This shows the D-statistic values of the two-sample K-S test for univariate sensitivity analysis of 2000 simulations, by percentile discretization. Legend: The critical value (Dα), related to an alpha value of 0.05, is marked with the dashed red line. The values below this level (precipitations) represent the non-significant samples from two simulations, whereas the remaining 1998, represented above the line, are considered to be at significance levels. Lines represent factors: 1geo = lithology (electric blue), 2cov = land use/vegetation coverage (orange), 3sei = seismicity (light gray), 4pre = precipitations (yellow), 5sta = soil stability (light blue), 6slo = slope (green), 7pop = population (dark blue), 8roa = road density (brown), 9bui = floor area (dark gray) and, 10gro = building footprint area (ochre). X-axis shows the multipliers of each factor’s coefficient and Y-axis shows the D/KS values
