Abstract

Tension (or intensity) of geomorphological system is its inclination to be in the state of instability, out of balance. It corresponds to high probability of catastrophic processes realization. The intensity of geomorphic processes in the Andes is determined by tectonic activity, volcanism, deeply dissected topography, high precipitation, seismicity, significant human impact. Most extensive geomorphologic disasters of the region are usually due to the superposition and interaction of the number of extreme processes.

Keywords

Andes, geomorphological processes, intension, risk, hazard, tectonics, volcanism, seismicity, relief dissection, precipitation, anthropogenic stress, superposition of processes
