From this study, we propose that one of the possible reasons of pre-seismic change of the 2011 Tohoku Earthquake might have been smaller for its magnitude because its fault was composed smaller (M 7 class) asperities including the off Miyagi earthquakes as occurred in 1978 and 2005. We also suggest that the next megathrust earthquake along Nankai Trough in southwest Japan may have detectable pre-seismic change because it is composed of three large (M 8 class) asperities in Tokai, Tonankai and Nankai region. Our trial numerical simulation results by using vector-type super computer show that Dense Oceanfloor Network System for Earthquakes and Tsunamis (DONET) may be useful to detect the pre-seismic change of a possible M 9 class coupled megathrust earthquake composed of Tokai, Tonankai, Nankai and Hyuga-nada asperities. © Springer-Verlag Berlin Heidelberg 2013.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1007/978-3-642-32454-3-6"}}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Keisuke Ariyoshi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Toru Matsuzawa", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yasuo Yabe", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Naoyuki Kato", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ryota Hino", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Akira Hasegawa", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yoshiyuki Kaneda", "creatorNameLang": "en"}]}]}, "item_title": "Application of vector-type super computer to understanding giant earthquakes and aftershocks on subduction plate boundaries", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Application of vector-type super computer to understanding giant earthquakes and aftershocks on subduction plate boundaries", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4101", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4101", "relation": {}, "relation_version_is_last": true, "title": ["Application of vector-type super computer to understanding giant earthquakes and aftershocks on subduction plate boundaries"], "weko_shared_id": -1}
