Getting Started with Jiggle: Database Connection, Events in Catalog and Map

Let's run Jiggle from the command line, with input parameters from jiggle_waves.props:

$ ./run_jiggle.sh ../prop/jiggle_waves.props


The "Event Selection Properties" dialog box (below) appears. The "User" input properties file status should be "exists: true". It is ok if the "Default" properties files has "exists: false". Click the OK button.


Next, the "Database Connection Info" dialog box (below) appears. These values are pre-populated by the properties files. They are required to connect to the Oracle or Postgres database containing earthquake information through the JDBC API. SCSN-specific inputs are shown below: the name of the server hosting the database is blanchard.gps.caltech.edu, and the database name is archdbe. The JDBC connection is through a 4-digit port number, which should replace the PORT placeholder. Database credentials would be indicated next to "User:", where the username would replace the USERNAME placeholder, and the password next to "Password:". Click the OK button to proceed.


Jiggle connects to the database, retrieves earthquake event data from it, and displays the catalog from the last 72 hours in tabular form (screenshot below). See the Catalog View section for more detail about the content of the earthquake catalog.

  • No events have been loaded yet, so many of the icons in the top row of the GUI, as well as the “Event” in the menu bar, are grayed out and inaccessible. In the Status bar (lower right corner), the event-specific statistics all have zero values.
    • The third entry in the Status bar shows the database name @ server name (e.g. archdbe@blanchard).
  • The number of events (rows) displayed is shown in the bottom left corner ("Table has 157 rows").
  • Events in the "green" rows have been inspected and finalized by human analysts. These have a value of "F" in the "ST" column.
  • Events in the "yellow" rows have been accepted for further review by analysts. These have a value of "H" in the "ST" column.
  • Events in the "pink" rows are automatic solutions that have not yet been checked by analysts. These have a value of "A" in the "ST" column. Figure


Clicking on the Map icon Image in the catalog view above will open a new window with locations of catalog events from the database (cyan circles sized by magnitude) in map view (below). The map also displays locations of seismic stations (light green triangles), cities (red squares with green lettering), historic earthquakes (red stars), quarries (purple X's), and faults (orange lines), which are are each a separate map layer that can be toggled on and off. Pan and zoom in/out are possible. See the Map Layer View section for more detail about viewing catalog events on the map.

Jiggle GUI 5 Tab Views

In the screenshot below, the Jiggle GUI has 5 main Tab views, from left to right, which can be accessed by either clicking on the appropriate Tab view icon (below) or pressing a key (all keys below are capital letters, so the Shift key must be held down):

  1. Location View  locate, or press 'L'
  2. Magnitude View  mini-m-blk-script, or press 'M'
  3. Message View  file, or press 'T'
  4. Catalog View  mini-zagscroll, or press 'C'
  5. Waveform View  sinewave2, or press 'W'

Figure

The Jiggle GUI is currently in the Catalog View (the mini-zagscroll icon tab has a gray background). The icons in the "Catalog view actions" red box under the "Tab views" icons are specific to the Catalog View, and are not found in the other 4 tab views. See the Catalog View section for a full description of the possible "Catalog view actions"; some of these actions apply only to the selected catalog event (white row with event ID 38466968 in the screenshot).

Some Jiggle GUI elements are seen in all 5 tab views. The GUI has a "Menu bar" (File, View, ... , Help in the red box) at the top to take various actions, a toolbar row of icons just under the menu bar (starting with the "Map" red box), and a "Status bar" in the red box at the bottom right with database information.

Summary of Typical Post-Processing Workflow: 6 Steps

This section of the guide summarizes the typical post-processing workflow for improving a single event solution within Jiggle. This section is simply a general overview; please refer to the individual pages on each Jiggle tab view for a thorough reference.

