Required Parameters: 
Earthquake Rupture
  • Magnitude (MW)
  • Fault Type: [Strike-Slip or Normal, Thrust (dip < 45°), Reverse (dip > 45°), Thrust or Reverse, Unknown]
Site
  • Site Type [Firm Soil, Very Firm Soil, Soft Rock, Firm Rock, Generic Soil, Generic Rock, NEHRP BC]
  • Campbell Basin Depth (Depth in km to Cretaceous, crystalline basement, or 3 km/sec S-wave velocity)
Propagation-Effect
  • DistanceSeis
  • Hanging Wall Parameter (1.0 if site is within surface projection of rupture, tapering (linearly) to 0.0 at 5 km beyond)
Other
Parameter values are numeric unless otherwise indicated with options. If only one option is presented, the value is fixed for this attenuation relationship.
Model Details: 

The mean calculation for the site class "BC Boundary" is only approximate at 0.05- and 0.075-second periods (because "bv" is not available from Boore, Joyner, and Fumal (1997) at those periods, so values were linearly interpolated between 0 and 0.1 seconds) and at 3- and 4-seconds ("bv" not available from Boore, Joyner, and Fumal (1997) above 2 seconds, so value at 2-seconds was applied).
