The GMPE of Zea 2016 for interface event

Description

This function calculates the ground motion median values and standard deviations

Usage

zea_2016_Sub_Interf(mag, T = 1000, fDepth, dist, DistV, SiteClass)

Arguments

mag

Moment magnitude, a numeric value

T

Period (sec) (range should be between 0.005 s and 5 s). Use 1000 (by default) for output the array of Sa with original Zhao et al per-defined periods

fDepth

Depth(km) to the top of ruptured plane (km)

dist

The closest distance (km) to rupture plane when is available, otherwise hypocentral distance.

DistV

The distance of volcanic path (km)

SiteClass

The site class: 1 for SC I, 2 for SC II, 3 for SC III 4 for SC IV sites. The relationship between site class and Vs30 is given by Zhao et al., 2016 (https://doi.org/10.1785/0120150056). SC I: Vs30 > 600 m/s; SC II: 300 < Vs30 =< 600 m/s; SC III: 200 < Vs30 =< 300 m/s; SC IV: Vs30 <= 200 m/s

Value

A list of six elements is returned: Sa - median spectral acceleration prediction (in g); RockSa - median spectral acceleration prediction on Rock reference site (in g); SiteAmp - Site amplication response spectral (subtraction in log(g)); sigma - totla standard deviation; phiSS - single station standard deviation; period - the corresponding oscillator periods
