Abstract

ln the course of the Mountain Hazards Mapping Project in the Central Andes from Chile (Project FONDECYT Nº 482-91) natural hazards were assessed and mapped in the Aconcagua Bassin Test area of the high Andes (2.500 to 4.000 m.). Various geomorphic hazard processes (avalanches, rockfalls, landslide hazards, water activity) were mapped on the scale 1:50.000 with a simplified legend. The mountainous area seems to be relatively stable and the rock substratum (mainly granitic) is resistant to weathering. The greatest hazards are avalanches and landslides, which have a long recurrence interval and are difficult to predict, although their source areas can be identified.
