Attached figure compares observed peak ground velocity (PGV) with values from obtained from my initial 3D ground motion simulation. There are a total of 114 sites (CI network only) extending from just north of the international border to beyond the San Fernando basin (region covered by the simulation can be seen in the animation posted earlier today).

The rupture model used in this simulation (800-v1.0) has a moment of 7.8e+26 dyne-cm which gives a magnitude of Mw 7.22.
