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.

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:

# 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)
