# scwfparam

Waveform parametrization module.

## Description

scwfparam is a SeisComP 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:

1. Process creation (new event or updated event seen the first time)

2. 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.

### Event XML

## Examples

1. 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

2. 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/seiscomp

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

4. 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

5. 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"

  Analogue to wfparam.magnitudeTimeWindowTable but instead giving a time window, the distance in km is specified. Example: "3:400, 4:450, 5:500"

wfparam.saturationThreshold

  Default: `80`

  Type: double

  Unit: %

  Relative saturation threshold in percent. If the absolute raw amplitude exceeds X% of 2**23 counts the station will be excluded from processing. This assumes a 24bit datalogger.

  Type: list:string

  Magnitude dependent filter table. The format is "mag1:fmin1;fmax1, mag2:fmin2;fmax2, mag3:fmin3;fmax3". If a magnitude falls between two configured magnitudes the filter of the lower magnitude is then used. No interpolation takes place. Magnitude outside the configured range are clipped to the lowest/highest value.

Note

wfparam.streams.* Defines the white- and blacklist of data streams to be used. The rules to decide if a stream is used or not are the following: ** 1. if whitelist is not empty and the stream is not on the whitelist, don’t use it, ok otherwise ** 2. if blacklist is not empty and the stream is on the blacklist, don’t use it, ok otherwise ** Both checks are made and combined with AND. Either whitelist or blacklist contains a list of patterns (wildcard allowed as * and ?), eg GE..*.*, , GE.MORC..BH? Each stream id (NET.STA.LOC.CHA) will* be checked against the defined patterns.

  Type: double

  Specifies the frequency of the 1st stage hi-pass filter. If this parameter is equal to 0 the hi-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.

wfparam.filter.hiFreq

  Default: `40`

  Type: double

  Specifies the frequency of the 1st 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.

Note

wfparam.pd.* Parameters of the post-deconvolution filter applied in the frequency domain.

wfparam.pd.order

  Default: `4`

  Type: int

  Specifies the order of the 2nd stage filter.

wfparam.pd.loFreq

  Default: `0`

  Type: double

  Specifies the frequency of the 2nd stage hi-pass filter. If this parameter is equal to 0 the hi-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.

wfparam.pd.hiFreq

  Default: `0`

  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.

wfparam.filtering.padLength

  Default: `-1`

  Type: double

  Unit: s

  The length of the zero padding window in seconds applied on either side of the waveform if non-causal filters are activated. If negative, it is computed following Boore (2005) as 1.5*order/corner_freq and applied half at the beginning and half at the end of the waveform.

  Type: int

  Unit: s

  Specifies the interval in seconds to check/start scheduled operations.

wfparam.cron.eventMaxIdleTime

  Default: `3600`

  Type: int

wfparam.cron.logging

  Default: `true`

  Type: boolean

  Enables/disables updating of a cron log file. This file will be created at ~/.seiscomp/log/[appname].sched and contains information about the scheduled events and the processing queue. The file is updated each n seconds, where n = wfparam.cron.wakeupInterval.

wfparam.cron.updateDelay

  Default: `60`

  Type: int

  Specifies the delay in seconds to delay processing if a new authoritative origin arrives for an event.

wfparam.cron.delayTimes

  Type: list:int

  Specifies a list of delay times in seconds relative to event time to trigger the processing. When the first origin of an event arrives this list is used to construct the crontab for this event. Example: "60, 120, 300, 3600"

wfparam.acquisition.initialTimeout

  Default: `30`

  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.

wfparam.acquisition.runningTimeout

  Default: `2`

  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.

wfparam.output.messaging

  Default: `false`

  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.

wfparam.output.shortEventID

  Default: `false`

  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.

wfparam.output.waveforms.enable

  Enables/disables the output of spectra (psa, drs). The output format is a simple ASCII file where the first column is the period and the second column the corresponding value.

wfparam.output.spectra.path

  Default: `@LOGDIR@/shakemaps/spectra`

  Type: string

  Specifies the spectra output path. This parameter is only used if wfparam.output.spectra.enable is true.

wfparam.output.spectra.withEventDirectory

  Default: `false`

  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.

wfparam.output.shakeMap.enable

  Default: `true`

  Type: boolean

  Enables/disables ShakeMap XML output.

wfparam.output.shakeMap.pgm

  Default: `pga, pgv, psa03, psa10, psa30`

  Type: list:string

  Define a list of pg values to be forwarded to ShakeMap in version 4 or later. The period xx in psa must be in the list of naturalPeriods and must not exceed 9.9s.

wfparam.output.shakeMap.path

  Default: `@LOGDIR@/shakemaps`

  Type: string

  Specifies the ShakeMap XML output path. This is only used if wfparam.output.shakeMap.enable is set to true.

