Graphical User Interface¶

../_images/toast_ui.png — TOAST user interface¶

Map perspective shows maximum wave height, arrival lines and warning levels.¶

Traces perspective — Real-time waveforms provide instantaneous sea-level information.¶

Arrivals perspective shows tsunami metrics computed on simulations and manual picks.¶

Forecast perspective — Forecast zones perspective shows the local threat levels in tabular form.¶

Overview¶

The TOAST user interface consists of one large main panel with several tabs and three smaller panels.

../_images/toast_ui_panels.png — TOAST user interface panels¶

The tabs in the main panel offer following perspectives:

Map perspective
Traces perspective
Arrivals perspective
Displacements perspective
Forecast Zones perspective
Impact Reports perspective
Live Tabs

The first six are always present. The others are configurable Live Tabs which are used to create, view and disseminate bulletins. They are set up as described in: Live Tabs configuration.

On the right side (by default), there are three smaller panels:

Map Layers
Database
Wave Propagation

Hint

The various perspective tabs in the main panel and the Map Layers-, Database- and Wave Propagation panels can be undocked and moved to an other position or even different screen using drag and drop with the left mouse button. Upon closing, the perspectives get reinserted in the main window. The three small panels can be switched on or off using Menu ‣ View.

Incidents are the primary objects in TOAST. They can contain a SeisComP event reference and zero or multiple simulations. In case simulations are present, they can be set active using the database panel. In the Map layers panel they can be switched on and off for display in the Map perspective and the Wave Propagation panel.

SeisComP events are received through the messaging system and - depending on configuration settings - can automatically trigger the creation of new incidents and simulations. New incidents and simulations can also be generated manually by user interaction. See also: Import events and create incidents in TOAST and Simulations.

The Map perspective shows the location of the tide gauges as well as information related to active incidents and simulations, like maximum wave height and forecast zones warning levels.

Real-time data from the configured tide gauge stations is shown in the Traces perspective.

In the Arrivals perspective, tsunami metrics at the tide gauges for real data as well as simulations are listed. The Waveform picker is used to manually pick tsunami arrivals, amplitudes and periods on observed tide gauge time series (black line). Traces corresponding to active simulations are shown in the same color throughout all perspectives. Observed and simulated data can be compared here.

The Forecast Zones perspective is used to assess the warning levels at the defined coastal sections.

Test mode¶

TOAST has a test mode which can be toggled on and off using CTRL+T or by: Menu ‣ Extras ‣ Toggle test mode. If enabled, a thick orange bar is drawn around the TOAST user interface. In test mode, bulletins can not be disseminated, unless their configured templates explicitly allow it.

Hotkeys¶

Following hotkeys are available in all perspectives.

Main panel¶

Incident Summary¶

The top of the main panel contains the Incident Summary, which shows some information on the active Incident, namely:

Origin time
Time ago
Region
Focal mechanism (if available)
Preferred magnitude
ID

See Database panel and Import events and create incidents in TOAST on how to select or import incidents.

../_images/incident_summary.png — Incident Summary¶

If the lock button on the right side is pushed, the current incident remains active if the creation of new incidents is triggered by the messaging system.

Map perspective¶

The Map tab presents an overview of the current situation. It displays the tide gauge stations (either clustered or not), the configured tectonic faults and the location of the active incident. By right mouse click on the map several options can be configured.

../_images/perspective_map1.png — *Map* perspective¶

If one or more simulations are active, the map can also display results related to the simulation(s), like arrival times, predicted wave height, warning levels for the forecast zones and others. Which features are to be shown can be selected in the Map Layers panel.

The handling of the Map perspective is similar as in SeisComP. For instance, to locate a station on the map, press CTRL+F, enter or select a station ID from the list and click the find button. With CTRL+mouse click distances and directions can be measured. By clicking on a station or a forecast zone, it is selected in the Arrivals- or the Forecast Zones perspective as well. With SPACE+mouse click the tables are additionally scrolled to the selection. This works as well the other way around: SPACE+mouse click in the Arrivals or Forecast Zones perspective centers the object on the map.

Simulation player¶

Upon moving the mouse to the lower edge of the map, the simulation player bar is shown, see figure TOAST simulation player. For instance, if SSH max is selected in the Map Layers panel, it can be used to illustrate the propagation of the tsunami wave for active simulations in real- or accelerated time.

