Plot of radial (upper panel), transverse (middle panel), and vertical (lower panel) component acceleration time histories recorded at site AIC004 (see Fig. 1 for location) for the 2004 (upper trace in each panel) and 2016 (lower trace in each panel) events. The recordings are aligned to match the S-wave arrivals. The arrivals of P- and S-waves are indicated by the letters P and S, respectively. The hypocentral distance (R) is rounded to the nearest whole number. See Fig. 4 for the velocity seismograms at the site and Fig. 9 for a comparison of the adjusted PGAs and PGVs among the sites used
