The tremors were classified into three types by spectral and waveform features. Type A events have long durations, typically several hours to days, with high amplitudes of spectra over 1–8 Hz. They occur dominantly in austral summers. Type B events have characteristically irregular variations in discrete dominant frequencies in spectra. Type C events are harmonic tremors with discrete dominant frequencies in spectra that vary regularly with time. Type B and C events show similar seasonal variations: they are numerous around April and less so in austral winter. Comparison of spectra between seismic waves and infrasound, together with satellite images, suggests that type A events originated from storm-induced swells near off-LHB. Source locations of type C events and satellite images suggest that type C events are likely to result from the collision/crevassing of ice blocks in fast-sea-ice in LHB. Similar seasonal variations of type B and C events imply that these two events have similar origins.","subitem_description_type":"Abstract"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1016/j.polar.2018.11.010"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.polar.2018.11.010","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18739652","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tanaka, Yuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hiramatsu, Yoshihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishihara, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanao, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cryosphere","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Fast-sea-ice","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Harmonic tremor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Microbaroms","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MODIS","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Characteristics of non-tectonic tremors around the Lützow-Holm Bay, East Antarctica, during 2013–2015","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Characteristics of non-tectonic tremors around the Lützow-Holm Bay, East Antarctica, during 2013–2015"},{"subitem_title":"Characteristics of non-tectonic tremors around the Lützow-Holm Bay, East Antarctica, during 2013–2015","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"25","path":["1932"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-31"},"publish_date":"2019-03-31","publish_status":"0","recid":"15603","relation_version_is_last":true,"title":["Characteristics of non-tectonic tremors around the Lützow-Holm Bay, East Antarctica, during 2013–2015"],"weko_creator_id":"25","weko_shared_id":-1},"updated":"2023-07-25T13:27:10.129991+00:00"}