../_images/perspective_player.png — TOAST simulation player¶

The triangle icon starts the playback, the watch icon jumps to current time before starting playback. Using the settings icon on the right you can select among other things whether to display absolute time (that is, simulation time corresponding to player position) in the lower left of the map. You can also display relative time either with respect to origin time or current time.

Hotkeys¶

Following additional hotkeys are available in Map perspective.

*Map* perspective hotkeys¶
Action	Description
CTRL+F	Show station search
Arrows	Move map
Mouse wheel	Zoom
Double click	Center map
Pan	Move map
Middle mouse button	Create artificial incident
Mouse click on POI (tide gauge or GNSS station)	Select (also in Arrivals perspective)
Mouse click on forecast zone	Select (also in Forecast Zones perspective)
SPACE+mouse click on POI or zone	Additionally scroll to selection in other perspectives

Traces perspective¶

The Traces tab displays the observed water levels at the tide gauge stations in real time.

../_images/perspective_traces1.png — *Traces* perspective¶

The labels on the left are:

Network code
Station code
Location code
Channel code

In addition to the stream information, the offset (mean) and the difference between the offset and the maximum wave height (amax) are displayed. The number of shown decimals can be configured via the option scheme.precision.traceValues.

The toolbar of the Traces perspective provides the following functions:

Enable computation of spectrograms (color bar symbol)
Show/hide spectrograms (eye symbol) and select mode (long click)
Sort by (Network / Station)
Tide gauge time series filter
Stream selection filter (e.g. VZ.* or *.A*)
Start/stop real time acquisition (green arrow / circle)

A tide gauge time series filter can be applied using the filter drop-down menu. The current filter affects all traces. To change the available filters use: scconfig ‣ Modules ‣ gempa ‣ toast ‣ toast ‣ rttv to set rttv.seaLevel.filters. New filters may be added temporarily by drag and dropping a filter on a trace.

The button with the green arrow starts/stops the data acquisition. A progress indicator is shown if the acquisition is running. To start the acquisition automatically use the configuration option rttv.acquireStreams.

Spectrogram¶

The spectrogram can be seen as a sequence of spectra in time where the frequency axis is vertically arranged and the amplitude is color-coded.

Note

The spectrogram is computed using an Infinite Impulse Response Filter, which allows it to be shown in real-time. Note that due to the low sampling rate of tide gauge data, a delay of about 30 minutes may appear. This is still less than if using a Fast Fourier Transform algorithm.

Enable the computation of the spectrograms using the color bar icon. Activate the display of the spectrograms using the eye icon. The spectrograms can be shown in two different modes which are selected by long mouse click on the eye symbol:

Local scale: Local scale computes the minimum and maximum of each trace and maps the configured gradient color with value 0 to this minimum and gradient color with value 1 to the maximum.
Fixed scale: The configured values (rttv.spectrogram.fixedMinimum and rttv.spectrogram.fixedMaximum) are mapped to rttv.spectrogram.gradient value 0 and 1. The trace minimum/maximum is ignored.

To configure the frequency or period range per stream, create a TOAST binding profile using: scconfig and set spectrogram to either:

periods_log(from, to, ranges, bands) - logarithmic scale
periods(from, to, ranges, bands) - linear scale
freqs_log(from, to, ranges, bands) - logarithmic scale
freqs(from, to, ranges, bands) - linear scale

Then drag and drop the profile to the left either onto a network or station.

Hotkeys¶

Traces perspective supports following hotkeys.

*Traces* perspective hotkeys¶
Action	Description
CTRL+Arrows	Zoom in/out in Time and Amplitude
Buttons	Zoom in/out in Time and Amplitude
Mouse wheel	Scroll through traces
Y / SHIFT+Y	Zoom in/out in Y-scale
< / >	Zoom in/out in X-scale
Pan	Move in time
f	Toggle filter

Arrivals perspective¶

The Arrivals perspective shows tsunami metrics computed on observed data and simulations for tide gauges which fulfill at least one of the following conditions:

At least one simulation is active which affects the tide gauge
A manual pick or an amplitude were set on the observed tide gauge time series using the Waveform picker.

