Probabilistic Volcanic Hazard Assessment of the 22.5–28°S Segment of the Central Volcanic Zone of the Andes

Abstract: Evaluation of volcanic hazards typically focusses on single eruptive centres or spatially restricted areas, such as volcanic fields. Expanding hazard assessments across wide regions (e.g., large sections of a continental margin) has rarely been attempted, due to the complexity of integrating temporal and spatial variability in tectonic and magmatic processes. In this study, we investigate new approaches to quantify the hazards of such long-term active and complex settings, using the example of the 22.5–28°S se… Show more

“…The attempt of Zorn et al (2022) to find potentially tsunamigenic volcanoes in Indonesia, by creating a ranking system based on globally available datasets, for example, can potentially be improved with additional information below the sea level. With an extensive database, a probabilistic volcanic hazard approach, similar to the methods of Bertin et al (2022) will become possible.…”

“…A recent highlight for me has been to rekindle my interest in the Central Andes by co-supervising a Chilean PhD student, Daniel Bertin, who developed a comprehensive volcanic database and volcanic hazard assessment for the region (Bertin et al, 2022;Bertin et al, 2023). It was particularly rewarding to co-supervise Daniel with Shan de Silva, my former adviser.…”

“…Unlike the Southern Volcanic Zone (SVZ), which has recorded dozens of historic eruptions from several volcanoes (Dzierma and Wehrmann, 2012), in the southernmost sector of the CVZ, only the Lascar volcano records confirmed historical explosive eruptions (Gardeweg et al, 1998). However, it should be considered that most of the volcanoes in this region have little or no information about their eruptive history, especially for the Holocene (Bertin et al, 2022). In contrast, Holocene stratigraphic record along the intermontane valleys located at the eastern foothills of the Andes (200-300 km from the arc, Fig.…”

“…1a) of the Andes (14-28 • S) has been characterized by a prolific arc volcanism featuring hundreds of stratovolcanoes, collapse calderas, dome complexes, and mafic monogenetic centers (e.g., Trumbull et al, 2006;Kay y Coira 2009;Guzmán et al, 2014;Petrinovic et al, 2017;Wörner et al, 2018;Bertin et al, 2022Bertin et al, , 2023Báez et al, 2023). In the southernmost sector of the CVZ (23-28 • S), there are an estimated 30 to 40 volcanoes that are considered as potentially active (de Silva y Francis, 1991;Lara et al, 2011;Amigo et al, 2012;Elissondo et al, 2017;Aguilera et al, 2022;Bertin et al, 2022). These active arc and rear-arc volcanoes lay along the Chile-Argentina border, and most of them are far from populated urban centers.…”
