Introduction
|
|
============
|
|
|
|
scanloc for |scname| :cite:p:`seiscomp` 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.
|
|
|
|
scanloc makes use of the cluster search algorithm DBSCAN :cite:p:`dbscan` 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.
|
|
|
|
In order to provide high-quality picks from S phases, a new
|
|
:ref:`S-phase picker <scanloc-spicker>` 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 :ref:`user-friendly debugger GUI <scanloc-spick-debugger>` allows the interactive
|
|
tuning of the S picker configuration parameters based on waveforms.
|
|
|
|
:ref:`Additonal auxiliary tools <sec-scanloc-aux-tools>` ship with the scanloc
|
|
package to support detailed tuning and realistic playbacks.

Applications
|
|
------------
|
|
|
|
scanloc is a backbone module in |scname| systems for many applications including
|
|
|
|
* Real-time monitoring of local and regional earthquakes,
|
|
* Re-processing of historical data for more complete seismicity catalogs,
|
|
* Monitoring of natural and induced seismicity in industrial environments e.g. at
|
|
|
|
* geothermal plants,
|
|
* oil and gas production,
|
|
* underground gas storages,
|
|
* open and deep mines,
|
|
|
|
* Integration of :ref:`teleseismic events<scanloc-zero-weight>` detected by
|
|
local monitoring networks
|
|
* :ref:`Association of P and S phases <scanloc-assoc>` to detections by other
|
|
instances e.g. :cite:t:`ccloc` or :cite:t:`lambda`.

Examples from science
|
|
---------------------
|
|
|
|
scanloc has been routinely applied, demonstrated, promoted and discussed with
|
|
scientists and the SeisComP community in scientific publications and at
|
|
international science conferences.