../_images/perspective_arrivals1.png — *Arrivals* perspective¶

For each tide gauge the following information is displayed in tabular form:

Station code
Network code
Location (Longitude Latitude)
Country
Place
Type
Description
Observations
- OTA: Observed time of tsunami arrival
- OTM: Observed time of tsunami maximum wave height
- OMSSH: Observed tsunami maximum wave height (SSH: Sea Surface Height)
- OTP: Observed tsunami period
Simulation results
- Runup
- T1 Time: Time of exceedance of the detection threshold (see also plugin configuration parameters easywave2.T1Threshold and easywave2.T1Absolute)
- T2 Time: Time of first exceedance of the threat threshold
- T3 Time: Time of maximum positive amplitude
- T4 Time: Time of last exceedance of the threat threshold
- Tx Value: Wave height at time Tx

Note

Depending on the simulation backend that is used, Runup and T3 Value might slightly differ. In case of EasyWave for instance, T3 Value is extracted from time series while Runup is output directly. If the difference is large, this could be related to Green’s Law, which, depending on configuration, might be active only on Runup. See EasyWave documentation for more details.

Tide gauges are represented as top level rows which can be expanded by clicking on the plus sign. Then the active simulations affecting the tide gauge are shown. The text color of the simulations coincides with the fill color of the active simulations in the database panel and the other perspectives.

The results for different active simulations are aggregated to obtain results for a tide gauge assuming worst case, that means minimum for arrival times and maximum for wave heights.

The background color of a tide gauge reflects the maximum of OMSSH and Runup. The color scheme is based on the selected SSH color gradient.

A filter can be set to display only a subset of the tide gauges in following way: Click the funnel symbol, select the criterion (e.g. Country), and enter a regular expression (e.g. Indo*).

Upon mouse click on a POI it is also selected in the Map perspective. By SPACE+mouse click, it is additionally centered on the map.

Waveform picker¶

The button Show waveforms at the lower right corner of the Arrivals perspective opens the manual picker and allows picking of tsunami onsets, tsunami amplitudes and tsunami periods on observed tide gauge time series. Values can also be entered manually without using real data for instance for training purposes. If the data source is configured correctly and data are available, the observed tide gauge trace is shown as gray line. If simulations are present and active, corresponding traces are shown in the same color as in the Database panel.

../_images/perspective_arrivals_waveforms.png — Manual picker¶

The toolbar of the manual picker provides the following functions:

Compute spectrograms (color bar symbol)
Show/hide spectrograms (eye symbol)
Sort by (e.g. Distance, Network etc.)
Tide gauge time series filter (Raw, Tsunami), indicated on right side of trace
Stream selection filter (e.g. VZ.T* or *.A*)
Phase picking (arrival time) (blue P)
Amplitude and period picking (blue A, on observed stream and manually)
Submit (red button)
Slot
Mode for showing selected time series (drop-down menu)
Remove offset selector

To pick the tsunami onset click on the P-button (Phase), move the mouse to the position where you want to set it and do a left double-click. Observed time of arrival is labeled OTA.

To pick tsunami amplitudes and periods on observed data, use the A-button (Amplitude). First make sure by clicking on the arrow to the right that Artificial wave height is not selected. Using the mouse with left-click-and-drag on the selected trace on top you can now define a time window which should contain the maximum and the nearest minimum. In case the maximum is clipped, try to estimate the time of the maximum and release the mouse button there. A blue selection appears showing where the amplitude processor looks for the maximum and minimum. Once you release the mouse button, a green selection shows the time window between the found maximum and minimum and which is assumed to be half the tsunami period. Observed time of maximum amplitude is labeled OTM.

If no observed data are available, or if you want to manually enter maximum wave height for a tide gauge, select Artificial wave height by clicking on the selection arrow to the right of the A-button, and proceed as described above. Then you have to enter a value manually for the maximum wave height and half-period corresponds to the selected time window.

To apply arrival times or amplitudes, click on the red submit button and the information is shown in the Arrivals perspective and submitted to the TOAST database.

Picked tsunami arrivals (green vertical line labeled OTA) can be compared to simulated arrivals (small red vertical line). The green window and line labeled OTM indicates the picked observed tsunami period, maximum, and corresponding time. The blue vertical line shows the maximum wave height and corresponding time of the selected simulations (worst-case aggregation).

Note

As later waves are often influenced by the local conditions, for example harbor walls and reflections, it is often useful to focus on the first incoming wave of a simulation.

