Description :
There are two types of processes active in the formation of a landscape at the same time: the endogenic (tectonic) and the exogenic (climate-driven) processes. These two types of processes may more or less balance each other, in which case the actual aspect of a landscape corresponds to the instantaneous dynamic equilibrium between them. Extremely small accidental pertubations can cause the system to become unstable, leading to rapid changes in the landscape which are experienced as hazard-events.
