CyberShake 1D Model

The following plots show a 1D velocity model that we will use for our CyberShake 14.2 Production run. This is a layer model. We will linearly interpolate the layers with this rule: Vp,Vs, and rho values are linearly interpolated between layer n to n+1.

Linearly Interpolated BBP 1D model with 1km Moho Velocity Profiles

Below are plots showing Vp, Vs, and rho from the selected 1D model.

Linearly Interpolated Broadband Platform 1D model with 1km Moho to 60km Depth	Linearly Interpolated Broadband Platform 1D model to 5000m Depth

Linearly Interpolated BBP 1D model with 1km Moho Overlay Plots

Below are plots showing 1D profiles extracted from CVM-S4 for the 386 CyberShake sites in the study, with the selected 1D model plotted on top of this collection of profiles.

Z1.0 and Z2.5 Values

The Z1.0 depth is 22.5 meters.
The Z2.5 depth is 3500 meters.
