Event Detection

Description

Event Detection for a seismic section

Usage

ETECTG(GH, sel = sel, FRWD = 8, BKWD = 8, sbef = 1, saft = 6, DFRWD = 0.5, DBKWD = 0.5, thresh = 2, Tthresh2 = 7, stretch = 1000, flo = 0.1, fhi = 5, PLOT = FALSE, Kmin = 7, perc = 0.05, kind = 1, DOARAIC = FALSE)

Arguments

GH Seismic Structure
sel select traces
FRWD forward window, s
BKWD backward window
sbef seconds before
saft seconds after
DFRWD seconds before
DBKWD seconds after
thresh threshold 1
Tthresh2 threshold 2
stretch stretch factor
flo low frequency for BP filter
fhi low frequency for BP filter
PLOT logical, TRUE=plot diagnostics
Kmin min number of picks per window
perc percentage of Kmin allowed
kind kind of picking
DOARAIC TRUE=do auto-regressive AIC method

Details

Very complicated picking routine - designed for volcanic regions with emergent arrivals. Works with lots of tuning.

Value

sel input selection
JJ index
PPTIM p-arrivals
PP all arrivals
