<p>scanloc for <cite>SeisComP</cite> <span id="id1">[<a class="reference internal" href="references.html#id292" title="Helmholtz-Centre Potsdam - GFZ German Research Centre for Geosciences and gempa GmbH. The SeisComP seismological software package. GFZ Data Services. 2008. URL: https://www.seiscomp.de, doi:10.5880/GFZ.2.4.2020.003.">39</a>]</span> is optimzed for monitoring local and
|
|
micro seismicity within small as
|
|
well as large seismic monitoring networks in low and high seismicity environments.
|
|
Typical networks consist of 5 to 20 stations
|
|
and sometimes even many more were the station distances are in the range of
|
|
hundreds of meters to tens of kilometers.</p>
|
|
<p>scanloc makes use of the cluster search algorithm DBSCAN <span id="id2">[<a class="reference internal" href="references.html#id125" title="DBSCAN. Data clustering algorithm. URL: http://en.wikipedia.org/wiki/DBSCAN.">2</a>]</span> to
|
|
associate detected seismic phases to one or many potential seismic events.
|
|
While the cluster search itself is based on P phases only, in a second step S
|
|
picks and more P phases are associated to better locate the event.</p>
|
|
<p>In order to provide high-quality picks from S phases, a new
|
|
<a class="reference internal" href="sphase-detector.html#scanloc-spicker"><span class="std std-ref">S-phase picker</span></a> is distributed
|
|
along with scanloc. The S picker allows to identify S phases on the horizontal
|
|
components or on the vertical components if the horizontals should be unavailable.
|
|
A <a class="reference internal" href="sphase-detector.html#scanloc-spick-debugger"><span class="std std-ref">user-friendly debugger GUI</span></a> allows the interactive
|
|
tuning of the S picker configuration parameters based on waveforms.</p>

|
<p><a class="reference internal" href="auxiliary.html#sec-scanloc-aux-tools"><span class="std std-ref">Additonal auxiliary tools</span></a> ship with the scanloc

package to support detailed tuning and realistic playbacks.</p>
