Late Holocene history of Chaitén Volcano: New evidence for a 17th century eruption

Abstract: ABSTRACT. Prior to May 2008, it was thought that the last eruption of Chaitén Volcano occurred more than 5,000 years ago, a rather long quiescent period for a volcano in such an active arc segment. However, increasingly more Holocene eruptions are being identified. This article presents both geological and historical evidence for late Holocene eruptive activity in the 17 th century (AD 1625-1658), which included an explosive rhyolitic eruption that produced pumice ash fallout east of the volcano and caused cha… Show more

“…Hudson in 1991, Chait en in 2008, Puyehue Cord on-Caulle in 2011, Calbuco in 2015 have also served as a driver for renewed field investigations so that eruptive histories and potential hazards posed to adjacent and downwind communities can be better clarified (i.e. Lara, 2009;Wilson et al, 2011aWilson et al, , 2011bAmigo et al, 2013;Lara et al, 2013;Watt et al, 2013;Alloway et al, 2015Alloway et al, , 2017.…”

“…These recent events have raised considerable awareness in the local inhabitants, Chilean and Argentinian authorities and the scientific community about the recurrence of rhyolitic eruptions (VC and PCC), a potentially devastating type of explosive volcanism, from putative dormant or inactive centers as well as their broad impacts on human activities and terrestrial ecosystems. Recent studies have detected a more active explosive eruptive history at VC than originally thought, raising the estimate of 1 or 2 events since 10,500 yr BP (Naranjo and Stern, 2004) to 6 events since 9750 cal yrs BP Lara et al, 2013;Watt et al, 2013). Previous estimates were based on whole-rock geochemistry from the soilforming environments, constrained by limited radiocarbon dating of key horizons.…”

“…(arriba, izquierda) daño en el sector norte de la ciudad, donde un cauce secundario y más directo hacia el mar se estableció temporalmente (www.elrepuertero.cl). Existe evidencia geológica (Lara et al 2013) de que este sector constituía un curso fluvial previo al emplazamiento de la población. (arriba, derecha) daño en el sector sur de la localidad, que corresponde al área de mayor acumulación de sedimentos en la planicie aluvial del río Blanco (www.taringa.net).…”

“…Mapa de Peligros Volcánicos del entorno de la ciudad de Chaitén (tomado de Moreno & Lara, 2008). Este mapa fue elaborado durante la crisis de mayo-junio 2008 y los escenarios eruptivos representados fueron ratificados posteriormente en estudios de mayor detalle (e.g., Major et al 2013;Lara et al 2013).…”
