The damage percentages suddenly increased to 50% or more when the inundation heights were over 4 meters. Damage to houses is controlled directly by the hydraulic pressure dur to the water flow. The hydraulic pressure that acts upon a house is expressed as p∝hv2, where h is the inundation height above ground and υ the water velocity. The percentage of damage to houses reached 50% or more when the hydraulic pressure became 5～9m3/sec2. In many cases of tsunamis, the water velocity was 3～6m/sec at the mouth of a river, 1～3m/sec in the street area and 0.5～1m/sec near the foot of a hill. According to the report of the field investigation of the 1983 Nihonkai-Chubu tsunami at Hachimori, Akita Prefecture, most of the houses inundatated floor when the water level were 0.5～1.0 meters (above ground). The wooden houses were partially damaged when the inundation heights were about 1.5 meters and destroyed 2.0 meters or more, but the houses hardly washed away. In recent years, bolts have been set in the bottoms of wooden houses and powerful sea walls have been constructed, so there is a strong tendency for the number of houses washed away to decrease.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"128368","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hatori, Tokutaro"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000032918","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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"羽鳥, 徳太郎"}],"nameIdentifiers":[{"nameIdentifier":"128367","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":"ji0593005.pdf","filesize":[{"value":"382.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0593005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32918/files/ji0593005.pdf"},"version_id":"d5640cbd-ddff-405b-9fde-94e46186f5d9"}]},"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":"津波による家屋の破壊率","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"津波による家屋の破壊率","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4791","4792"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"32918","relation_version_is_last":true,"title":["津波による家屋の破壊率"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:49.133940+00:00"}
