The following are the parameters that the current CyberShake workflow uses. We'd like to use similar parameters for an AWP-ODC CyberShake workflow and would expect to get similar results.

Grid box
- 420 km x 620 km x 40 km deep
- 200 m spacing
- Box rotated -55 degrees
- Corner coordinates:
x=0, y=0: (34.5491, -122.11248) x=420, y=0: (37.696, -119.54488) x=420, y=620: (34.444, -113.95284) x=0, y=620: (31.41553, -116.62562)
Velocity mesh
- CVM-4
- VpMax = 16.7 km/s
- VsMax = 13.9
- RhoMax = 12.9
- VpMin = 1.7
- VsMin = 0.5
- RhoMin = 1.7
Velocity files were checked for poisson ratio (ask Rob for more details).
SGT calculation
- nt = 8000
- dt = 0.01
- qsfrac=50
- qpfrac=100
- qpqsfactor = 2.0
- fmax = 25.0, fmin = 0.01
- flo = 0.5, fhi = 0.0
There are other parameters, but I'm not sure which are related to Rob's code in particular and which are more general.
SRFs for forward and inverse comparison
- Puente Hills (Santa Fe Springs)
- Magnitude 6.15
- Source 245, Rupture 2, Rupture Variation 0
- SRF file available here
- Southern San Andreas
- Magnitude 8.25
- Source 89, Rupture 5, Rupture Variation 0
- SRF file available here
- 1994 Northridge
- Magnitude 6.7
- Not in UCERF2
- SRF file available here
