Having the ability to travel considerable distances from their source, Glacial Lake
Outburst Floods (GLOFs) represent one of the most important glacial hazards. In line with observations in other parts of the world, the frequency of GLOF events in Chile has increased in recent decades highlighting the need to quantify the flood risk posed to downstream areas. This poster presents the work of the ‘Glacial Hazards in Chile’ project which aims to (1) better understand the processes that govern the development of GLOFs in Chile, (2) estimate the
socio-economic effects of GLOFs in Chile, and (3) provide a GLOF risk assessment framework that can be applied to Chile and other lower income countries globally. As an initial step towards the completion of these aims, we have recently compiled the first glacial lake inventory for the central and Patagonian Andes, which details the temporal development of glacial lakes
in this region over the past three decades. This analysis was used to identify two lakes of interest that were visited during a fieldwork expedition in February 2017. The first of these, Lago Chileno in Patagonia, has recently produced a large GLOF causing significant damage to the downstream floodplain, whilst the second was identified as one of the fastest growing lakes in the central Andes. Both these lakes were surveyed using drone acquired aerial imagery and a custom-built bathymetry boat, data from which will help to improve our
understanding of the physical processes associated with glacial lake development and failure within the Chilean Andes
