These observations were held at the same time in three places; which are surface ground, 30 feet and 68 feet deep underground respectively. The 68 feet deep underground level is exactly the boundary of alluvium and diluvium. The diluvium is made of compact materials and its bearing power is greater than 20 tons per square foot, while the alluvium is made of soft materials and its bearing power is less than 1 tons per square foot. Therefore, these observations have determine how 68 feet thick soft alluvial layer vibrates by seismic disturbances. The instruments were Ishimoto's seismic accelerometers. The authors have found that, in alluvial layer, there are numerous waves having about 0.2 sec. and 0.7 sec. periods; in diluvial formation, 0.25 sec. and 0.45 sec. respectively. In consequence of drawing the resonance curve for vibrations in the alluvium, the author are able to ascertain that 0.25 sec and 0.75 sec. are the proper periods of the alluvial layer. More-over, the acceleration in 68 feet deep underground was about 1/3 to 1/5 of the surface ground. These data will be available to engineering seismology and prevention for earthquake disaster.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"134687","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saita, Tokitaro"}]},{"nameIdentifiers":[{"nameIdentifier":"134688","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Masazi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000034806","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝国大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00029699","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, Tokyo Imperial University"}]},"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":"齊田, 時太郎"}],"nameIdentifiers":[{"nameIdentifier":"134685","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 正治"}],"nameIdentifiers":[{"nameIdentifier":"134686","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":"2017-06-27"}],"displaytype":"detail","filename":"ji0123015.pdf","filesize":[{"value":"3.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0123015.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/34806/files/ji0123015.pdf"},"version_id":"1a3df1e3-7fd3-43e4-aa5b-8f5efb4abb91"}]},"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":"丸の内に於て觀測された地上及地下の地震動に就て","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"丸の内に於て觀測された地上及地下の地震動に就て","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["5221","5222"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-06-06"},"publish_date":"2008-06-06","publish_status":"0","recid":"34806","relation_version_is_last":true,"title":["丸の内に於て觀測された地上及地下の地震動に就て"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:09:47.200615+00:00"}
