Source: R/BSSA14.R
BSSA14.Rd

BSSA14 returns the ground-motion prediction with it sigma of Boore et al.(2014) GMPE.

Usage

BSSA14(Mag, Rjb, Prd, Vs30, ftype = 0, Z1.0, regionflag = 0, basinflag = 0)

Arguments

Mag

Earthquake momnet magnitude, Numeric.

Rjb

Joyner and Boore distance(km), Numeric.

Prd

Period of spectral acceleration.

Vs30

Vs30(m/s).

ftype

style of faulting.

Z1.0

the depth to the shear-wave velocity horizon of 1.0(km/s).

regionflag

Regional attenuation flag, 0 = Global, 1 = China-Turkey, 2 = Italy-Japan.

basinflag

Basin Adjustments.

Value

A list will be return, including mag, Rjb, specT, period, lnY, sigma, iflag, Vs30, ftype, pga4nl, Z10, regionflag, basinflag, phi, tau.
