Comparison of peak ground accelerations (PGAs), a, and peak ground velocities (PGVs), b, observed for the 2004 (black circles) and 2016 (red circles) events. The blue and green crosses denote the values at site AIC004 for the 2004 and 2016 events, respectively. Similarly, the blue and green triangles denote the values at site AICH15 for the two events. The gray and pink solid lines denote the median predictions using the GMPEs (Morikawa and Fujiwara 2013) for the 2004 and 2016 events, respectively. The dashed gray and pink lines show a range of one standard deviation for the corresponding events. The observed values were adjusted for site amplification effects for both events, and the anomalous path effect due to the subducting Philippine Sea Plate for the 2004 event. Note that the correction for the anomalous path effect due to the subducting plate is required only for recordings from events located inside the oceanic plates
