Three different rainy seasons with different rainfall patterns were analysed. The analysis aims to understand the influence of the antecedent rainfall on the wetting front, the pore-water pressures and the factor of safety. The analysis was carried out in the context of a Master project of the first author at the Laboratory for Soil Mechanics of EPFL.ground water seepageunsaturated volcanic ashrainfall-induced landslideinfinity slope analysistext::conference output::conference proceedings::conference paper
