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\u0027ichi 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"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5886", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5886", "relation": {}, "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_shared_id": -1}
