We provide new field and laboratory evidence, including geochemical, geochronologic, and geological-morphological analysis, to reconstruct the evolution, triggering mechanisms, and physical parameters of these events.The lateral collapse (48~ka BP) was mainly predisposed by a tectonically westward-inclined substratum and rapid edifice growth rates (0.3–0.48 km3 ka-1). The resulting Planchón-Teno debris avalanche became valley-confined traveling at c. 260 km h-1 up to 95 km distance and forming an 8.6 ± 1.3 km3 deposit. The resulting 4.1 km wide amphitheater was later destroyed at c. 7 ka BP by the multiphase Valenzuela phreatomagmatic eruptions, forming a c. 2.5 km diameter caldera. The case of the Planchón volcano warns that rapidly growing mafic volcanoes imply a substantial catastrophic hazard increase for the surrounding areas.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Volcanica","subitem_publisher_language":"en"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.30909/vol.07.01.2149"}}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2610-3540","subitem_source_identifier_type":"EISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"José Antonio Naranjo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Jorge Romero","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Juan Pablo Contreras","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Yuji Orihashi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Kevin Scott","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Miguel Haller","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Hirochika Sumino","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_title":"Rapid growth and catastrophic destruction events of Planchón Volcano, Southern Andes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rapid growth and catastrophic destruction events of Planchón Volcano, Southern Andes","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"10","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-09-16"},"publish_date":"2024-09-16","publish_status":"0","recid":"6775","relation_version_is_last":true,"title":["Rapid growth and catastrophic destruction events of Planchón Volcano, Southern Andes"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-09-17T00:41:53.043216+00:00"}