Displacements perspective¶

The Displacements perspective shows the observed coseismic static displacements (either received automatically by messaging, set manually or imported) as well as computed displacements of the active simulation(s) in tabular form. They correspond to the displacement vectors shown in Map perspective. Both observed and computed displacements are used to compute Displacement residuals to rank simulations.

../_images/perspective_gnss.png — Displacements and active simulations¶

For each GNSS station the following information can be displayed (right click on table header to select columns):

Station code
Network code
Location (Lat/Lon)
Distance to epicenter
Country
Place
Station type
Description
Length: total vector length
H Length: horizontal vector length
East displacement
East channel code
East amplitude ID (if available)
North displacement
North channel code
North amplitude ID (if available)
Up displacement
Up channel code
Up amplitude ID (if available)

Manually set displacement values have a user icon, values received automatically by messaging have a GNSS icon and values imported from an XML file have a file icon. See Import displacement amplitudes and create observed displacements for more information.

Displacements can be removed via Observed displacement ‣ Unset. It is possible to remove all observed displacements at once by right-clicking on an incident and Remove all displacements or via Extras ‣ Remove all incident displacements if an incident is active.

By clicking on the plus symbol of a station, the view is expanded to show the active simulation(s) and the simulation results. The text color of the simulations coincides with the fill color of the active simulations in the database panel and in the other perspectives.

Upon mouse click on a station, it is also selected in the Map perspective. By SPACE+mouse click, it is additionally centered on the map.

Forecast Zones perspective¶

The Forecast Zones perspective shows the forecast zones, the corresponding forecast points (or POI) affected by the active simulation(s) and the simulation results for the zones.

../_images/perspective_forecast_zones.png — *Forecast Zones* perspective with active simulations¶

For each forecast zone the following information is displayed in tabular form:

Name
ID
Place
Province
Country
Geo code
Simulation backend
Runup
T1 Time: Time of exceedance of the detection threshold (see also plugin configuration parameters easywave2.T1Threshold and easywave2.T1Absolute)
T2 Time: Time of first exceedance of the threat threshold
T3 Time: Time of maximum positive amplitude
T4 Time: Time of last exceedance of the threat threshold
Tx Value: Wave height at time Tx

By clicking on the plus symbol of a forecast zone, the view is expanded to show the POI included in the zone. Clicking on the plus sign of a POI expands to show the currently active simulations for this POI.

The text color of the simulations coincides with the fill color of the active simulations in the database panel and the other perspectives.

The background color corresponds to the Runup value (see also: Note on Runup) and the selected forecast zones color gradient.

A filter can be set to display only a subset of the forecast zones in the following way: Click the funnel symbol, select the criterion (e.g. Province), and enter a regular expression (e.g. WEST*).

Upon mouse click on a forecast zone it is also selected in the Map perspective. By SPACE+mouse click it is additionally centered on the map.

Aggregation strategy¶

Note

The aggregation over simulations is done assuming worst-case: that means minimum for arrival time and maximum for wave height. The aggregation over POI runup is done using the selected runupPercentiles profile in the drop-down selector. By default this is Median. The definition of percentiles is according to Python numpy convention. You can add and register additional profiles using scconfig ‣ Modules ‣ gempa ‣ toast ‣ toast.

Manually entering runup for a forecast zone¶

It is possible to enter or override the runup value on forecast zone level manually. This might be useful for instance if there is no simulation available, or if an observed value is received by an external channel like telephone, or for training purposes. To do so, right-click on a forecast zone, and set Threat level ‣ Custom. This can be done both in Map and in Forecast Zones perspective. An icon on the left side of the runup column indicates manually entered values.

Configuration¶

For the setup and configuration of forecast zones, see: Forecast zones configuration.

Impact Reports perspective¶

The Impact Reports perspective can be used to add, edit and remove text-based observations. They are associated with an incident.

../_images/perspective_impact_reports.png — *Impact Reports* perspective with 3 example reports¶

New reports are added by clicking the +-icon, removed by clicking -, and edited via double-click on a report. Report name, Type and Time are mandatory, while Source, Location and Text are optional. Author and ID are generated automatically.

../_images/impact_reports_dialog.png — *Impact Reports* dialog¶

In the bulletin templates, the impact reports can be iterated over similarly to the forecast zones or points of interest. See the example template: impact_reports.txt.example delivered with TOAST.

