Three kinds of seismic waves were recorded: (1) a teleseismic event occurred in the Kermadec Is. region, (2) local icequakes and (3) an unidentified event. The teleseismic waves show high signal-to-noise ratio in spite of the small magnitude of the event: this indicates that it is highly feasible to study not only the local shallow structure but also the deep structure of the earth by using teleseismic events. Frequency spectra of the waveforms show discordances along the observation line. The 2.0 Hz frequency component is very small in waveforms recorded by stations in the middle part of the observation line. On the other hand, the 1.5, 3.0 and 5.0 Hz frequency components are large in the records of these stations. These stations are located just above the valley topography of the interface between the ice sheet and the upper crust, which has been revealed by JARE-41 and JARE-43 seismological experiments.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00003140","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":"AA1130866X","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":"Geodynamics Research Center, Ehime University"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"},{"subitem_text_language":"en","subitem_text_value":"Department of Polar Science, The Graduate University for Advanced Studies"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2004-10-01"}],"displaytype":"detail","filename":"KJ00000712307.pdf","filesize":[{"value":"6.4 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000712307","url":"https://nipr.repo.nii.ac.jp/record/3140/files/KJ00000712307.pdf"},"version_id":"209711ad-9baf-4c71-87b7-4c49c13aabcb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Mizuho Plateau","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"seismic waveforms, stacking","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"frequency content","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"valley structure","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Features of seismic waves recorded by seismic exploration in 2002: Responses from valley structure of the bedrock beneath Mizuho Plateau","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Features of seismic waves recorded by seismic exploration in 2002: Responses from valley structure of the bedrock beneath Mizuho Plateau"}]},"item_type_id":"1","owner":"4","path":["442"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-10-01"},"publish_date":"2004-10-01","publish_status":"0","recid":"3140","relation_version_is_last":true,"title":["Features of seismic waves recorded by seismic exploration in 2002: Responses from valley structure of the bedrock beneath Mizuho Plateau"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:34:31.476961+00:00"}
