.SH NAME
scanloc \- scanloc: Phase Associator Documentation
.sp
\fBModule for locating local earthquakes and man\-made seismicity by DBSCAN
cluster search.\fP
.SH DESCRIPTION
.SS Low\-threshold monitoring
.sp
\fIscanloc\fP associates detected P and S phases from local and regional earthquakes
and other seismic events for locating. It determines initial hypocenter
solutions by cluster search based on DBSCAN [\fI\%2\fP]\&. Additional P and S phases are associated
to existing internal solutions from cluster search or solutions incoming through the messaging
system from external modules.
.sp
Due to the clustering and subsequent phase association scanloc facilitates low\-threshold
monitoring of high\- and low\-rate seismicity with high accuracy.

.SS Travel\-time tables
.sp
The scanloc package ships with \fI\%densely sampled travel\-time tables\fP for
\fILOCSAT\fP [\fI\%5\fP] based on the IASP91 Earth model to enhance locating local earthquakes.
.SS S phases
.sp
In order to deliver high\-quality picks from S phases, the \fI\%scanloc\fP package
also includes the \fIsaic\fP plugin with the enhanced \fI\%S\-phase picker\fP\&.
The S\-phase picker can be applied to detect S phases on the horizontal components
or on the vertical component in case of 1\-component sensors. In addition the scanloc
package comes with the \fI\%graphical debugger for the S\-phase picker\fP
provided by the \fIspickdbg\fP plugin.
.SS Array measurements
.sp
Detections from array measurements including detection time, slowness and
back azimuth can be fully considered by \fI\%scoring\fP
depending on the applied locator.
.SS Auxiliary tools
.sp
The scanloc package also ships with auxiliary Python script for
\fI\%real\-time or non\-real\-time playbacks\fP or tuning. Read the
\fI\%dedicated section\fP for more details.

.INDENT 3.5
scanloc processes picks with unique public IDs. However, the accuracy of
public IDs currently generated by \fIscautopick\fP [\fI\%15\fP] is limited to
10 ms by default. In systems with very frequent picks and in
\fI\%pipeline systems\fP
this limitation may result in clashes. Therefore, we recommend to let
scautopick use the same high\-resolution public ID scheme as all
other modules by configuring the ID pattern explicitly in global module
configuration (\fBglobal.cfg\fP):

.SS Clustering
.sp
In case the pick cannot be associated, the cluster search is started. The
cluster search is based on the algorithm \fIDBSCAN\fP [\fI\%2\fP] which
takes the required number of neighbours (\fI\%clusterSearch.minSize\fP)
and \fI\%clusterSearch.maxSearchDist\fP as configuration parameters.
.sp
The algorithm forms clusters of picks by searching for neighboring stations
that have picks. \fI\%Internal origins\fP are formed from clusters.
The number of origins from cluster search is limited by the configuration parameter
\fI\%clusterSearch.maxOrigins\fP\&.
.sp
The cluster search considers picks from stations by distance with:
.sp
.ce
distance \ele maxSearchDist
.ce 0
.sp
where maxSearchDist is configurable by \fI\%clusterSearch.maxSearchDist\fP\&.
distance is the vector sum of the time difference \eDelta t
between the picks in units of seconds and of a potential travel time
tt between the stations in units of seconds:
.sp
.ce
distance = \esqrt{\eDelta t^2 + tt^2}
.ce 0
.sp
and
.sp
.ce
tt = \eDelta x / v
.ce 0
.sp
where \eDelta x is the horizontal distance between the sensor locations
of stations in units of km and v is the
\fI\%clusterSearch.averageVelocity\fP in units of km/s. Activate
\fI\%use3D\fP for considering 3D distances between sensor
locations. Therefore, distance and
\fI\%clusterSearch.maxSearchDist\fP take units of seconds.
.sp
As the cluster search is done over time and location, the additional configurable
velocity parameter, \fI\%clusterSearch.averageVelocity\fP, is required to transform
the input parameters of the cluster search in the same dimension (time).
The velocity is a weighting factor between inter\-station distances and
travel\-time differences. A starting value should represent the average apparent
horizontal or the total medium P\-wave velocity of the crust.