The default configuration contains the 3 report types “Damage due to tsunami waves”, “Inundation of low-lying coastal areas”, and “Unusual currents and waves”.

Additional report types can be configured using scconfig by adding impactReports profiles and registering them using the configuration parameter impactReports.

Live Tabs¶

Live tabs offer a very powerful way for the creation and dissemination of bulletins based on templates and simulation results. They are displayed as tabs in the main panel.

Configuration¶

For the setup, configuration and use of live tabs and templates, see: Create warning bulletins and other output using templates.

Database panel¶

The database panel has two modes: Incidents mode and Simulations mode. Former is used to import and list currently loaded incidents, while latter shows the simulations (sometimes also called scenarios) available for an incident. The current mode is indicated in the title bar.

Both modes feature an Icons and a Details view which can be activated using the list-icon on the upper right of the panel.

In Incidents mode, by right-clicking on an incident and selecting Open log file… you can open the log file for the respective incident in the system default text editor. To open the incident log viewer click on the Show incident log button in the database panel in Simulations mode or use the Menu or shortcut CTRL+I. For more information see: Incident Log.

Incident mode¶

Import incidents¶

See: Import events and create incidents in TOAST.

Quickfilter¶

In Incidents mode, the upper drop-down menu in the database panel is for filtering incidents and by default allows: Show all, threat and tsunamigenic. Additional filters can be configured using: scconfig ‣ Modules ‣ gempa ‣ toast ‣ toast ‣ filter ‣ incidents. Add an incident filter profile by clicking the green plus button and then configure following parameters:

New filters become available after saving the configuration and restarting TOAST.

Sorting¶

The lower drop down menu is for sorting. Per default the incidents are sorted by origin time. Other possibilities are by Magnitude and by Distance.

Icons view¶

In Icons view, the symbols display following information about the incidents: magnitude, focal mechanism, region and origin time.

If simulations are available for an incident, this is shown by the large right arrow on the right side of an incident. In Details view, the #-column indicates the number of available simulations.

Details view¶

In Incidents mode in Details view (activate by clicking the list-icon on the upper right), the database panel displays following information.

Columns of Database panel in *Incidents mode* in *Details view*¶
Shortcut	Description
M	Preferred magnitude of event
TP	Preferred magnitude type
D	Hypocenter depth
Lat	Latitude
Lon	Longitude
Origin time	Origin time
FM	Preferred focal mechanism
#	Simulation count
Region	Region
Mode	Trigger type (messaging / manual)
# Picks	Pick count
Event ID	From SeisComP if by messaging, from TOAST if manual
ID	Incident ID

Simulation mode¶

Switching from Incidents mode to Simulations mode is done by double clicking an incident, which turns this incident to active and shows simulations available for this incident. Returning to Incidents mode is achieved by clicking the left arrow button or automatically when a new event is sent by the messaging system (unless lock button in Incident Summary is pushed).

Active simulations¶

Note

Simulations can be selected using left mouse click (CTRL+left mouse click to add simulations, SHIFT+left mouse click to select a range of simulations). Note however that simulations become active only after a left mouse double click has been performed! Only active simulations are shown in the Map, Arrivals and Forecast Zones perspectives and are used for the bulletins in the live tabs.

For active simulations, the black part of the beach ball icon on the left is automatically assigned a unique color. If Details view is selected, a colored bar in the magnitude column is shown. The same color is used when showing data related to the corresponding simulation in other perspectives.

Preferred simulation¶

Note

One of the simulations of an incident can be set to preferred, in analogy to SeisComP events, which can have exactly one preferred origin or magnitude etc. The preferred simulation is marked by a star in Icons view and an entry in the corresponding column in Details view.

Incident log¶

Click the Show incident log button to display incident related information, see: Incident Log.

Quickfilter¶

In Simulations mode, the upper drop-down menu in the database panel is for filtering simulations. The default value is Show all. Additional filters can be configured using: scconfig ‣ Modules ‣ gempa ‣ toast ‣ toast ‣ filter ‣ simulations. Add a simulation filter profile by clicking the green plus button and then configure following parameters:

Possible filter settings for simulations¶
Parameter	Description	Default	Example
simulation	Simulation backend	Empty (show all)	EasyWave2
sortColumn	See Details view for possible values	M	Residual
descendingOrder	Descending or ascending	Descending	Ascending
maxNumberOfSims	Limit number of shown simulations	-1 (show all)	4
calculationDuration	Show simulations with duration equal or larger (in min)	-1 (show all)	360
trigger	Simulation trigger type (all, automatic, manual)	all	manual

New filters become available after saving the configuration and restarting TOAST.

