The study presented in Razafindrakoto et al. (2018; hereafter, RBG2018) presents hybrid broadband (0–10 Hz) ground‐motion simulations for the 2011 Mw 6.2 Christchurch, New Zealand, earthquake. The authors utilize a 3D velocity model and a kinematic source model with stochastic realizations of the slip amplitude, rise time, and rake angle, and the resulting ground motions capture the salient basin amplification effects observed in Christchurch.

In addressing the limitations of empirical approaches and presenting the advantages of physics‐based numerical simulations for ground‐motion prediction, RBG2018 refer to one of our previous works, namely Guidotti et al. (2011; hereafter, GU2011). A...
