StreamPick

This Project is not supported anymore, see http://pyrocko.org Snuffler for seismic data inspection and picking!

A leightweight PyQt frontend to pick seismic wave arrival times in traces contained in an ObsPy Stream object. For further processing the picks can be treated in ObsPy or exported to QuakeML format (see obspy.core.event and https://quake.ethz.ch/quakeml/).

Running the Program

A Stream object is created and passed to streamPick.

from obspy import read
from streamPick import *

st = read('test.mseed')
new_picks = streamPick(st)

new_picks.getPicks()
>>> List of obspy.core.event.Pick objects

You can save the picks as a QuakeML catalog. And handle the catalog through ObsPy:

from obspy.core import event

cat = event.readEvents('myPicks.xml')

Usage

StreamPick Gui. Navigate through the timeseries with the Mouse wheel: Click and Drag the plot to move in time, use the mouse wheel to zoom in and out.

streamPick-gui

Mouse click and key Q sets P-Wave, W S-Wave arrival. Click and push T for custom wave phase, hit R to remove picks from trace.