Sorting¶

The lower drop down menu is for sorting. Per default the simulations are sorted by overall residual. Other possibilities are:

Creation time
Magnitude (M)
Depth (D)
Duration (Simulation time span)
Simulation backend

Icons view¶

The Icons view allows a fast assessment of the situation.

The header displays:

Preferred (as star, only if set)
Label (if not set then Magnitude and Depth)
Simulation backend
Simulation time span
Progress (while computing)
Error symbol (if aborted, hover mouse for more details).

The first and larger icon is used to identify currently active simulations: if the dark part of the beach ball is colored, this simulation is active and used for the other perspectives as well (Map, Arrivals, Displacements, Forecast Zones) and visualized there using the same unique color. Black means the simulation is not active.

The smaller icons represent:

Event residual
Focal mechanism residual
Expected rupture mechanism residual
Tsunami arrival residual
Displacement residual, see also: Displacement residual
Wave radar residual (not implemented yet).

For more details, place the mouse over the symbols and consult the hover tooltips or see the table in Details view.

The color code under the smaller icons displays matching quality between the simulation and observed data. The color range is from red to green based on following definitions: For residual 0 -> green; 0.5 -> yellow; 1 -> red.

Black means that a comparison is not possible since either simulated or observed data is not available.

The overall residual is shown in form of the colored bar on the left side.

While a simulation is being computed, the estimated progress is shown on the upper right.

Details view¶

In Simulations mode in Details view (activate by clicking the list-icon on the upper right), the Database panel displays following information.

Columns in *Simulations mode* in *Details view*¶

Add simulations¶

See: Simulations on how to generate simulations automatically or to add simulations to an incident manually.

Displacement residual¶

If displacements were computed by simulations and if for at least one GNSS station either both the east and north components or the up component of the observed displacement are present, then the mismatch between observed and simulated displacements is computed in form of the displacement residual and shown in the database panel.

The residual is computed in following way:

$Misfit &= \sqrt{\sum_{i}^{Stations} \sum_{j=E,N,U}^{Components} a_{ij} \cdot (d_{ij}^{o}-d_{ij}^{s})^2} \\[10pt] Totlen &= \max \left( \sqrt{\sum_{i}^{Stations} \sum_{j=E,N,U}^{Components} a_{ij} \cdot (d_{ij}^{o})^2}, \;\varepsilon \right) \\[10pt] Residual &= 1 \;\; \text{ if } Misfit \geq Totlen \\[10pt] Residual &= \frac{1}{2} \cdot \sin(\frac{Misfit}{Totlen} \cdot 180 - 90) + \frac{1}{2} \;\; \text{ if } Misfit < Totlen$

where $a_{ij}^{}=1^{{}}$ if both observed and simulated values are present and $a_{ij}=0^{{}}$ otherwise.

The constant $\varepsilon$ is set 0.1 m. It relaxes the computation of the residual if the total length of the observations is smaller than 10 cm and also avoids division by zero. In practice this would rarely be the case, as the observations typically have noise of a couple of centimeters.

Basically, the misfit, being the sum of the vector difference lengths between observations and simulations summed over all components and stations, is normalized by the sum of all vector lengths and mapped to values between 0 and 1 by a sine taper function.

../_images/gnss_sigmoid.png — Sine taper function mapping Misfit to a range from 0 to 1.¶

Map Layers panel¶

The Map Layers panel is used to enable/disable the display of features and simulation results in the Map perspective and Wave Propagation panel. Options are listed and explained below.

../_images/panel_map_layers.png — Map Layers panel¶

Color profile¶

Here you can select the active color profile or open the Gradient Profile Editor, see Color profiles, gradients and colors for more information.

The color or gradient defined for the layers in the selected color profile is displayed as a color bar next to the layer name. By clicking on this bar the Color Gradient Profile Editor opens with the active profile and the clicked layer selected.

Faults¶

Show/hide faults used for automatic patch generation on map, turn on labels.

