Peak frequency of the velocity spectrum is used instead of corner frequency. Brune model is used. The stress drop of the aftershock is estimated as about 1~30 bars. During the chain breaks which frequently appear immediately after the main shock, the stress level locally decreases to appoximately 1/20. High frequency component predominate in the foreshock which occurred about 8 days before the main shock. This shows that the stress level before the main shock was about 3~100 times higher than that of the aftershocks. The spectral analysis is very effective in clarifying the process of earthquake genesis.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"\u5185\u5bb9\u8a18\u8ff0","attribute_value_mlt":[{"subitem_description":"1974\u5e74\u4f0a\u8c46\u534a\u5cf6\u6c96\u5730\u9707\u8abf\u67fb\u6982\u5831","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"\u8457\u8005\u5225\u540d","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71062","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nagumo, Shozaburo"}]},{"nameIdentifiers":[{"nameIdentifier":"71063","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ouchi, Toru"}]}]},"item_4_identifier_registration":{"attribute_name":"ID\u767b\u9332","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032034","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":"AN10165194","subitem_source_identifier_type":"NCID"}]},"item_4_subject_15":{"attribute_name":"\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5","attribute_value_mlt":[{"subitem_subject":"051.1","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_4":{"attribute_name":"\u8457\u8005\u6240\u5c5e","attribute_value_mlt":[{"subitem_text_value":"\u5730\u9707\u7814\u7a76\u6240"}]},"item_creator":{"attribute_name":"\u8457\u8005","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"\u5357\u96f2, \u662d\u4e09\u90ce"}],"nameIdentifiers":[{"nameIdentifier":"71060","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"\u5927\u5185, \u5fb9"}],"nameIdentifiers":[{"nameIdentifier":"71061","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":"2017-06-12"}],"displaytype":"detail","filename":"jis0140012.pdf","filesize":[{"value":"517.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jis0140012.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32043/files/jis0140012.pdf"},"version_id":"abe33766-061a-4cc1-a489-ace60de63d70"}]},"item_language":{"attribute_name":"\u8a00\u8a9e","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"1974\u5e74\u4f0a\u8c46\u534a\u5cf6\u6c96\u5730\u9707\u3001\u30b9\u30da\u30af\u30c8\u30eb\u89e3\u6790\u306b\u3088\u308b\u524d\u9707\u53ca\u3073\u4f59\u9707\u306e\u5fdc\u529b\u72b6\u614b\u306e\u63a8\u5b9a","item_titles":{"attribute_name":"\u30bf\u30a4\u30c8\u30eb","attribute_value_mlt":[{"subitem_title":"1974\u5e74\u4f0a\u8c46\u534a\u5cf6\u6c96\u5730\u9707\u3001\u30b9\u30da\u30af\u30c8\u30eb\u89e3\u6790\u306b\u3088\u308b\u524d\u9707\u53ca\u3073\u4f59\u9707\u306e\u5fdc\u529b\u72b6\u614b\u306e\u63a8\u5b9a"}]},"item_type_id":"4","owner":"1","path":["80/4411/4412","9/504/4413/4414"],"pubdate":{"attribute_name":"\u516c\u958b\u65e5","attribute_value":"2010-12-22"},"publish_date":"2010-12-22","publish_status":"0","recid":"32043","relation_version_is_last":true,"title":["1974\u5e74\u4f0a\u8c46\u534a\u5cf6\u6c96\u5730\u9707\u3001\u30b9\u30da\u30af\u30c8\u30eb\u89e3\u6790\u306b\u3088\u308b\u524d\u9707\u53ca\u3073\u4f59\u9707\u306e\u5fdc\u529b\u72b6\u614b\u306e\u63a8\u5b9a"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2021-03-01T13:34:20.958662+00:00"}
