Journal of South American Earth Sciences, 2019 On May 2, 2008, the Chaiten volcano, located in Chilean Patagonia, thought to be inactive for almost 10,000 years, erupted, emitting pyroclastic materials (ash and pumice) of rhyolitic composition.

Vegetation dieback as a proxy for temperature within a wet pyroclastic density current: A novel experiment and observations from the 6th of August 2012 Tongariro eruption [PDF]
, 2014 The 6th of August 2012 eruption of Te Maari (Mt Tongariro, New Zealand) generated wet pyroclastic density currents (PDCs) which caused widespread dieback of vegetation (singed, brown foliage) in their path.

Early vegetation recovery after the 2008-2009 explosive eruption of the Chaitén Volcano
bioRxiv, 2019 In May 2008, Chaiten volcano entered in eruptive process, one of the world largest in the last time decades. The catastrophic event left different type of disturbance and caused diverse environmental damage.

Prediction of Lahar flow dynamics using simulation modeling [PDF]
Известия Саратовского университета. Новая серия: Серия Науки о ЗемлеThe study presents the testing and results of simulation modeling of surface flows caused by the results of volcanic activity. An analysis of various rheological models was carried out, with a justification for the effectiveness of the Herschel-Bulkley ...

Co-eruptive deformation and dome growth during the 2008-2009 Chaitén eruption, Southern Andes
Andean Geology, 2013 GPS data from stations around the Chaitén Volcano show a co-eruptive pattern of inflation and deflation that correlates well with the estimated effusion rate during the 2008-2009 eruption. Axisymmetric radial deflation is coeval with periods of fast dome

Latin American Journal of Sedimentology and Basin Analysis, 2022 Typically, the stratigraphic record of syn-eruptive fluvial successions is a pyroclastic-rich one. It includes an alternation of braided channel deposits and sheet-like floodplain strata, in which the occurrence of paleosols with in situ trees and ...

Storage and eruption of near-liquidus rhyolite magma at Cordón Caulle, Chile [PDF]
, 2013 International audienceThe last three eruptions at the Cordón Caulle volcanic complex, Chile, have been strikingly similar in that they have started with relatively short pre-eruptive warning and produced chemically homogeneous rhyolite to rhyodacite ...
