This method comprises the development of the Instantaneous Frequency Analysis which has a basis in the Maximum Entropy Spectral Analysis. The feasibility of this method is tested using synthetic seismograms. Particular attention is paid from the practical point of view to the optimum length of the linear prediction filter and the resolution to the interference of the fundamental mode and the higher mode. We compare this method with a conventional bandpass filtration technique using the same synthetic seismograms. Our results show that this method has the advantage of retrieving the higher mode group velocity even for shallow earthquakes.", "subitem_description_type": "Abstract"}, {"subitem_description": "\u8868\u9762\u6ce2\u306e\u5206\u6563\u3092\u7814\u7a76\u3059\u308b\u305f\u3081\u306e,\u9ad8\u7cbe\u5ea6\u306e\u7fa4\u901f\u5ea6\u63a8\u5b9a\u6cd5\u3092\u8003\u5bdf\u3057\u305f.\u3053\u306e\u65b9\u6cd5\u306f\u6700\u5927\u30a8\u30f3\u30c8\u30ed\u30d4\u30fc\u6cd5\u3092\u57fa\u790e\u3068\u3059\u308b,\u77ac\u9593\u5468\u6ce2\u6570\u89e3\u6790\u306b\u57fa\u3065\u3044\u3066\u3044\u308b.\u3053\u306e\u65b9\u6cd5\u306e\u6709\u52b9\u6027\u3092\u7406\u8ad6\u8a18\u8c61\u3092\u7528\u3044\u3066\u8abf\u3079,\u7279\u306b\u5b9f\u7528\u7684\u89b3\u70b9\u304b\u3089,\u4e88\u6e2c\u30d5\u30a3\u30eb\u30bf\u30fc\u306e\u6700\u9069\u306a\u9577\u3055\u53ca\u3073\u57fa\u672c\u30e2\u30fc\u30c9\u3068\u9ad8\u6b21\u30e2\u30fc\u30c9\u306e\u5e72\u6e09\u306b\u5bfe\u3059\u308b\u5206\u89e3\u80fd\u306b\u6ce8\u610f\u3092\u306f\u3089\u3063\u305f.\u3055\u3089\u306b\u30d0\u30bd\u30c9\u30d1\u30b9\u30d5\u30a3\u30eb\u30bf\u30fc\u306b\u3088\u308b\u65b9\u6cd5\u3068\u6bd4\u8f03\u3057\u305f.\u3053\u306e\u65b0\u3057\u3044\u65b9\u6cd5\u306f\u9707\u6e90\u306e\u6d45\u3044\u5730\u9707\u3067\u52b1\u8d77\u3055\u308c\u305f\u9ad8\u6b21\u30e2\u30fc\u30c9\u306e\u7fa4\u901f\u5ea6\u3092\u3082\u63a8\u5b9a\u3067\u304d\u308b\u70b9\u3067\u5f93\u6765\u306e\u65b9\u6cd5\u306b\u512a\u3063\u3066\u3044\u308b.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "128433", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u576a\u4e95, \u8aa0\u53f8"}]}, {"nameIdentifiers": [{"nameIdentifier": "128434", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u5927\u4e45\u4fdd, \u4fee\u5e73"}]}]}, "item_4_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.15083/0000032939", "subitem_identifier_reg_type": "JaLC"}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u5730\u9707\u7814\u7a76\u6240"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00162258", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00408972", "subitem_source_identifier_type": "ISSN"}]}, "item_4_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "453", "subitem_subject_scheme": "NDC"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "Earthquake Research Institute, University of Tokyo"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "Geophysical Institute, Faculty of Science, University of Tokyo"}, {"subitem_text_value": "Earthquake Research Institute"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tsuboi, Seiji"}], "nameIdentifiers": [{"nameIdentifier": "128431", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Okubo, Shuhei"}], "nameIdentifiers": [{"nameIdentifier": "128432", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-26"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "ji0583001.pdf", "filesize": [{"value": "534.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 534400.0, "url": {"label": "ji0583001.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/32939/files/ji0583001.pdf"}, "version_id": "4f780e8e-3d26-4ef8-b54d-02c09083404d"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "22.