Faults are shown as colored lines with triangles indicating the direction of subduction. The color corresponds to depth and follows the same scheme as the bna-files in SeisComP (which are shown as thin lines without triangles if present in ~/.seiscomp/bna).

TOAST is delivered with an extensive set of preconfigured faults covering most subduction zones. See Fault geometry configuration on how to set up additional faults.

Forecast zones¶

Show/hide forecast zones on map. If simulations are active, the color of the forecast zones corresponds to the computed warning level.

Fill: Fill color corresponds to warning level.
IDs: Turn on zone IDs.
Inactive: Do show zones without simulation results in black outline.
- Colorize: Do colorize inactive zones with lowest warning level color instead of no color.
Points: Show POI belonging to forecast zone.
- IDs: Show POI IDs.
- Names: Show POI names.

Forecast zones can be selected in Map view by clicking. Only then corresponding points are shown. If switching to Forecast Zones perspective, the same zone is selected.

Displacements¶

Show/hide coseismic displacement vectors.

Observed displacements can either be obtained automatically by messaging, be set manually or be imported from a file in XML format. See also: Displacements perspective and Import displacement amplitudes and create observed displacements. By default, they are rendered as black arrows. See Color profiles, gradients and colors on how to change the color.

Simulated displacements are computed by simulations. They are rendered in the color according to the active simulations.

The horizontal displacement is shown with a solid line, the vertical displacement with a dashed line and a semicircular arrow head. Depending on the displacement display settings, the length of the displacement is represented by the length of the arrows. A tooltip for the arrows shows additional information.

The display settings can be changed via TOAST configuration or dialog: Menu ‣ Settings ‣ Displacement vector settings or by right mouse click on Map view ‣ Layers ‣ Displacements ‣ Settings…. The Min displacement threshold allows to hide arrows with a length smaller than this threshold. Additionally, the size of the arrowhead and the line width of the arrow can be set. Using the Screen option, the length of the largest visible arrow is set to Max visible length and the length of all other arrows in relation to it. When using the Zoom option, the arrow length is scaled with the Scaling factor and changes according to the zoom level of the map. The Independent vertical scaling option enables separate scaling for the vertical displacement arrows.

../_images/gnss_settings.png — Displacement Vector Settings dialog¶

Note

The settings of the dialog are stored in the TOAST configuration in @CONFIGDIR@/toast.cfg (and not in @SYSTEMCONFIGDIR@/toast.cfg).

Legends¶

Show/hide legends. Note that only legends corresponding to features which are selected in the Map Layers panel are shown. Following image shows all possible legends.

POIs¶

Show/hide tide gauge positions on map, turn on their station codes.

../_images/poi.png — *Map* perspective with activated POIs feature¶

If simulations are active, the coloring of the tide gauge corresponds to the highest maximum wave height of the active simulations at that location.

If Cluster is selected, nearby stations are grouped and shown as a circled number, the color is according to the highest value in the group. Grouping is dynamically adjusted depending on zoom level.

Rupture area¶

Show/hide the Rupture area of the active simulations.

../_images/rupture_patch.png — *Map* perspective with activated Rupture area feature¶

This option enables the display of the patches which were used for the simulations. The colored bar indicates the deeper side of the patch, the color corresponds to the simulation color.

Simulation layer¶

Show/Hide simulation layers.

Simulation layers show additional information for the available simulations (e.g. the location of precomputed TsunAWI simulations). If no simulation layer is available, this option is hidden.

Wave propagation¶

Show/hide wave propagation layer for active simulations in the Map perspective and Wave Propagation panel.

Use the Simulation player to select a time for isochrones and ssh. See also: Display simulation results.

Wave Propagation panel¶

This panel shows numerical values for the active simulations for those features which are selected in the Map Layers panel. Move the mouse in the Map perspective to get values at different locations. If several simulations are active, then the worst-case value is shown (maximum for wave heights, minimum for arrival times).

Color profiles, gradients and colors¶

Each profile consists of different types that define the colors or gradients of map-related features like Forecast zones warning levels or SSH max. The current active profile is shown in the Map Layers Panel, for more informations see Color Profile in Map Layers Panel.

Create and modify color profiles¶

By default, all simulation related results are color coded according to the DefaultProfile. This profile can not be changed, but new profiles can be added using the Color Gradient Profile Editor. To launch it, select Configure… in the the Color profile drop-down menu of the Map Layers Panel. Alternatively you can click on one of the color bars there or use Menu ‣ Settings ‣ Color profiles….

