  abstract = {{T}he first step in the estimation of probabilistic seismic hazard in a region commonly consists of the definition and characterization of the relevant seismic sources. {B}ecause in low-seismicity regions seismicity is often rather diffuse and faults are difficult to identify, large areal source zones are mostly used. {T}he corresponding hypothesis is that seismicity is uniformly distributed inside each areal seismic source zone. {I}n this study, the impact of this hypothesis on the probabilistic hazard estimation is quantified through the generation of synthetic spatial seismicity distributions. {F}ractal seismicity distributions are generated inside a given source zone and probabilistic hazard is computed for a set of sites located inside this zone. {I}n our study, the impact of the spatial seismicity distribution is defined as the deviation from the hazard value obtained for a spatially uniform seismicity distribution. {F}rom the generation of a large number of synthetic distributions, the correlation between the fractal dimension {D} and the impact is derived. {T}he results show that the assumption of spatially uniform seismicity tends to bias the hazard to higher values. {T}he correlation can be used to determine the systematic biases and uncertainties for hazard estimations in real cases, where the fractal dimension has been determined. {W}e apply the technique in {G}ermany ({C}ologne area) and in {F}rance ({A}lps).},