  1. Load single event from database (Catalog View)
  2. Modify picks and amplitudes on event waveform channels (Waveform View)
  3. Recalculate event location and origin time (Location View)
  4. Recalculate event magnitude (Magnitude View)
  5. Save and finalize improved earthquake solution to database
  6. Preview and load next event to process

Step 1: Load single event from database (Catalog View)

In the screenshot in the Jiggle GUI 5 Tab Views section, many of the icons in the top toolbar row of the GUI, as well as the "Event" in the "Menu bar", are currently grayed out and inaccessible, because an event has not yet been selected and loaded into Jiggle. To activate these icons, we need to select and load a specific event (row in the table) by taking one of the following actions:

  • In Catalog View, double-click on the event row
  • In Catalog View, select the event row (highlighted in white) and click the green arrow  inputarrowsmall  (right-most icon in "Catalog view actions")
  • In Catalog View, select the event row (highlighted in white), right-click to open a popup menu, and click on "Load"
  • In Catalog View, select the event row (highlighted in white) and click on "Menu bar": File → Open Catalog Selection
  • In Map Layer View, double-click on the event location (cyan circle)
  • In "Menu bar": File → Open event by id..., type in 8-digit event ID number (e.g. 37536154)


The screenshot below shows the Jiggle GUI, still in Catalog View, after an earthquake event (with ID 37536154) has been selected and loaded. The event ID 37536154 next to an orange square now appears in the "Selected Solution" box. Information for the loaded event also appears in the title bar. Most of the icons in the top row of the GUI including those in the "Event Editing" box, as well as the "Event" in the "Menu bar", are now accessible. The Status bar (lower right corner) now displays statistics for this event.

Figure


Clicking on the "Gazetteer" icon   Figure   in the top toolbar displays the distance and direction from the loaded event (ID 37536154) to nearby cities and other locations of interest (screenshot below).


In the Map Layer View (screenshot below), a pink arrow points to the location of the loaded event, and the information for the loaded event with ID 37536154 appears in the title bar.

Figure

Step 2: Modify picks and amplitudes on event waveform channels (Waveform View)

The Waveform View can then be selected to view waveforms for the loaded earthquake event (ID 37536154, seen in the "Selected Solution" box). Notice that the Waveform View sinewave2 icon now is highlighted with a blue background within the "Tab views " red box. The "Status bar" (red box, bottom right) shows statistics for this loaded event: 3738 channels at 660 stations, 30 arrival time picks, 62 peak amplitudes (amps), and 0 coda estimates.

Figure

Various categories of tools available only in the Waveform View are grouped into red boxes within the screenshot:

  • Time zoom
  • Pick tools
  • Amplitude zoom
  • Filter single channel
  • Triaxial display
  • Manual time zoom
  • Waveform scroll and selection
  • Filter all waveforms

Icons in the main toolbar for relevant actions within the Waveform View are also grouped into red boxes within the screenshot:

  • New event
  • Waveform views
  • Auto-picker
  • Show only certain waveforms
  • Scope Mode

The channels are read in from a cache file for faster loading, which is refreshed every time Jiggle starts up (click the YES button in the screenshot below to reload the channel list). (TODO check for accuracy)

The "All event waveforms" bottom window in the Waveform View screenshot displays the 3-minute-duration event waveforms for all 3738 channels at 660 seismic stations, ordered by increasing distance from the event location to each station. To view waveforms from all of the channels, use the scrollbar or the tools in the "Waveform scroll and selection" red box. Waveforms from some channels may not always appear due to gaps in the data. The event waveforms can be read from a database containing either triggered or continuous waveforms.

Each waveform is named with the ${NETWORK}.${STATION}.${CHANNEL} convention, e.g. for CI.TUQ.HHZ, the network code is CI, the station name is TUQ, and the channel name is HHZ. See the Station Naming Convention SCSN Wiki Page or SCEDC SEED Channel Descriptions for more details.

A single station usually has multiple channels, which can record the ground motion from the earthquake in three different directions:

  • HHZ: vertical
  • HHN: horizontal, north-south
  • HHE: horizontal, east-west

In addition, a single station usually has differences in sampling rate, frequency range, or gain, which are reflected in different colors for the waveforms in the Waveform View.

