Fig. 2: PGA maps predicted by the physics-based simulation (PBS) method and empirical ground motion prediction equations (GMPEs).
From: Can we develop a more targeted approach to mitigating seismic risk?
a–d The simulated PGA distribution maps for the four earthquake scenarios on the Jiaocheng Fault by using the curved grid finite-difference method (CG-DFM). The black pentacle in each panel represents the epicentre that initiates the rupture process of each scenario earthquake. e–i PGA maps generated by the empirical GMPEs of “BA08”46, “CB08”47, “BSSA14”48 and “CB14”49.
