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 >= 6 Lower, and 100% for events with M>7 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"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-30"},"publish_date":"2023-03-30","publish_status":"0","recid":"4729","relation_version_is_last":true,"title":["An Improved Rapid-Source Parameter Determination System (AQUA) for Giant Earthquakes"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-08T06:08:48.904654+00:00"}