  • HHZ, HHN, HHE: high sample-rate broadband (black)
  • HNZ, HNN, HNE: high sample-rate accelerometer (olive)
  • BHZ, BHN, BHE: low sample-rate broadband (cyan)
  • EHZ: extremely short period (blue)

The "Single channel event waveform" top window in Waveform View shows a waveform from one channel at a time. In the "All event waveforms" window, the selected channel CI.TUQ.HHZ is shown as a light blue row, and the yellow box indicates the section of the waveform displayed in the " Single channel event waveform" window. The tools in the "Time zoom" and "Manual time zoom" red boxes allow zooming in and out along the time axis for this channel, while the tools in the "Amplitude zoom red box allow zooming in and out in the amplitude dimension; the yellow box changes shape accordingly.

The Waveform View also provides an alternative triaxial view (TODO place link), which displays 3 channels of event waveforms (vertical, north-south, east-west) at a time, all from the same station. In the "All event waveforms" window, this can be accomplished with the "Waveform views" tools (red box in the main toolbar), but requires several setup steps (TODO place link). In the "Single channel event waveform" window, the "Triaxial display" mini-triaxialgray tool overlays these 3 channels on top of each other.

Users can apply different types of filters (e.g. bandpass, highpass, lowpass) to the event waveforms. The "Filter all waveforms" filter_yellow tool in the bottom right corner applies the selected filter to all channels in the "All event waveforms" window. The "Filter single channel" filter_yellow tool filters only the data in the "Single channel event waveform" window.

Within the Waveform View, users can modify arrival time picks (e.g. iPc0, eS 2), and peak amplitude estimates, often called "amps" (small orange triangles on HHN and HHE channels), to improve their quality. Changing the picks will change the earthquake origin (location and origin time), and changing the amps will change the earthquake magnitude.

  • These picks and amps, initially obtained from the AQMS real-time (RT) system, are loaded from the database. The "Status bar" (bottom right) shows a total of 30 arrival picks and 62 amps.
  • The "Show only certain waveforms" tools (red box, top right) displays only the waveforms with an existing pick (P) or amp (A) in the "All event waveforms" window (TODO: explain C).
  • Green vertical bars in the "Single channel event waveform" and "All event waveforms" windows indicate approximate expected P (earlier) and S (later) arrival times at each station. If the actual phase picks deviate significantly from the green bars, then the event is mislocated.
  • The "Auto-picker" autopick in the tool bar can be used to automatically pick P and S arrival times. Parameters for the Auto-picker are in the pickEW.props properties file.
  • Users can also manually pick arrivals within the "Single channel event waveform" window using the "Pick tools", aided by the zoom features. Users can add new manual picks at channels on stations without picks, and delete poor quality automatic picks.
  • Picking is usually done on channels with higher sample rate; P phases are usually picked on the vertical channel and S phases on the horizontal channels.
  • Picking is done on stations out to a distance of about 120 km; further stations are probably too noisy to reliably determine picks.
  • Amps determined by the RT system can be rejected if manual inspection shows that they are incorrect.
  • Right-click in either the "All event waveforms" or "Single channel event waveform" window to bring up a menu with many options.

Sometimes the "All event waveforms" window might show two (or more) earthquake waveforms, which happened close together in time, for a single catalog event. In this case, one can use the "New event" new-blue tool to clone the waveforms from the catalog event into a new event (TODO link). Then users can pick arrivals and estimate amplitudes on the second event waveform (that was originally not in the catalog), determine its origin and magnitude, and save it to the database.

In addition to viewing event waveform data, users can also view continuous seismic waveform data within Jiggle by turning on Scope mode oscilloscope.

Step 3: Recalculate event location and origin time (Location View)

The Location View can be selected to view the origin (location and origin time) information for the loaded earthquake event (with ID 37536154, "Selected Solution" box). Notice that the Location View locate icon now is highlighted with a gray background within the "Tab views" red box.

