Dendroclimatological reconstructions in South America: A review
(CIENCIAS, 2009)Recent years have seen a consolidation and expansion of tree-ring sample collection across South America. Most collections are concentrated in the temperate forests along the eastern and western slopes of the Southern Andes ... -
Eruptive parameters and dynamics of the April 2015 sub-Plinian eruptions of Calbuco volcano (southern Chile)
(CIENCIAS, 2016)We conducted geological and petrological analyses of the tephra fallout and pyroclastic density current (PDC) products of the 22-23 April 2015 Calbuco eruptions. The eruptive cycle consisted of two sub-Plinian phases that ... -

Explosive style, magma degassing and evolution in the Chaimilla eruption, Villarrica volcano, Southern Andes
(CIENCIAS, 2015)Villarrica (Chile) is a basaltic stratovolcano, currently in an open-conduit condition. It now has relatively frequent Strombolian and effusive eruptions, but it had large explosive eruptions in prehistoric times. Among ... -
Isolation and characterization of an Antarctic Flavobacterium strain with agarase and alginate lyase activities
(CIENCIAS, 2016)Several bacteria that are associated with macroalgae can use phycocolloids as a carbon source. Strain INACH002, isolated from decomposing Porphyra (Rhodophyta), in King George Island, Antarctica, was screened and characterized ... -
Potential use of organic- and hard-rock mine wastes on aided phytostabilization of large-scale mine tailings under semiarid mediterranean climatic conditions: Short-Term field study
(Facultad de Ciencias, 2012)The study evaluated the efficacy of organic- and hard-rock mine waste type materials on aided phytostabilization of Cu mine tailings under semiarid Mediterranean conditions in order to promote integrated waste management ... -
Recent changes in total ice volume on Volcan Villarrica, Southern Chile
(CIENCIAS, 2015)Results obtained by the first intensive airborne surveys carried out at Volcan Villarrica (39 degrees S) in Southern Chile, are presented. These campaigns included the use of a scanner laser system, for detecting the glacier ... -
The origin and emplacement of Domo Tinto, Guallatiri volcano, Northern Chile.
(CIENCIAS, 2014)El volcán Guallatiri (18°25'S, 69°05'W) es un edificio volcánico ubicado en el Altiplano del norte de Chile, cercano a la frontera con Bolivia. Este volcán, construido en el Pleistoceno-Holoceno en el extremo sur de la ... -
Thermal remote sensing of ice-debris landforms using ASTER: an example from the Chilean Andes
(CIENCIAS, 2012)Remote sensors face challenges in characterizing mountain permafrost and ground thermal conditions or mapping rock glaciers and debris-covered glaciers. We explore the potential of thermal imaging and in particular thermal ...
