Here, we address these problems by incorporating strong-motion seismic data and changing processing parameters accordingly, which extends the upper limit of applicable magnitudes to M9. In a simulated process, this earthquake is properly determined as thrust faulting with M8.6 offshore northeast Japan within 431 s of the first phase arrival. We also evaluate its performance. After improvements, four recent large earthquakes (M7.0-7.9) were properly processed in real time. The successful determination ratio is 100% for events with Japanese seismic intensity \u003e= 6 Lower, and 100% for events with M\u003e7 except nearly simultaneous events. Source parameters with and without fixed horizontal locations are provided within 100-250 and 100-600 s of the first P arrival, respectively. This system is valuable for disaster mitigation because it rapidly provides information for use in tsunami warning and early damage assessment.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Institute of Electrical and Electronics Engineers (IEEE)", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1109/jsyst.2020.2983430"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2373-7816", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hisanori Kimura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takeshi Kimura", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Youichi Asano", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Takashi Kunugi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Shin Aoi", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "An Improved Rapid-Source Parameter Determination System (AQUA) for Giant Earthquakes", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "An Improved Rapid-Source Parameter Determination System (AQUA) for Giant Earthquakes", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4729", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "4729", "relation": {}, "relation_version_is_last": true, "title": ["An Improved Rapid-Source Parameter Determination System (AQUA) for Giant Earthquakes"], "weko_shared_id": -1}
