\begin{abstract}
The ShakeOut scenario of a M7.8 northwestward rupture on the southern
San Andreas fault (SSAF) (Jones et al., 2008) predicted significant
long-period ground motion amplification in the greater Los Angeles, CA,
area, caused by a waveguide from interconnected sedimentary basins.
However, the early ShakeOut ground motion simulations omitted important
model features with immature versions of the velocity structure and
fault geometry. Here, we present 0-1 Hz 3D numerical wave propagation
simulations for the ShakeOut scenario including surface topography, as
well as updated high-resolution velocity structure and SSAF fault
geometry. Spectral Accelerations at 3s are increased by the local
high-resolution basin models (25-45\%) but decreased from complexity in
velocity and density updates outside the basins (65-100\%) and inclusion
of surface topography (\textasciitilde{}30\%). The updated model reduces
peak ground velocities in the waveguide from \textasciitilde{}250 cm/s
to \textasciitilde{}100 cm/s, significantly closer to the values
predicted by a leading NGA-West2 ground motion model.%