wfparam.output.shakeMap.script

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

  Default: `true`

  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.

wfparam.output.shakeMap.maximumOfHorizontals

  Default: `false`

  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.

wfparam.output.shakeMap.SC3EventID

  Default: `false`

  Type: boolean

  Uses the SeisComP event publicID as id attribute of the earthquake tag, a generated ShakeMapID otherwise.

wfparam.output.shakeMap.regionName

  Default: `false`

  Type: boolean

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

wfparam.output.shakeMap.encoding

  Default: `UTF-8`

  Type: string

  The XML encoding string written to the Shakemap XML file.

wfparam.output.shakeMap.version

  Default: `3`

  Type: int

  The target version of the Shakemap input files.

## Bindings Parameters

commtype

  Default: `DIG`

  Type: string

  Defines the communication type of the station which is forwarded without modification to the Shakemap input file in version 4 or greater. Reference: https://usgs.github.io/shakemap/manual4_0/sg_input_formats.html.

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.

## Command-Line Options

### Generic

-h, --help

  Show help message.

-V, --version

  Show version information.

--config-file arg

  Use alternative configuration file. When this option is used the loading of all stages is disabled. Only the given configuration file is parsed and used. To use another name for the configuration create a symbolic link of the application or copy it. Example: scautopick -> scautopick2.

--plugins arg

  Load given plugins.

-D, --daemon

  Run as daemon. This means the application will fork itself and doesn’t need to be started with &.

--auto-shutdown arg

  Enable/disable self-shutdown because a master module shutdown. This only works when messaging is enabled and the master module sends a shutdown message (enabled with --start-stop-msg for the master module).

--shutdown-master-module arg

  Set the name of the master-module used for auto-shutdown. This is the application name of the module actually started. If symlinks are used, then it is the name of the symlinked application.

--shutdown-master-username arg

  Set the name of the master-username of the messaging used for auto-shutdown. If "shutdown-master-module" is given as well, this parameter is ignored.

-x, --expiry hours

  Time span in hours after which objects expire

-E, --event-id arg

  EventID to calculate amplitudes for

--ep arg

  EventParameters (XML) to load

### Verbosity

--verbosity arg

  Verbosity level [0..4]. 0:quiet, 1:error, 2:warning, 3:info, 4:debug.

-v, --v

  Increase verbosity level (may be repeated, eg. -vv).

-q, --quiet

  Quiet mode: no logging output.

--component arg

  Limit the logging to a certain component. This option can be given more than once.

-s, --syslog

  Use syslog logging backend. The output usually goes to /var/lib/messages.

-l, --lockfile arg

  Path to lock file.

--console arg

  Send log output to stdout.

--debug

  Execute in debug mode. Equivalent to --verbosity=4 --console=1 .

--log-file arg

  Use alternative log file.

### Messaging

-u, --user arg

  Overrides configuration parameter `connection.username`.

-H, --host arg

  Overrides configuration parameter `connection.server`.

-t, --timeout arg

  Overrides configuration parameter `connection.timeout`.

-g, --primary-group arg

  Overrides configuration parameter `connection.primaryGroup`.

-S, --subscribe-group arg

  A group to subscribe to. This option can be given more than once.

--content-type arg

  Overrides configuration parameter `connection.contentType`.

--start-stop-msg arg

  Set sending of a start and a stop message.

--test

  Test mode, no messages are sent

### Database

--db-driver-list

  List all supported database drivers.

-d, --database arg

  The database connection string, format: service://user:pwd@host/database. "service" is the name of the database driver which can be queried with "--db-driver-list".

--config-module arg

  The config module to use.

--inventory-db arg

  Load the inventory from the given database or file, format: [service://]location .

--db-disable

  Do not use the database at all

### Records

--record-driver-list

  List all supported record stream drivers.

-I, --record-url arg

  The recordstream source URL, format: [service://]location[#type]. "service" is the name of the recordstream driver which can be queried with "--record-driver-list". If "service" is not given, "file://" is used.

--record-file arg

  Specify a file as record source.

--record-type arg

  Specify a type for the records being read.

### Mode

--order arg

  Filter order

--lo-filter freq

  High-pass filter frequency

--hi-filter freq

  Low-pass filter frequency

--sc-order arg

  Sensitivity correction filter order

--sc-lo-filter freq

  Sensitivity correction high-pass filter frequency

--sc-hi-filter freq

  Sensitivity correction low-pass filter frequency

--offline

  Do not connect to the messaging and and disable the database in combination with --inventory-db and --ep

--force

  Force event processing even if a journal entry exists that processing has completed

--force-shakemap

  Force ShakeMap script to be run even if no station has contributed data

--dump-config
