In recent years, computer development has advanced probabilistic tsunami hazard assessments (PTHAs), where hazard curves show the exceedance probability of the maximum tsunami height. However, owing to the lack of historical and geological tsunami records, this method is generally insufficient for validating the estimated hazard curves. The eastern coast of Shikoku in the Nankai subduction zone, Japan, is suitable for validation because tsunami records from historical Nankai Trough earthquakes are available. This study evaluated PTHAs by comparing the tsunami hazard curves and exceedance frequencies of historical Nankai Trough tsunamis. We considered 3480 earthquake scenarios representing the rupture patterns of past Nankai earthquakes and calculated all tsunamis. The probability of earthquake occurrence was based on the Gutenberg?Richter law. We considered uncertainty in tsunami calculations with astronomical tide variations. The estimated tsunami hazard curves are consistent with the exceedance frequencies obtained from historical tsunamis. In addition, sensitivity tests indicate the significance of the earthquake slip heterogeneity and tsunami defense facilities in PTHAs. We also extended the PTHAs to tsunami inundation maps in high resolution and proposed an effective new method for reducing the tsunami computation load.\n\n Graphical Abstract", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Springer Science and Business Media LLC", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1186/s40623-022-01715-1"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1880-5981", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Toshitaka Baba", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Masato Kamiya", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Naoki Tanaka", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Yusuke Sumida", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Ryoichi Yamanaka", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Kojiro Watanabe", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hiroyuki Fujiwara", "creatorNameLang": "en"}]}]}, "item_title": "Probabilistic tsunami hazard assessment based on the Gutenberg?Richter law in eastern Shikoku, Nankai subduction zone, Japan", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Probabilistic tsunami hazard assessment based on the Gutenberg?Richter law in eastern Shikoku, Nankai subduction zone, Japan", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "7", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/6403", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-09-20"}, "publish_date": "2023-09-20", "publish_status": "0", "recid": "6403", "relation": {}, "relation_version_is_last": true, "title": ["Probabilistic tsunami hazard assessment based on the Gutenberg?Richter law in eastern Shikoku, Nankai subduction zone, Japan"], "weko_shared_id": -1}