In real time picks are received in the order of their creation times. They are
considered for clustering if their pick times are within a time window
before the \fBcluster reference time\fP\&. The time window is defined by
\fI\%clusterSearch.maxPickDelay\fP but the \fBcluster reference time\fP is defined
either by the
.INDENT 0.0
.IP \(bu 2
Pick time of the latest pick of the received picks when
\fI\%clusterSearch.referenceTimeMode\fP = \(aqLastPick\(aq (default),
.IP \(bu 2
Pick time of the latest received pick which defines are group of \fIN\fP
picks within \fI\%clusterSearch.maxPickDelay\fP when
\fI\%clusterSearch.referenceTimeMode\fP = \(aqMaxPickDelay\(aq. Here, \fIN\fP is the
maximum of \fI\%clusterSearch.minSize\fP
and \fI\%association.minPhase\fP\&. \fBThis mode is relevant if only very few
stations with significantly different data delay provide the picks.\fP
Otherwise picks may not be available for clustering at the same time
preventing to form clusters and new origins.
.UNINDENT
.sp
Thus, when setting \fI\%clusterSearch.referenceTimeMode\fP = \(aqMaxPickDelay\(aq
re\-setting the cluster reference time is delayed depending on the amount and
density of incoming picks. With this option picks which have a larger delay can
be considered. Such delays occur, e.g., due to larger data delays or larger
record lengths.

Picks available within a trapezoid\-like time window are considered for
clustering.
For a pick with zero delay, the cluster reference time is initially set and picks
within the \fBblue trapezoid\fP (figure below) are considered.
Normally, picks have some delay which delays defining the trapezoid. This makes accessible
other picks available with some delay, too, allowing these picks to be considered
(\fBgreen trapezoid\fP). Subsequently, the trapezoid is extended until the
cluster reference time is updated.
This may be the next pick with a larger pick time
(\fBolive trapezoid\fP, \fI\%clusterSearch.referenceTimeMode\fP = \(aqLastPick\(aq) or
the time of the pick which is preceded by at least \fI\%clusterSearch.minSize\fP
picks within \fI\%clusterSearch.maxPickDelay\fP (\fByellow trapezoid\fP,
\fI\%clusterSearch.referenceTimeMode\fP = \(aqMinPickDelay\(aq).
Thus, picks which have a long delay do not fall within the relevant trapezoid and
cannot be considered for clustering as they are not available at the time of clustering.
.sp
The trapezoid is set with respect to the cluster reference time, CRT1 in the figure below,
considering the delay of the defining pick and the time until the next relevant
pick which updates the reference time (CRT2):

clustered pick in the figure below.

In XML playbacks, the creation times may not be representative of
real\-time conditions. Therefore, pick times may be used for the timing instead
of creation times. Read the section \fI\%Real\-Time Applications\fP for more details

If picks arrive with a larger delay than others, there is a risk that they cannot
be considered anymore for the cluster. When only few picks are available the events
may then be missed. To overcome the issue, you may increase \fI\%clusterSearch.maxPickDelay\fP
or set the parameter \fI\%clusterSearch.referenceTimeMode\fP = \(dqMaxPickDelay\(dq.
While increasing \fI\%clusterSearch.maxPickDelay\fP may slow down the clustering
and increase the risk to cluster unrelated picks,
\fI\%clusterSearch.referenceTimeMode\fP = \(dqMaxPickDelay\(dq will only increase the
cluster reference time if at least \fI\%clusterSearch.minSize\fP P picks are
available in the considered time window. Run \fBscanloc\fP on the command line
with the \fI\%\-\-cluster\-search\-log\-file\fP to learn about cluster reference
times and the considered picks. A suggestion for \fI\%clusterSearch.maxPickDelay\fP
is provided in the summary section at the end of the resulting output. For more
options read the section \fI\%Tuning and optimization\fP\&.
.sp
Within one cluster, the difference in the pick times between the
cluster reference time and any other pick must thus not exceed \fI\%clusterSearch.maxPickDelay\fP\&.
Otherwise the pick is rejected from clustering. The parameter \fI\%clusterSearch.maxPickDelay\fP
has a big impact on the performance of the cluster search. Choosing the parameter
as small as possible will speed up scanloc and will reduce the complexity of the
cluster search.
.sp
The DBSCAN algorithm can deliver multiple pick clusters. The cluster search can
be disabled using \fI\%clusterSearch.maxPickDelay\fP:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
# Maximum allowed difference between P pick and cluster reference time(latest pick time).
# The cluster search ignores all picks which exceed the value. Using \(dq\-1\(dq enables all picks
# regardless of the delay. Unit: seconds.

