NEVADOS DE CHILLÁN A continuación se presentan las variaciones areales de los glaciares ubicados en el complejo volcánico Nevados de Chillán (36° 51’ 48” S , 71° 22’ 36” O) entre el año 1975 y el 2011. La información de las variaciones de área fue obtenida mediante técnicas de percepción remota sobre imágenes satelitales LANDSAT MSS  y del sensor ASTER de satélite TERRA. Figura 1.1 “Variaciones de área Nevados de Chillán”     Además del constante estudio de las ...

Glaciers and volcanoes studies in Southern Chile
Volcanological studies in Southern Chile

Volcanological studies in Southern Chile have mainly focused on geological, geochemical and flow dynamics characteristics of the main active volcanoes, their products and recent eruptions, including their eruptive histories, effusion rates, pyroclastic flows, lava flow dynamics, mud flow deposits and associated volcanic hazards (e. g. Lara, 2004; Clavero and Moreno, 2004; Moreno and Clavero, 2006; Moreno, 1993 and 2000;Castruccio et al., 2006). However, most of human volcanic-related casualties in the region...

Climate changes in the region
Glaciers in Southern Chile and Argentina

Glaciers in Southern Chile and Argentina (36 to 46°S) have been retreating and shrinking during recent decades, presumably in response to a reduction in precipitation and upper atmosphere warming observed during the second half of the XXth century (Rivera et al., 2002; Aniya et al., 1997; Rignot et al., 2003; Carrasco et al., 2005; Villalba, 1990 and 1994; Villalba et al., 1990; Rabassa et al., 1978). Very few glacier exceptions to this trend have been observed, especially among tidewater and some freshwater Patagon...
