The tsunami source models by AIDA (1981) are available for these tsunamis. The effective friction coefficient is assumed to be 1.0 for the most crowded housing areas and 0.2 for other urban areas. For the 1946 Nankai tsunami, the distribution of simulated inundation heights at Yuasa and Hiro in the innermost part of Yuasa Bay is in good agreement with the actual heights obtained by a field survey of traces of inundated water or the evidences pointed out by the residents. For the 1854 Ansei-Nankai tsunami, a 15% larger slip of fault than that of the published model was required to fit the simulated results to the inundation heights estimated from old documents. For the 1946 tsunami, the standard deviation of differnces between the surveyed and the simulated inundation heights are calculated in the 4 separated areas. They are 8.2 to 13.3% of the average value of surveyed heights in each area. Averaging the results of three simulations: the 1944 Tonankai tsunami in Owase City, the 1960 Chile tsunami in Ofunato City and the present one, it is found that the relative standard error of the simulated inundation heights is about 10% with respect to the average value of surveyed data.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128451","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Aida, Isamu"}]},{"nameIdentifiers":[{"nameIdentifier":"128452","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hatori, Tokutaro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032944","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":"相田, 勇"}],"nameIdentifiers":[{"nameIdentifier":"128449","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽鳥, 徳太郎"}],"nameIdentifiers":[{"nameIdentifier":"128450","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":"ji0583006.pdf","filesize":[{"value":"930.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0583006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32944/files/ji0583006.pdf"},"version_id":"f35760a1-c3cd-4d76-8f4a-c4052cef0803"}]},"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":"27. 和歌山県,湯浅・広川両町に遡上した津波の数値実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"27. 和歌山県,湯浅・広川両町に遡上した津波の数値実験","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4801","4802"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32944","relation_version_is_last":true,"title":["27. 和歌山県,湯浅・広川両町に遡上した津波の数値実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:50.091455+00:00"}
