unilogo_bleu_72dpiWelcome on the website of the Risk Analysis group of the University of Lausanne. The group is the former Institute of Geomatics and Risk Analysis. Risk analysis is mainly oriented toward the study of natural and environmental risks and their perception in the society, particularly by studying the phenomena on earth’s surface and atmosphere that induce these risks. The research aims to quantify degradation, alteration and dismantling phenomena in the Alpine chain and other mountainous areas and to analyse the dangers and their impact on society. The teaching of the group turns towards the management of environmental risks and their societal impact.
