Simultaneous recordings of the change in the resistivity and the deformation of rock specimen make it clear that the rate of change in the resistivity of a pumice tuff specimen from Oya, Tochigi Prefecture, is of the same order as the strain and that the rate of a lapilli tuff specimen from Aburatsubo, Kanagawa Prefecture, is extremely larger, 102～103 times say, than the strain. The latter result supports Yokoyama's preliminary observation in situ. Yokoyama, who measured changes in the resistivity of the ground by tidal loading, reported an unusually large rate of change in the resistivity which approximately agrees with the rate as measured by the present laboratory experi- ment. Crude theories of electric conduction in such a material as tuff specimen are advanced. It is also pointed out that the electrical means as advanced here could possibly be applied to measuring extremely small changes in the earth's strain.","subitem_description_type":"Abstract"},{"subitem_description":"地殻に作用する歪力によつて,地殼を構成する物質の電気伝導度が変化するであろうという議論に対して一つの観測がある.それは横山泉により1951年から52年にわたり,神奈川県三浦市油壷附近でなされたものである.この観測によると,観測点近くの潮汐の変化により地殻の伸縮がおこり,この伸縮が10-6程度変るとき,地殼の電気伝導度,すなわち比抵抗が10-3の割合で変化することが観測された.つまり地殻の伸縮に対しての比抵抗変化率は102～103倍に達することとなる.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"131378","nameIdentifierScheme":"WEKO"}],"names":[{"name":"山崎, 良雄"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033615","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":"Earthquake Research Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"YAMAZAKI, Yoshio"}],"nameIdentifiers":[{"nameIdentifier":"131377","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":"ji0434009.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0434009.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33615/files/ji0434009.pdf"},"version_id":"58c7e03c-d0e6-4d2f-896f-e3a181209877"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"50.
