We discuss the applicability of dating methods for determining landslide chronologies in relation to the type of samples and the stratigraphic setting of sampling location. Case studies are carried out with fossil wood samples buried in the deposits of large-scale landslides in two areas of the Japanese Alps region in historic times ; Dondokosawa rock avalanche (DRA) and Ohtsukigawa debris avalanche (ODA). Ages are determined by accelerator mass spectrometry radiocarbon dating and dendrochronological analysis using the oxygen isotope composition of tree ring cellulose. We report seven radiocarbon ages and five dendrochronology data for the wood samples taken from outcrops and excavated trenches in the lacustrine sediments of dammed lakes formed by DRA, and two radiocarbon ages and two dendrochronology data for wood samples of ODA. Two sets of data for DRA are crosschecked independently to ensure the accuracy of results. Most of ages in the DRA area are concordant with the period of AD 887 Ninna (Goki-Shichido) mega-earthquake as proposed in previous studies. In the ODA area, ages are not concentrated in a specific period. When the preservation condition of buried wood trunks is good enough to date the exact or approximate tree-death years dendrochronologically, it is possible to estimate landslide occurrence periods in further detail by comparing the landslide chronology with historical records of heavy rainfall and large earthquakes.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "公益社団法人 砂防学会", "subitem_publisher_language": "ja"}, {"subitem_publisher": "Japan Society of Erosion Control Engineering", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.11475/sabo.73.5_3"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2187-4654", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "山田隆二", "creatorNameLang": "ja"}, {"creatorName": "YAMADA Ryuji", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "木村誇", "creatorNameLang": "ja"}, {"creatorName": "KIMURA Takashi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "苅谷愛彦", "creatorNameLang": "ja"}, {"creatorName": "KARIYA Yoshihiko", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "佐野雅規", "creatorNameLang": "ja"}, {"creatorName": "SANO Masaki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "對馬あかね", "creatorNameLang": "ja"}, {"creatorName": "TSUSHIMA Akane", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "李貞", "creatorNameLang": "ja"}, {"creatorName": "LI Zhen", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "中塚武", "creatorNameLang": "ja"}, {"creatorName": "NAKATSUKA Takeshi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "國分(齋藤)陽子", "creatorNameLang": "ja"}, {"creatorName": "SAITO-KOKUBU Yoko", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "井上公夫", "creatorNameLang": "ja"}, {"creatorName": "INOUE Kimio", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_title": "大規模土砂移動発生履歴の高精度復元に向けた埋没樹木の年代測定―歴史時代に中部山岳地域で発生した事例―", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "大規模土砂移動発生履歴の高精度復元に向けた埋没樹木の年代測定―歴史時代に中部山岳地域で発生した事例―", "subitem_title_language": "ja"}, {"subitem_title": "Dating of buried wood logs and fragments for high resolution reconstruction of landslide histories : Case studies in the Japanese Alps region in the historical times", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/3033", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "3033", "relation": {}, "relation_version_is_last": true, "title": ["大規模土砂移動発生履歴の高精度復元に向けた埋没樹木の年代測定―歴史時代に中部山岳地域で発生した事例―"], "weko_shared_id": -1}
