scwfparam¶

Waveform parametrization module.

Description¶

scwfparam is a SeisComP3 module that computes

peak ground acceleration (PGA)
peak ground velocity (PGV)
relative displacement elastic response spectrum (DRS)
pseudo absolute acceleration elastic response spectrum (PSA)

in real-time or offline. It includes a process scheduler and handles reprocessing of data in a smart way. It supports ShakeMap XML output as documented in the ShakeMap manual each time a new set of data is available.

Scheduling¶

When the module is not started in offline mode, the processing of events is scheduled following the configured rules. Parameters that influence the scheduling are:

wfparam.cron.wakeupInterval
wfparam.cron.updateDelay
wfparam.cron.delayTimes

The wake-up interval specifies when the scheduler is called to check if a process is about to be started or stopped. The default is 10 seconds.

The scheduler checks then all scheduled jobs, adds a job to the processing queue if the next run time is not in the future and removes all scheduled jobs with timestamps in the past. The process queue contains all jobs that are about to be executed. Because waveform acquisition is a time- and memory-costly operation only one process can run at a time. Once a process finished, the next process in the queue is executed (if any). When a process is started, it fetches the latest event parameters (origin time, magnitude, location).

To add processes to the scheduler, the module distinguishes two cases:

Process creation (new event or updated event seen the first time)
Process update (event updates after an process has been created)

Process creation¶

When a new event or an event update is received which does not have an associated process yet, a new process is created. The event time (Origin[Event.preferredOriginID].time) is used to build the default schedule according to wfparam.cron.delayTimes.

for each time in wfparam.cron.delayTimes:
  add_cron_job(process, Origin[Event.preferredOriginID].time + time)

Process update¶

If a process for an event already exists, the next run time is the current time plus wfparam.cron.updateDelay. Before adding this job to the scheduler the application checks if the next scheduled runtime is at least wfparam.cron.updateDelay seconds after the new run time. If not, a new job is not addded to the scheduler. Pseudo code to illustrate the strategy is given below.

event_updated(event):
  p = process_for_event(event)
  # The schedule for process p could be {T1,T2,T3,T4}
  now = get_current_time()
  next_run = now + wfparam.cron.updateDelay
  # Process currently suspended?
  if isEmpty(p.schedule):
    p.schedule.add(next_run)
  elif (p.schedule[0] - next_run) > wfparam.cron.updateDelay:
    p.schedule.prepend(next_run)
  else:
    # Do nothing, ignore the event update
    pass

Processing¶

The processing can be divided into the following steps:

Collect all stations within the configured maximum distance (wfparam.maximumEpicentralDistance or wfparam.magnitudeDistanceTable)
Remove already processed channels
Find the velocity and acceleration stream with the highest sampling frequency
- The sensor unit is used to distinguish between velocity and acceleration streams (M/S, M/S**2)
Use all allowed components (wfparam.streams.whitelist, wfparam.streams.blacklist) of each stream
Compute expected P arrival time if no pick is available
Start waveform acquisition
If the configured time window for one stream is complete, do (optional steps are written italic)
- Check saturation depending on wfparam.saturationThreshold
- Search maximum raw value (in counts)
- Apply gain
- Check STA/LTA threshold 5 seconds around P
- If velocity, differentiate data to acceleration
- Compute pre-event cut-off if enabled
- Compute offset of pre-event time window
- Compute signal duration and check for aftershocks
- Deconvolution using spectral division of FFT spectrum and transfer function
- Apply optional sensitivity correction filter (lo-, hi- or bandpass)
- Apply optional lo-pass, hi-pass or band-pass filter
- Compute PGA/PGV
- Calculate response spectra
If acquisition finished
- Collect all values (also recently processed values)
  - Results from velocity streams are always preferred over acceleration streams if both are available (eg. co-located stations)
- Generate ShakeMap event and station XML
  - Unless wfparam.output.shakeMap.maximumOfHorizontals is set to true all processed streams are included in XML
- Call ShakeMap script and pass eventID and event ID path

The channel is considered to be processed if the last step succeeded.

