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
