The former was installed in a waterproof, steel-cased hole 196cm deep and 144mm in diameter. The observations began in April 1981. This paper discusses the borehole tiltmeter data from April to December. The signals were recorded on a 12-channel chart recorder in the data processing hut, 150m north from the observation hole. The maximum tilt fluctuation during nine months was 17μrad in the X-component (E-W) and 24μrad in the Y-component (N-S). As the data seem to be seriously affected by underground temperature variations, the observed data were corrected for temperature assuming a linear relation between the ground tilt and the underground temperature. The corrected records showed a trend of upward tilt on the west and north sides throughout the observation period. The cumulative change of ground tilt during nine months of observation was -1.5μrad in the X-component and 6μrad in the Y-component. These observations demonstrate that a true ground tilt can be detected by the borehole tiltmeter.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA00733561","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Science, Chiba University"},{"subitem_text_language":"en","subitem_text_value":"Regional Observation Center for Earthquake Prediction, Faculty of Science, Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1983-10-01"}],"displaytype":"detail","filename":"KJ00000012091.pdf","filesize":[{"value":"760.6 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000012091","url":"https://nipr.repo.nii.ac.jp/record/1458/files/KJ00000012091.pdf"},"version_id":"758fb5e1-8cd6-4e1f-98d9-c26e27e704bd"}]},"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":"Ground tilt observations at Syowa Station, Antarctica.