Figure

The event origin is calculated using the HYPOINVERSE earthquake location program. At the SCSN, HYPOINVERSE runs on a separate server, called the "solution server" or "solserver". HYPOINVERSE uses the P and S arrival time picks at different stations, along with a 1D flat-layer velocity model, to solve for the best-fit event origin (latitude, longitude, depth, origin time). The SCSN uses the HK_SOCAL velocity model (Hadley and Kanamori, 1977), available as Table 5 in (Hutton et al., 2010).

  • Initially, users see the event origin calculated by HYPOINVERSE using picks from the RT AQMS system as input.
  • The yellow window with "Event origin solutions" contains the event origin (location and origin time) and other parameters output from running HYPOINVERSE.
  • The "Pick information" window shows the picks on each channel that were used to calculate the event origin.
  • Clicking the "Calculate Location" bullseye tool runs HYPOINVERSE again, this time using improved (automatic and/or manual) pick estimates from the Waveform View for this event.

Step 4: Recalculate event magnitude (Magnitude View)

The Magnitude View can be selected to view the magnitude information for the loaded earthquake event (with ID 37536154, "Selected Solution" box). Notice that the Magnitude View mini-m icon now is highlighted with a gray background within the "Tab views" red box.

Figure

Magnitudes depend on peak amplitude estimates that were initially determined by AQMS RT, but can be modified in the Waveform View (small orange triangles) for the loaded event. Magnitudes also depend indirectly on the event location, since the distance from the event to each station with an amplitude estimate is used to calibrate the magnitude; therefore, after recalculating the event location with HYPOINVERSE, magnitude should also be updated.

There are different algorithms for calculating the magnitude of an earthquake in Jiggle, which can be done with the "Calculate Magnitude" mini-m pm-script tools:

  • ML: Local magnitude
    • Generally used as "prefmag" (preferred magnitude) for small (M < 3) local earthquakes?
    • Calculated with the peak amplitude on the horizontal (north-south, east-west) channels, and amplitudes are calibrated to magnitude by using the distance from event to each station.
  • Md: Duration magnitude
    • TODO: when/how used? Generally used for small earthquakes.
    • Calculated using the time duration of the coda after the S-wave.

Jiggle currently does not have functionality to calculate the following magnitude types, which are commonly used for larger (M > 6) earthquakes. These types may be visible in the database, as they might be imported from AQMS RT or from other seismic networks.

  • Me: Energy magnitude
    • First available magnitude for large (M > 6) earthquakes, before Mw
  • Mw: Moment magnitude
    • Most reliable magnitude estimate for large (M > 6) earthquakes
    • Reflects dimensions of the earthquake, without saturating for the largest earthquakes.
    • Calculated with a moment tensor fit.
  • Mh: Human-edited magnitude
    • This magnitude type can be set in DRP
    • Usually seen for exotic events (e.g. chemical blast)
    • Sometimes saved as "Intermediate" processing state events, flagged for further analysis later
  • Mun: Unknown magnitude
    • Usually seen for regional or teleseismic earthquakes outside network boundaries, with catalog solution imported from other networks

The "Magnitude type views" tabs, available only within the Magnitude View, allow toggling between these different magnitude estimates. In the screenshot above, only ML is available for event ID 37536154, but additional entries for other magnitude types (e.g. Md, Me) are possible. One of these magnitude types should be set as the preferred type, which will then appear as "EVENT PREFERRED" in the top left corner within the selected Magnitude type view.

In each Magnitude type view, the yellow window with "Event magnitude solution" contains the event magnitude and other relevant parameters, while the "Amp information" window shows the peak amplitude estimates on each channel that were used to calculate the event magnitude.

Step 5: Save and finalize improved earthquake solution to database

At this point, the user has manually inspected picks and amps on event waveforms, and calculated an improved event origin (location and origin time) and magnitude within Jiggle. In order to save this improved solution to the database, click on the "Save event" save tool.

