Goal: Create NorCal CyberShake Mesh for SW4

Mesh Region

Region should match the SFBR model https://www.usgs.gov/programs/earthquake-hazards/science/3-d-geologic-and-seismic-velocity-models-san-francisco-bay

  • ne_coord (-122.562365, 39.174505)
  • nw_coord (-123.858493, 38.424179)
  • sw_coord (-121.922036, 36.320331)
  • se_coord (-120.644051, 37.050062)
  • spacing=25.0

Config Script

  • input 4 corners (and projection) and spacing
  • calc rotation angle
  • distance between points
  • calculate nx, ny, nz based on spacing

Define Region

  • origin
  • rotation angle
  • distance x
  • distance y
  • distance z
  • spacing

Low Res UCVM2Mesh Configuration for SFBR Model

To test our mesh formats for SW4, we will test with a low resolution

  1. rot=-53.9
  2. x0=-123.858493
  3. y0=38.424179
  4. z0=0.0
  5. spacing=500.0
  6. nx=
  7. ny=
  8. nz=
  9. Dist x = 140
  10. Dist y = 280
  11. Dist z = 40

UCVM2Mesh Configuration for SFBR Model

  1. rot=-53.9
  2. x0=-123.858493
  3. y0=38.424179
  4. z0=0.0
  5. spacing=25.0
  6. nx=1280
  7. ny=640
  8. nz=320
