Fig. 9From: Numerical earthquake model of the 20 April 2015 southern Ryukyu subduction zone M6.4 event and its impact on seismic hazard assessmentComparison between the norm of all three components of the observed PGA and the simulated ShakeMap. PGA observations are shown with colored triangles, and were compiled from the CWB 24-bit Real-time Seismic Monitoring Network. The observations were low-pass filtered using a corner frequency of 0.625 Hz to compare results with the simulated ShakeMap determined by a frequency of ≤0.625 HzBack to article page
