Geomorphology of the Ampato volcanic complex (Southern Peru)

Abstract

Few detailed geomorphological maps of the Central Andes are available despite the wide diversity of landforms. We present a 1:20,000 geomorphological map of the Ampato volcanic complex resulting from the interpretation of vertical aerial photographs (1955), MrSID resolution satellite image and oblique aerial photographs (1943). To classify the relief, Simonov [(1972). Regional geomorphological analysis [in Russian]. Moscow: Mosk. Gos. Univ] criteria are combined with the International Institute for Aerospace Survey and Earth Sciences (ITC) method. The use of both techniques allows us to represent 35 landform types distributed over an area of 930 km2 and to identify the geomorphic processes involved in their morphogenesis.
