough has a 5km thick 6.0km/sec layer above a highly attenuating 6.8km/sec layer. Moho was not detected even at epicentral distances greater than 130 km. The crust was considered to be continental but low in Q in its lower part and the uppermost mantle to be anomalously low in both wave velocity and Q. Observations of natural earthquakes, carried out for about one month by 10 OBS's, detected highly active micro-seismicity in the area. Some OBS's recorded particular phases which suspect of reflections from magma sheets as well as particular waves similar to volcanic tremors.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128124","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nagumo, Shozaburo"}]},{"nameIdentifiers":[{"nameIdentifier":"128125","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kinoshita, Hajimu"}]},{"nameIdentifiers":[{"nameIdentifier":"128126","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kasahara, Junzo"}]},{"nameIdentifiers":[{"nameIdentifier":"128127","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ouchi, Toru"}]},{"nameIdentifiers":[{"nameIdentifier":"128128","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tokuyama, Hidekazu"}]},{"nameIdentifiers":[{"nameIdentifier":"128129","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Asamuma, Hinako"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032868","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":"千葉大学理学部"},{"subitem_text_value":"神戸大学理学部"},{"subitem_text_value":"東京大学海洋研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"南雲, 昭三郎"}],"nameIdentifiers":[{"nameIdentifier":"128116","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"木下, 肇"}],"nameIdentifiers":[{"nameIdentifier":"128117","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"笠原, 順三"}],"nameIdentifiers":[{"nameIdentifier":"128118","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大内, 徹"}],"nameIdentifiers":[{"nameIdentifier":"128119","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"徳山, 英一"}],"nameIdentifiers":[{"nameIdentifier":"128120","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"浅沼, 俊夫"}],"nameIdentifiers":[{"nameIdentifier":"128121","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"是澤, 定之"}],"nameIdentifiers":[{"nameIdentifier":"128122","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"秋吉, 日奈子"}],"nameIdentifiers":[{"nameIdentifier":"128123","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":"ji0612002.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0612002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32868/files/ji0612002.pdf"},"version_id":"80da1d37-4c2d-4b03-812a-aff1e79b8c75"}]},"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":"Report on DELP 1984 Cruises in the Middle Okinawa Trough : Part II : Seismic Structural Studies","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Report on DELP 1984 Cruises in the Middle Okinawa Trough : Part II : Seismic Structural Studies","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4773","4774"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32868","relation_version_is_last":true,"title":["Report on DELP 1984 Cruises in the Middle Okinawa Trough : Part II : Seismic Structural Studies"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:47.471555+00:00"}
