Although previous studies have primarily investigated rupture modes for entire ruptures, this study focused on the rupture mode during rupture propagation at each spatiotemporal point. Specifically, we introduced a metric to evaluate the rupture propagation direction and compared it with the slip direction. First, the validity of the metric was tested using a synthetic rupture. As a result, the estimated rupture mode for the circular-front rupture was mostly consistent with the assumed rupture mode, although a small slip around the reference location tended to cause a larger difference. We then applied this metric to the real earthquake and obtained various distributions of the spatiotemporal rupture modes. Through the stochastic analysis considering the uncertainty, we confirmed that rupture propagation exhibited a slight directional preference regarding the rupture mode except for the 2008 Iwate Miyagi Inland earthquake. For the 2008 Iwate Miyagi Inland earthquake, a strong barrier zone derived from a fault bending was likely to mitigate the rupture propagation, causing the biased rupture mode preference. This new metric for evaluating the rupture propagation direction can quantitatively represent the effects of rupture attenuation during source processes.", "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/s40623-025-02254-1"}}]}, "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": "Ritsuya Shibata", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Naofumi Aso", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Rupture mode preferences of crustal earthquakes in Japan", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Rupture mode preferences of crustal earthquakes in Japan", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "7", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/7291", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2025-08-18"}, "publish_date": "2025-08-18", "publish_status": "0", "recid": "7291", "relation": {}, "relation_version_is_last": true, "title": ["Rupture mode preferences of crustal earthquakes in Japan"], "weko_shared_id": -1}