clusterSearch.maxPickDelay = 0
.ft P
.fi
.UNINDENT
.UNINDENT
.sp
Then, only \fI\%external origin\fP can be considered for
\fI\%phase association\fP\&.
.sp
In combination with \fI\%buffer.futureTimeDelta\fP or
\fI\%\-\-future\-time\-delta\fP
applying \fI\%clusterSearch.referenceTimeMode\fP = \(dqMaxPickDelay\(dq may make
updating the cluster reference time more robust to singular data timing issues.
However, the timing issue of the waveforms and the pick times remain and may
impact the clustering itself. Therefore, \fI\%buffer.futureTimeDelta\fP
should only be configured with positive values only in extraordinary
circumstances.
.SS Limiting in space
.sp
The cluster search can be constraint to stations within a region given by the
coordinate of a central point and the radius around that point. The region constraint
is configured through \fI\%clusterSearch.regionFilter\fP\&. Applying this parameter
will disregard picks from stations outside the region for cluster search increasing
the speed and the complexity. Nevertheless, the excluded picks are available for
\fI\%phase association\fP\&.
.sp
For running the cluster search in several regions in parallel, different instances
of scanloc taking picks from the same of different pickers can be created and started.
.SS Cluster splitting
.sp
Originally, clusters may contain multiple phase picks from the same sensor but
only one pick per sensor shall be accepted. Therefore, the clusters with picks
from the same sensor are split into separate clusters with only one pick per
sensor.
.sp
Typcially, the sensors are discriminated by their sensor location codes, LOC, as
defined in the SEED manual [\fI\%29\fP] using the NET.STA.LOC.CHA stream
representation. Since some stations provide data for different sensors on the
same sensor location code but with different channel codes (e.g. seismic and
infrasound sensors), the channel code, CHA, may be a better discrimination
measure for sensor identity. On the other hand, picks made on different sensor
location of the same station could be attributed to the same site, e.g., in
regional or telseismic monitoring. Then, the station code, STA, would be
preferred for discrimination. The parameter
\fBclusterSearch.streamCheckLevel\fP allows defining the stream level on
which to check sensor identity.

Clusters not meeting the configured cluster criteria are removed from the buffer.
The check imposes an additional overhead on the cluster search but it typically
lowers the chance for fake solutions and it also lowers the load on the
\fI\%phase association\fP and scanloc in general.

fails or the event residual is larger than \fI\%maxRMS\fP,
the S pick is associated with a weight of 0. The score of the resulting
origin is compared with scores of origins belonging to the same event. In case
the score is higher than the rest of the origins, the origin is
\fI\%sent out\fP\&.
.sp
In addition to origins from the cluster search, \fIscanloc\fP can also treat external
origins that are created by other associators, e.g., \fIscautoloc\fP [\fI\%14\fP]\&.
In case an such origin is received \fIscanloc\fP tries to associate all picks in the
buffer to the origin. The association and the following processes are the same as
described above. See figure \fI\%Simplified work flow of scanloc.\fP for an overview.
.sp
The maximum epicentral distance up to which picks are considered is configured
by \fI\%association.maxDist\fP\&. However, this parameter can be overruled per
network and station by providing a station table in a file given by
\fI\%association.stationConfig\fP\&. As in \fIscautoloc\fP [\fI\%14\fP] each line of the
table consists of the network code, the station code, a switch and the maximum
epicentral distance in degrees. Wildcards can be used for the network and the
station code. The switch causes the associator to consider (=1) or to ignore
(=0) a network or a station.
The last occurrence of an item in a table overrules previous ones, e.g.

In case of dense large\-N networks and high seismicity situations,
very many phase picks, e.g., hundreds of picks for a single event may be
provided to and processed by scanloc. In such situations, scanloc was observed
to slow down with default parameters but a sensible configuration of
\fI\%clusterSearch.maxSize\fP and \fI\%association.arrivalCountMinRes\fP
could overcome the obstacles.
.INDENT 0.0
.IP \(bu 2
.INDENT 2.0
.TP
.B \fIclusterSearch.maxSize\fP controls the maximum number of picks in a cluster
after selecting core points and before adding more picks. Since core points
are first collected, clusters may have a higher number of picks. The goal of
this parameter is to speed up scanloc. The parameter may help to increase the
performance of scanloc in case of dense large\-N networks where very many
cluster can be formed due to the proximity of stations or generous
configuration.
.UNINDENT
.IP \(bu 2
\fIassociation.arrivalCountMinRes\fP controls the association of picks to origins.
For origins with a larger number of arrivals than configured, the association
of P and S picks is controlled by the minimum of (\fIassociation.maxPResidual\fP,
\fIassociation.maxResidual\fP) and (\fIassociation.maxSResidual\fP,
\fIassociation.maxResidual\fP), respectively. The goal of this parameter is to
speed up scanloc by only associating picks to already stable origins defined
by many arrivals where new picks later on are unlikely to be removed again
from origins by residual checks. The parameter may help to increase the
performance of scanloc in case of dense large\-N networks where very stations
provide phase picks.