In the Catalog View (screenshot below), the saved event appears as an orange row, the "ST" column has the letter "I" indicating that the intermediate solution was saved, the "SRC" column says "Jiggle" indicating that the solution was modified within Jiggle, and the "OWHO" column has the string "cyoon" indicating the name of the user who changed the solution.

Figure

To permanently save the improved solution to the database, without allowing any further edits, the user can finalize the event solution within the database by clicking on the "Finalize event" finalize tool.

In the Catalog View (screenshot below), the finalized event appears as a green row, the "ST" column has the letter "F" indicating that the solution was finalized, the "SRC" column says "Jiggle" indicating that the solution was modified within Jiggle, and the "OWHO" column has the string "cyoon" indicating the name of the user who changed the solution.

Figure

The Database Actions section has more information about how to save save or finalize finalize an event. This section also describes how to delete an event dynamite that is not an earthquake, or to clone a new event new-blue if an existing catalog event window has more than one earthquake waveform.

Step 6: Preview and load next event to process

At this time, the user can select and load the next event to process in Jiggle. The user can choose to load the next event by following instructions in Step 1, then repeat Steps 2-5.

Alternatively, the user can preview the next event to load and process in Jiggle. In the screenshot below, the current loaded event has ID 37536154 (red boxes, pink arrow with red text on map). Users can click on another location in the map (white arrow) to display the ID 37536154 (blue text and boxes) of the next event to potentially select, which can be seen in the bottom status bar on the map, and the row within the Catalog View highlighted in red on white background. The user can then repeat Steps 1-5 on the previewed event.

Figure

Another way to select the next event to load and process in Jiggle is to choose the next event (next row down) in the table under Catalog View, clicking on the "Next Event" forward icon, then repeat Steps 2-5 on the newly loaded event. The user can choose to sort the events within the catalog table in a different order, according to different columns (more details in Catalog View).

The user can also choose to close the current event ("Menu bar": File → Close Event), which would return to the status in Jiggle GUI 5 Tab Views where no events are loaded.

Message View

The Message View within Jiggle is used to output various information in text format. When an event is first loaded, nothing appears in the Message View. However, when HYPOINVERSE is run with the "Calculate Location" bullseye tool, the Message view displays the output of the HYPOINVERSE program. The Message View also allows users to view the properties file contents (notice that the
Message View file icon now is highlighted with a blue background within the "Tab views" red box), and other information accessible through the "Dump" menu in the "Menu bar".

SplitPane Frame Layout

It is possible to change the frame layout in Jiggle so that the Catalog View, Map Layer View, and Waveform View can be viewed at the same time within one window (screenshot below). This is called the "SplitPane" frame layout.

Figure

To get the SplitPane layout, select the following in the "Menu bar":

  • "View → Waveforms... → Waveforms in SplitPane" to view the waveforms on the same screen as the catalog. Notice that the Waveform View sinewave2 tab icon is no longer there.
  • Then select "View → Map... → Split with Catalog" to view the map within the same window as the catalog (and waveforms).
  • The "View" menu also offers the option of either a vertical or horizontal split of the catalog window with the map, and with the waveform window.
  • Use the mouse to resize the different frames.

To go back to the default frame layout, select the following in the "Menu bar":

  • "View → Waveforms... → Waveforms in TabPane" to create a separate tab for the Waveform View sinewave2.
  • Then select "View → Map... → Separate Window" to move the map back to its own window.

For every Jiggle run, a log file is written to a logs/ subdirectory in the properties files directory, named with the date and time that Jiggle was started: jiggle_YYYY-MM-DD(HHMMSS).log.

These log files facilitate debugging for the Jiggle developer, but can take up extra disk space. Various "debug" and "verbose" flags in the properties files can be set to increase the level of detailed logging (TODO list these flags)

On starting Jiggle, a dialog box pops up with the option to remove log files older than 14 days (screenshot below).

Exit Jiggle

To exit Jiggle, click "File → Exit" on the "Menu bar", and a dialog box asks to confirm if the user really wants to exit (screenshot below).
