We have imaged the rupture process of the M-w 7.8 earthquake by back-projection of waveform data from the Metropolitan Seismic Observation network (MeSO-net). Original acceleration seismograms were integrated. They were then band-pass filtered in the frequency range of 0.1-1.0 Hz. We assumed a fault plane on the plate boundary with a dimension of 115 km x 175 km, and this was divided into 112 subfaults. Travel times from each of the subfaults to observation sites were calculated by using a 3-D velocity structure model. Applying the restrictions that the rupture velocity is smaller than 4 km/s and the rupture duration on each subfault is less than 25 s, we obtained a rupture propagation image by projecting the power of the stacked waveforms. Propagation of the rupture toward north and east was suppressed by the existence of those areas that had radiated a large seismic energy at the main shock occurrence, or at the occurrence of the M 7.0 earthquake in 2008. The westward propagation of the rupture stopped at the area where the Philippine Sea plate lies over the Pacific plate.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"TERRA SCIENTIFIC PUBL CO","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.5047/eps.2013.01.003"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1343-8832","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ryou Honda","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Yohei Yukutake","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hiroshi Ito","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Masatake Harada","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Tamotsu Aketagawa","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Akio Yoshida","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Shin'ichi Sakai","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Shigeki Nakagawa","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Naoshi Hirata","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kazushige Obara","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Makoto Matsubara","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hisanori Kimura","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"Rupture process of the largest aftershock of the M 9 Tohoku-oki earthquake obtained from a back-projection approach using the MeSO-net data","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rupture process of the largest aftershock of the M 9 Tohoku-oki earthquake obtained from a back-projection approach using the MeSO-net data","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"5886","relation_version_is_last":true,"title":["Rupture process of the largest aftershock of the M 9 Tohoku-oki earthquake obtained from a back-projection approach using the MeSO-net data"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T09:32:10.488457+00:00"}
