)Arguments
- Mag
Earthquake momnet magnitude, Numeric.
- Rrup
Rupture distance(km), Numeric.
- Rjb
Joyner and Boore distance(km), Numeric.
- Prd
Period of spectral acceleration.
- Vs30
Vs30(m/s).
- Dip
Dip angle of the fault plane.
- Ztor
Depth to the top of the finite rupture model (km).
- ftype
style of faulting.
- Z1.0
the depth to the shear-wave velocity horizon of 1.0(km/s).
- Vs30_class
1 measured, 0 estimated.
- hwflag
hanging-wall flag, 1 for hanging-wall.
- Rx
Horizontal distance(km) from top edge of rupture. Measured perpendicular to the fault strike.
- regionflag
0 Global, 1 Japan and Italy, 2 Wenchuan (note only for M7.9)
