Many volcanic eruptions have occurred during the Quaternary in the Andes and particularly in the area of northern Argentina and Chile with the generation of environmental impacts of diverse magnitude. The average rate is about one eruption per year in the Southern Cone. QUECA Project is addressed to the analysis of the environmental impact of Quaternary eruptions of the central Andes, with particular consideration of the Holocene events by the involvement of men, to extract patterns to model the prediction and prevention of the effects of future eruptions in environment, focusing on its geographic and temporal scope. Project is focused in the most factible scenarios, including those that have a local impact, effusive (lava fields that can affect human sttlemensts and agricultural fields and water courses, by deviation or interruption), and regional impacts due to explosive eruptions (ash deposits).
The objectives of Project QUECA are:
- Analysis of the extent and temporal persistence of the geochemical impact of high explosive case study Quaternary eruptions, emphasizing the Holocene ones by the involvement of men, to model the prediction and prevention of the effects of future eruptions in the environment of the Andean region.
- Development and validation of experiemental methods to simulate over time the behaviour of geochemical inputs generated by the ashes when interact with water.
- Calibration and validation of hyperspectral remote sensing imagery for early detection of the composition and extent of erupted material.
