Besides event and station metadata, ground motion parameters, computed in a homogeneous manner, were assembled: PGA, PGV, AI, TD, CAV, H1 and PSV(f,5%) (19,961 components, 2629 events, 547 stations). Merging small and moderate magnitude events produced a unique database capable of providing important information such as: (i) Correlations between several ground motion parameters follow analogous trends as in previous worldwide datasets, with slight corrections. (ii) Although PGA attenuations with distance show great uncertainties, four recent GMPEs recommended for Europe fit quite well the central 50% data interval for the distance range 10 〈 R 〈 200 kin; outside these distances, they do not fit. (iii) Soil amplification ratios indicate that weak motion (low magnitudes and larger distances) shows larger amplification than strong motion (short distances and large magnitudes) as represented in UBC97 for the USA, but not in EC8 for Europe. (iv) Average spectral shapes are smaller than in the EC8. (v) Differences in amplification factors for PGA, PGV and HI for EC8 soil classes B and C, and differences in spectral shapes for these soil classes, indicate that EC8, Type 2 S-coefficient should be frequency dependent, as in UBC97.展开更多
