Short summary
This paper presents simulations of all of the processes involved in a potential GLOF originating from Lake Palcacocha above the city of Huaraz, Peru. The chain of processes starting form an avalanche falling into the lake and leading to a possible GLOF are simulated and converted into flood intensity and hazard maps (based on an intensity-likelihood matrix) that may be useful for city planning and regulation. Erosion from the overtopping wave did not result in failure of the damming moraine.
