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
