Comparison of the theoretical amplification for 32 sites according the NEHRP site classifications. a site class B and E, b-c site class C, d site class D. The amplification values are computed using 1D transfer functions for vertically incident SH waves. The engineering bedrock S-wave velocity is Vs = 780 m/s. The Q value is assumed to be 1/15 of Vs (Q = Vs/15). Site class C divided into two subgroups according to velocity ranges C1, 450 < AVs30 < 600 m/s and C2, 350 < AVs30 < 450 m/s
