Thus, a tsunami simulation for these two cases has been carried out numerically by the finite differnce method (leap-frog method) on the basis of shallow water equations. Computational mesh sizes were decreased from the open sea to the innermost part of the bay in several steps. The movement of the water front due to inundation on dry land was taken into consideration only in the innermost part of Ofunato Bay. In the case of the 1960 Chile tsunami the incoming wave patterns at the eastern open sea boundary located about 150 km from the coast of Honshu were inferred from the obsereved tsunami records at Miyagi-Enoshima, a small island just off the main coast of northeastern Japan. A better simulation of the overall inundation height distribution for this tsunami was obtained by using a somewhat higher value of the effective friction coefficient on land area, f=1.0, than the value (f=0.5) previously used in the simulation made in Owase City, Mie Prefecture for the tsunami of 1944. For the 1933 Sanriku tsunami, a seismic fault model already published was used as the tsunami source. Simulated tsunami inundation heights agreed fairly well with the measured data in most parts of the investigated area. In this simulation, the local variation of the maximun water level was remarkable because the prevailing period of this tsunami was rather short (8 to 15 min).","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128537","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Aida, Isamu"}]},{"nameIdentifiers":[{"nameIdentifier":"128538","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hatori, Tokutaro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032967","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":"128535","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"羽鳥, 徳太郎"}],"nameIdentifiers":[{"nameIdentifier":"128536","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":"ji0581006.pdf","filesize":[{"value":"790.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0581006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32967/files/ji0581006.pdf"},"version_id":"f14e1a50-1d80-4ad4-99f9-f722817d50dc"}]},"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":"6. 大船渡市街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":"6. 大船渡市街に遡上した津波の数値実験","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4805","4806"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32967","relation_version_is_last":true,"title":["6. 大船渡市街に遡上した津波の数値実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T03:51:50.404246+00:00"}