Waveform archival¶

If wfparam.output.waveforms.enable is set to true all processed waveforms are stored in the configured output directory wfparam.output.waveforms.path. The naming convention of a channel MiniSEED file is:

[EventDateTime]_[net]_[sta]_[loc][cha]_[filter][order]_[freqs].mseed

If wfparam.output.waveforms.withEventDirectory is set to true, an event directory with the eventID is created additionally where the channel files are stored under.

Either:

/path/to/waveforms/file1.mseed
/path/to/waveforms/file2.mseed
...

or

/path/to/waveforms/eventid/file1.mseed
/path/to/waveforms/eventid/file2.mseed
...

The MiniSEED file contains uncompressed float 4096 byte records.

Example:

Event time	2011-11-21 08:30:00 Network: CH
Station	SNIB
Location	_ _
Channel	HGZ
Filter	hi-pass
Order	2
Corner frequencies	0.025
Filename	20111121083000_CH_SNIB_HGZ_HP2_0.025.mseed

Database¶

scwfparam can make use of the database schema extension for strong motion parameters.

In order to prepare the database the extension schema must be applied. The database schema is installed in share/db/wfparam/*.sql. Login into the database backend and source the .sql file corresponding to the used database backend.

In order to enable scmaster to handle messages containing objects for strong motion parameters load the dmsm (data model strong motion) plugin as follows in scmaster.cfg:

plugins = ${plugins}, dmsm

scmaster must be restarted to activate the plugin.

To activate scwfparam to send messages with strong motion objects, set

wfparam.output.messaging = true

in scwfparam.cfg.

ShakeMaps¶

The ShakeMap XML is generated according the documentation of version 3.5 if wfparam.output.shakeMap.enable is set to true.

Below an example is given of an event XML and a station XML. The data was generated from a playback and does not describe a real event.

Examples¶

Running scwfparam offline with a multiplexed miniseed volume, an event xml and an inventory xml file. A hi-pass filter of 0.1hz (10secs) is used. Processing starts immediately and the application finishes when processing is done. The scheduler is disabled in offline mode.
```
scwfparam --offline -I vallorcine.mseed \
          --inventory-db vallorcine_inv.xml \
          --ep vallorcine.xml -E "Vallorcine.2005.09.08" \
          --lo-filter 0.1 --hi-filter 0
```

Running for a given event with scheduling enabled. Only the given event will be processed.

scwfparam -I arclink://localhost:18001 -E gfz2011oeej \
          -d mysql://sysop:sysop@localhost/seiscomp3

For running in real-time it is enough to add the module to the client list of the trunk package in seiscomp config.

Running with remote Arclink server

To use a remote Arclink server it is enough to configure the record stream with -I:

scwfparam --offline -I vallorcine.mseed \
          --inventory-db vallorcine_inv.xml \
          --ep vallorcine.xml -E "Vallorcine.2005.09.08" \
          -I "arclink://arclink.ethz.ch:18002"

Note that the default acquisition timeout of 30 seconds might not be enough to get all the requested data. If necessary, increase the value with parameter wfparam.acquisition.initialTimeout. This can also be reached on command line:

scwfparam --offline -I vallorcine.mseed \
          --inventory-db vallorcine_inv.xml \
          --ep vallorcine.xml -E "Vallorcine.2005.09.08" \
          -I "arclink://arclink.ethz.ch:18002" \
          --wfparam.acquisition.initialTimeout=300

Running with remote Seedlink server

To use a remote Seedlink server it is enough to configure the record stream with -I:

scwfparam --offline -I vallorcine.mseed \
          --inventory-db vallorcine_inv.xml \
          --ep vallorcine.xml -E "Vallorcine.2005.09.08" \
          -I "slink://geofon.gfz-potsdam.de:18000"

wfparam.pd.hiFreq¶

Type: double

Specifies the frequency of the 2nd stage lo-pass filter. If this parameter is equal to 0 the lo-pass filter is not used. If suffix “fNyquist” is used then the value is multiplied by the Nyquist frequency of the data to get the final corner frequency of the filter. Default is 0.

