### Soil Erosion Risk  
Regarding the soil erosion risk derived from the use of the RUSLE concerning the time periods before and after the fire incidents in the Attica region in 2021, the spatial distribution of soil loss is presented in the following Figures 5-8. Due to the assessed areas' heterogeneity of characteristics, the soil loss results in ton/ha/season were converted into a universal classification based on each area as presented in Table 5. More analytically, the 5 classes (from very low to very high erosion risk) were specified on an equal interval for each case estimated from the standard deviation average of soil loss before and after the fire events. In this way, a comparable classification, taking into consideration each area's \begin{table}

Table 4: Burned land cover of Attica region wildfires based on Corine Land Cover 2018 (% of the burned area total of each area per land cover category). soil loss results, was constructed which enables the identification of the change concerning erosion risk in pre-fire and post-fire results. Figure 5: Erosion Risk according to RUSLE soil loss for Schinos burned area: (**a**) before the fire; (**b**) after the fire. The erosion risk as classified is presented including the percentage of the burned area total of each area per class. Figure 6: Erosion Risk according to RUSLE soil loss for Varympompi burned area: (**a**) before the fire; (**b**) after the fire. The erosion risk as classified is presented including the percentage of the burned area total of each area per class. Figure 7: Erosion risk according to RUSLE soil loss for Lavreotiki burned area: (**a**) before the fire; (**b**) after the fire. The erosion risk as classified is presented including the percentage of the burned area total of each area per class. Soil loss results, in general, show a clear differentiation between the pre-fire and post-fire states in all four areas. More specifically, the pre-fire state is characterized by very low soil erosion risk, which is predominant in all cases. Regarding the post-fire soil erosion risk, it was clearly increased in the four areas of interest. Very low soil erosion risk was reduced to 45.76% whereas the low and moderate soil erosion risk constitutes a combined 40.12% of the burned areas. Moreover, the rest areas are characterized by high and very high soil erosion risk values of almost 7% each.
