The icequakes are roughly classified into two groups from their waveforms : a high frequency type and a low frequency type. Icequakes of the high frequency type occurred about 1.8 times more than those of the low frequency type during the 24 months from February 1990 to January 1992. In the monthly numbers, there are some swarms, however, in daily numbers, only one icequake swarm of low frequency type was observed. A big tremor was also recorded during the swarm. All icequakes and tremors appear to originate in the continental ice sheet. Seismic observations at Syowa Station seem to be useful to monitor ice sheet movement.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00002713","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA1072335X","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, the University of Tokyo"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1993-09-01"}],"displaytype":"detail","filename":"KJ00002368343.pdf","filesize":[{"value":"620.3 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002368343","url":"https://nipr.repo.nii.ac.jp/record/2713/files/KJ00002368343.pdf"},"version_id":"d33b13dd-508e-41e2-bf6d-88a2e51170e8"}]},"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":"ICEQUAKES RECORDED AT SYOWA STATION, ANTARCTICA","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ICEQUAKES RECORDED AT SYOWA STATION, ANTARCTICA"}]},"item_type_id":"1","owner":"4","path":["420"],"pubdate":{"attribute_name":"公開日","attribute_value":"1993-09-01"},"publish_date":"1993-09-01","publish_status":"0","recid":"2713","relation_version_is_last":true,"title":["ICEQUAKES RECORDED AT SYOWA STATION, ANTARCTICA"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:43:41.581187+00:00"}
