Abstract
Ground Motion Prediction Equations-GMPEs define the values of a ground motion parameter as a function of earthquake size and the distance in terms of both expected values and their dispersion. GMPEs are essential in probabilistic seismic hazard studies, which are a key step for the evaluation of seismic risk and loss estimation for a region. In the present study, six attenuation relationships were selected for shallow and three for intermediate depth earthquakes on the base of general criteria. The Nakamura method was applied to classify the soil conditions of Bulgarian stations. The LLH and LH approaches were used for quantifying the goodness of fit of these relations to a large dataset of ground motion data from Balkan region.
