Hadley Kanamori 1D model is used for various purposes in SCEC research, and by seismic networks in California.
SCSN Hadley-Kanamori 1D Model
The layers and Vp values in the SCSN HK model are given below. SCSN uses a Vp/Vs ratio of 1.73
Top of Layer (km) P-Velocity (km/sec) 0.0 5.5 5.5 6.3 16.0 6.7 32.0 7.8
A paper that cites the model and defines the layers.

SCEC Hadley-Kanamori 1D Model Definition
SCEC uses a modified version of the HK model as a background model in their 3D velocity models. This means that if you query some of the Calfornia CVM's outside their defined coverage region, the CVM will return values from the HK model. In general, CVM tools will use linear interpolate between layers, so material properties returned vary gradually between model layers.
The following plot shows the SCEC HK 1D model:
# 1D Velocity Model configuration # # Vp is interpolated between layer n to n+1. # Rho is derived from vp (./src/ucvm/ucvm_model_1d.c) # Vs is derived from Vp and Rho (./src/ucvm/ucvm_model_1d.c) # version=Hadley-Kanamori 1D (CVM-S) # Depth of model in layers num_z=9 # Depth to start of layer (km) depth_vals=1.0, 5.0, 6.0, 10.0, 15.5, 16.5, 22.0, 31.0, 33.0 # Vp at start of layer (km/s) vp_vals=5.0, 5.5, 6.3, 6.3, 6.4, 6.7, 6.75, 6.8, 7.8
