Based on the omega-square source model, constant stress drop scaling, constant Q, and instrumental response, we calculated a typical waveform for each event with a given seismic moment and MW to estimate its ME. This leads to theoretical relationships, which show 1)saturation for MW>6, 2)overestimation of ME for 3<MW<5, and 3) underestimation of ME for MW<2. Under MW 2, ME scales with 1.5MW, which may affect the estimation of b-value of the Gutenberg and Richter equation. Catalogue values of ME and MW for small and medium events show the predicted trend.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"125853","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ide, Satoshi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032576","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"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"井出, 哲"}],"nameIdentifiers":[{"nameIdentifier":"125852","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":"ji0774002.pdf","filesize":[{"value":"440.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0774002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32576/files/ji0774002.pdf"},"version_id":"efff2106-867f-4c70-9fe2-c7993a1c3cc6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ERI magnitude","subitem_subject_scheme":"Other"},{"subitem_subject":"moment magnitude","subitem_subject_scheme":"Other"},{"subitem_subject":"omega-square model","subitem_subject_scheme":"Other"},{"subitem_subject":"constant stress drop scaling","subitem_subject_scheme":"Other"},{"subitem_subject":"constant Q","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":"地震研究所マグニチュードとモーメントマグニチュードの関係の理論的考察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"地震研究所マグニチュードとモーメントマグニチュードの関係の理論的考察","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4630","4632"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32576","relation_version_is_last":true,"title":["地震研究所マグニチュードとモーメントマグニチュードの関係の理論的考察"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:37.262951+00:00"}