wfparam.acquisition.initialTimeout¶

Type: int

Unit: s

Specifies the initial acquisition timeout. If the acquisition source (e.g. Arclink) does not respond within this threshold with waveforms, the request is discarded. Default is 30.

wfparam.acquisition.runningTimeout¶

Type: int

Unit: s

Specifies the acquisition timeout when waveforms are being transfered. If no new waveforms arrive within this threshold, the request is aborted. This is important if a Seedlink connection is configured which can block the application for a very long time if at least one requested channel has no data. Seedlink does not finished the request until all data has been sent. When data will arrive for a particular channel is not known. Default is 2.

wfparam.output.messaging¶

Type: boolean

Enables messaging output which creates objects of the StrongMotionParameters data model extension (defined by SED) and sends them to scmaster. In order to save the objects to the database, scmaster needs to load the dmsm plugin and the corresponding database schema must be applied. The default message group is AMPLITUDE. To change this group redefine connection.primaryGroup. Default is false.

wfparam.output.shortEventID¶

Type: boolean

Uses short event ids when an event output directory needs to be created. The default pattern is [eventtime]_[mag]_[lat]_[lon]_[updatetime]. The short format just contains the first part, namely [eventtime] in the format YEARmmddHHMMSS. Default is false.

Specifies the spectra output path. This parameter is only used if wfparam.output.spectra.enable is true. Default is @LOGDIR@/shakemaps/spectra.

wfparam.output.spectra.withEventDirectory¶

Type: boolean

Enables/disables the creation of an event directory (named with eventID) when storing the spectra. This parameter is only used if wfparam.output.spectra.enable is true. Default is false.

wfparam.output.shakeMap.enable¶

Type: boolean

Enables/disables ShakeMap XML output. Default is true.

wfparam.output.shakeMap.path¶

Type: string

Specifies the ShakeMap XML output path. This is only used if wfparam.output.shakeMap.enable is set to true. Default is @LOGDIR@/shakemaps.

wfparam.output.shakeMap.script¶

Type: string

Specifies the path to a script that is called whenever a new ShakeMap XML is available. The script is called with 3 parameters: EventID, modified ShakeMap eventID, path to event directory (where input/event.xml and input/event_dat.xml lives). The event files are not deleted by the application. The ownership goes to the called script.

wfparam.output.shakeMap.synchronous¶

Type: boolean

Enables/disables synchronous or asynchronous script calls. If enabled, be careful to not spend too much time in the script. The application is blocked while the script is running. Default is true.

wfparam.output.shakeMap.maximumOfHorizontals¶

Type: boolean

If enabled the maximum PGV, PGA, PSA03, PSA10 and PSA30 of both horizontal components is used in the final output. Otherwise each component is saved. Default is false.

wfparam.output.shakeMap.SC3EventID¶

Type: boolean

Uses the SeisComP3 event publicID as id attribute of the earthquake tag, a generated ShakeMapID otherwise. Default is false.

wfparam.output.shakeMap.regionName¶

Type: boolean

Uses the event region name (if available) for the locstring attribute, the publicID, lat, lon otherwise. Default is false.

wfparam.output.shakeMap.encoding¶

Type: string

The XML encoding string written to the Shakemap XML file. Default is UTF-8.

Bindings¶

Configuration¶

amplitudes.PGAV.saturationThreshold¶

Type: string

Defines the saturation threshold for the optional saturation check. By default the saturation check is configured for all stations as module parameter. This parameters overrides the threshold per station.

This value can either be an absolute value such as “100000” or a relative value (optionally in percent) with respect to the number of effective bits, e.g. “0.8@23” or “80%@23”. The first version uses 1**23 * 0.8 whereas the latter uses 1**23 * 80/100.

The special value “false” explicitly disables the check.
