In RSEIS: Seismic Time Series Analysis Tools

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
