We have been measuring electromagnetic signals in ELF frequency range all over Japan in order to predict earthquakes. Because the observed data is very huge, it is difficult to discriminate anomalous signals manually. In this paper, we propose the method to detect anomalous signals by focusing on errors between LPC models and observed signals. On the other hand, it is effective to investigate the generation mechanisms of precursory emissions employing the simultaneous observations both onboard satellite and on the ground. At the satellite altitude (>400km), it is necessary to estimate the possibility that the ELF radio waves emitted from the epicenter can be propagated into the upper ionosphere with enough field strength to be observable. This paper presents some preliminary numerical calculations for field structure of ELF (223Hz) radio waves between the earth and the ionosphere and in the upper ionosphere up to 1,000km.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"共催: 日本学術会議","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA)","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064113039","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10324210","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"中部大学"},{"subitem_text_value":"中部大学"},{"subitem_text_value":"中部大学"},{"subitem_text_value":"中部大学"},{"subitem_text_value":"名古屋工業大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Chubu University"},{"subitem_text_language":"en","subitem_text_value":"Chubu University"},{"subitem_text_language":"en","subitem_text_value":"Chubu University"},{"subitem_text_language":"en","subitem_text_value":"Chubu University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya Institute of Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"畑, 雅恭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"馬場, 清秀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤井, 隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"太田, 健次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"内匠, 逸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hata, Masayasu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Baba, Kiyohide","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujii, Takasi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ota, Kenji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takumi, Ichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-20"}],"displaytype":"detail","filename":"64113039.pdf","filesize":[{"value":"493.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64113039.pdf","url":"https://jaxa.repo.nii.ac.jp/record/13656/files/64113039.pdf"},"version_id":"5da739f4-44d2-4b18-b952-4e82e8b08efc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Precursor, Environmental Electromagnetic Radiation, ELF, LPC model, Satellite observation, Ionosphere Penetration","subitem_subject_language":"en","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"極超長波（ELF Waves）地球放射波の電離層突き抜け特性と衛星による観測について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"極超長波（ELF Waves）地球放射波の電離層突き抜け特性と衛星による観測について"}]},"item_type_id":"5","owner":"1","path":["1645","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"13656","relation_version_is_last":true,"title":["極超長波（ELF Waves）地球放射波の電離層突き抜け特性と衛星による観測について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T05:48:11.744852+00:00"}
