GAZI: Get azimuthal particle motion

Description

Do particle motion analysis

Usage

GAZI(ADAT, dt = 1, ex = seq(0, 100), comp = c(4, 5, 6), sta = "ZZZ", az = 0, len = 50, shift = 10, prev = 1, fileid = "", picks = NA, labs = NA)

Arguments

ADAT

Matrix of 3 component seismic data

dt

delta T (s)

ex

x-axis vector

comp

component names

sta

station name

az

azimuth of station orientation

len

length of time series

shift

prev

fileid

picks

arrival times for annotation

labs

labels for arrival times for annotation

Value

• list(aex=aex[1:jall], rateig=rateig[1:jall], aaz=aaz[1:jall], ai=ai[1:jall], figaz=figaz, azpar=azpar, incpar=incpar )

Examples

data("GH")


temp = cbind(GH$JSTR[[4]], GH$JSTR[[5]], GH$JSTR[[6]])

pmolabs=c("Vertical", "North", "East")


 G  = GAZI(temp, dt =GH$dt[4]  , comp = pmolabs, sta = GH$STNS[4] , az = 0, len =75, shift = 10, prev = 1)
