predictions are tried by extracting seismic electric signals (SES), which are sometimes contained in telluric current data (TCD). TCD observed in Japan is also containing strong train noise. To separate train noise from TCD, independent component analysis (ICA) has been applied for TCD. The result shows high effect of ICA to separate train noise. However, SES have not been detected in the experiments. In this paper, we approach auto-detection of SES from data, which are separated TCD by ICA. As an experiment of our method, we apply the method to TCD, which may contain SES of The Mid Niigata Prefecture Earthquake in 2004. We also investigate correlation between the result of the experiments and information of earthquake occurrence.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"31","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌数理モデル化と応用（TOM）"}],"bibliographicPageStart":"22","bibliographicIssueDates":{"bibliographicIssueDate":"2010-03-17","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"3"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":68411,"links":{}}