../_images/color_profile_editor.png — Color Gradient Profile Editor¶

First, add a color profile by clicking on New or Copy. New creates a new color profile based on the default profile, while Copy copies the selected profile. Then select the tab of the feature you want to edit. Next select the color or gradient you want to use for the feature in the drop-down menu. If the existing colors or gradients do not match your desired settings, you can change them using the Color Gradients Editor. To launch it, you can click on the colored bar representing the color or gradient.

The minimum and maximum values below the color bar are by default set to the minimum and maximum values defined in the selected color gradient. You can override them by selecting Overall gradient mapping, in which case the whole gradient is linearly mapped to the range of these values. This is useful if a quick change is necessary.

Click Save, to save the color profiles. Now you have a new color gradient profile which can be selected in the Map Layers panel.

The color profiles are stored in the file /home/sysop/seiscomp/share/toast/mapstyles, see also Color profiles, gradients and colors configuration.

Note

Overall gradient mapping is deactivated for default profile features or when a color is selected.

Create and modify colors and gradients¶

The Color Gradients Editor is a tool for creating, changing and removing colors and gradients. To launch it, click the color bar in the Color Gradient Profile Editor or select Menu ‣ Settings ‣ Gradients and colors….

../_images/color_gradient_editor.png — Color Gradients Editor¶

Add a new gradient or color by clicking on New or Copy or by right mouse click on one of the present gradients and using the context menu actions. New creates a empty color or gradient based on your last selection, while Copy creates a copy of the current selected item. Select a gradient or a color from the list to edit it.

Note

Gradients and colors assigned in the default profile or assigned to multiple profiles are immutable. You can see the corresponding profiles by hovering over the gradient or color item in the list.

In Gradient mode you can edit gradients. The gradient thresholds are shown as black arrows below the color bar. Select a threshold to edit the corresponding value, color and label. Add new thresholds with double click or right mouse click on the color bar. By right mouse click on an arrow, you can remove it. Select Interpolated for a continuous gradient or change the Unit. The value of the currently selected threshold can be changed with the Value edit or by sliding the threshold arrow underneath the color bar. The color of the currently selected threshold can be set by clicking the colored square icon. Note that transparency is defined using the Alpha value: 0 means transparent and 255 means opaque. The # opens a dialog for changing the label. The … icon opens the Color Table Editor for editing values (Key column), colors (Color) and labels (Tag).

Select Single color to edit a gradient containing only one color. In this mode you can select the color by clicking on the color bar. Add or change the tag and the unit of the color. Currently only Displacements - Observed and Iso chrones use Single color mode.

../_images/color_table_editor.png — Color Table Editor¶

Click Save, to save the colors and gradients. Now, they are available in the color profile editor.

The gradients and colors, like the profiles, are also stored in the file /home/sysop/seiscomp/share/toast/mapstyles, see also Color profiles, gradients and colors configuration.

Task Manager¶

The task manager lists all processes started by TOAST. Processes can be killed using right mouse click. The task manager is opened using Menu ‣ Extras ‣ Task manager or by clicking the gear icon on the right of the status bar. The first number in the icon shows the number of running, the second of pending processes.

System Log¶

In order to display the system logging output, click the Show system log button in the status bar on the lower right of the TOAST window or via Menu ‣ Extras ‣ System log. Use the buttons on top for filtering.

Use the settings icon to select which channels should be received and notified (latter in form of an icon in the status bar). Note that the selectable option on the bottom: Send only notifications if the warn level increases is related to system channel type and has nothing to do with tsunami warning levels.

Incident Log¶

The incident log contains information starting from incident creation to execution of simulations, manual setting of threat levels and picks or dissemination of bulletins. The log viewer can be opened via Menu ‣ Extras ‣ Incident log, with the shortcut CTRL+I or by clicking the Show incident log button in the database panel in Simulations mode. It always shows the logs for the currently selected incident.

The logs for each incident are stored in a text file: @CONFIGDIR@/log/toast-incidents/YYYY/MM/eventID.log, where the date refers to creation time (not origin time). The log files can be opened directly using the context menu on an incident in the database panel in Incidents mode. Note that these files are never deleted by TOAST, even if an incident is removed.