.SH ASSOCIATION OF TELESEISMIC PHASES
.sp
Dense local networks used to monitor local seismicity are often able to catch
also a significant number of phases from earthquakes at teleseismic distances.
Such phases include Pdiff or PKP.
Especially PKP may contain a significant amount of energy at higher frequencies.
Therefore PKP is often detected by networks that are tuned to detect
local earthquakes.
Due to the steep incidence and the low horizontal slowness of these phases, they
are sometimes located as fake deep earthquakes below the network.
\fIscanloc\fP can be used to suppress this type of fake events.
.sp
In a 2\-pipeline setup, \fIscanloc\fP can associate such teleseismic phases recorded
by the local network with origins that were found by the pipeline for
monitoring teleseismic earthquakes. Then \fIscevent\fP [\fI\%19\fP]
will associate
the origins from the teleseismic pipeline with the fake origins from the
pipeline for local monitoring to the same event. The assumption is that the origins
from the teleseismic pipeline win over the origins from pipeline for local monitoring
because they have more associated arrivals. In this case the origins from pipeline
for teleseismic monitoring that has most phases becomes the preferred origin for
the event. This \fI\%scanloc\fP feature requires an extended license.

.SH PLAYBACKS
.sp
Playbacks are used to process waveforms or other data on demand as in real time
or non\-real time, with or without connection to the \fISeisComP\fP messaging. Objects
like picks and origins may be provided to scanloc by XML files or through the
messaging.
.sp
In playbacks of picks in XML files the performance of scanloc may differ
from real\-time operation based on messaging:
.INDENT 0.0
.IP \(bu 2
In real\-time operation, the picks are made e.g., by \fBscautopick\fP at
some time and considered by scanloc according to
their creation times. Delayed picks may become irrelevant for the processing.
Configure \fI\%buffer.pickKeep\fP and \fI\%buffer.originKeep\fP accordingly.
.sp
However, the \fBcreation times of picks and origins may be obscured\fP when
created in a non\-real\-time playback or manually. Objects from non\-real\-time
playbacks may have almost identical creation times independent of their object
times (pick time, origin time, etc.).
.IP \(bu 2
\fI\%In message\-based playbacks\fP, picks and
origins are provided to scanloc via the messaging system. When created in real
time, the \fBcreation times\fP of these objects form a
realistic time reference for scanloc and should therefore considered using
\fI\%\-\-timing\fP\&.
.IP \(bu 2
\fI\%In non\-real\-time XML playbacks\fP
(\fI\%\-\-ep\fP), scanloc considers picks and origins by default according to
their actual \fBtimes\fP\&.
For objects created in a non\-real\-time playback object times are most
reasonable as creation time is not a valid time reference anymore.
\fBHowever, referencing to object time may result in a behavior which is
different from real\-time conditions.\fP

.B association.stationConfig
Type: \fIfile\fP

The station configuration file contains lines consisting of
network code, station code, weight (0 or 1) and maximum
association distance given in degree. The maximum association
distance is the distance in degrees from the origin up to
which this station may contribute to a new origin. This
parameter overrides the global parameter
\(dqassociation.maxDist\(dq.
If this distance is 180 deg, this station may contribute to
new origins world\-wide. However, if the distance is only 10
degree, the range of this station is limited. This is a helpful
setting in case of mediocre stations in a region where there
are numerous good and reliable stations nearby. The station
will then not pose a risk for locations generated
outside the maximum association distance. The last item found
in the list overrules previous ones.
Network and station codes may be wildcards (*) for
convenience. Example:

The number of arrivals of an origin for controlling the

The parameter also speeds up the evaluation of origins with
more arrivals than configured: Instead of
testing residuals of arrivals individually and relocating
thereafter, all arrivals not passing the residual check are
removed in a bulk.
.sp
The parameter is meant to support large\-N networks where the
high network density results in very many picks and high
computational load, effectively slowing down the quality
check of picks. Setting a reasonable value, e.g., >20 will
only associate the best picks to origins already well

.sp
Timing reference in offline processing with \-\-ep: Use
pickTime and creationTime for sorting picks according to
pick time and creation time, respectively. pickTime is
assumed if no timing is specified. Note: In real\-time
processing picks are treated as they arrive corresponding to
creationTime and this option is irrelevant.
