Due to the path effect that the great circle paths of the long-period surface waves are predominantly located along the circum-Pacific seismic zone, the coefficients determined are somewhat larger and Q values lower than the standard ones. The Rayleigh wave attenuation is calculated on the basis of the amplitude spectral ratios of Rn+2IRn which are about 0.2, 0.35 and 0.5 for the periods 100, 200 and 300 seconds respectively. A relationship between the apparent characteristics of Q values versus the wave period and the errors made in the wave analysis is discussed.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128692","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshida, Mitsuru"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033006","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":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉田, 満"}],"nameIdentifiers":[{"nameIdentifier":"128691","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":"ji0564002.pdf","filesize":[{"value":"769.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0564002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33006/files/ji0564002.pdf"},"version_id":"24bf13d3-67f0-4e19-9888-ada70477aee3"}]},"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":"長周期レイリー波の減衰特性と位相速度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"長周期レイリー波の減衰特性と位相速度","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4818","4820"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"33006","relation_version_is_last":true,"title":["長周期レイリー波の減衰特性と位相速度"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:36.121099+00:00"}
