scmv

Map view

Description

scmv visualizes the actual information regarding earthquakes, trigger status, ground motion and station quality. This information is visualized in a map showing also the topography of the region including bathymetry, state borders and geologic faults. scmv provides two different tabs with maps showing the ground motion and the network status.

Ground motion status

The ground motion tab (fig. Ground motion tab) shows the actual groundmotion in nm/s at each station color-coded. Furthermore the trigger status (new picks) of the stations are announced by blinking triangles (the same in all other tabs). In case a new pick is associated to an event, the blinking color changes from red to green (default). Events are represented by open circles and the depth is color-coded. By right mouse click on the symbol of a station more detailed information are shown in an information widget (fig. Station information widget).

Ground motion tab

Tab 1-2 = Ground Motion, Network Status tab; Station A = station with ground motion between 0 and 200 nm/s; Station B = triggering (red blinking) station; Station C = station of undefined status; Station D = triggering and associated station (green blinking); EQ = location of the earthquake/event; P = spreading of the P-wave; S = spreading of the S-wave; Legend = ground motion scale.

Network status

The network status tab (fig. Network status tab) visualizes the quality control parameters of all shown stations. The colors of the triangles represent the data the selected parameters of a station, e.g. latency or delay. More detailed information about station quality can be derived by opening an information widget (fig. Station information widget left) with a right mouse click on the symbol.

Network status tab

Station A = station with up to 20 sec data latency/delay; Station B = station with up to 10 min data latency/delay and a warning; Station C = disabled station; EQ = location of a recent or historic earthquake/event; Legend = scale of the delay; Status = connection status.

The visualized QC parameters can be selected in the QC parameters widget of scmv.

QC parameters selection widget

The station information widget opens by right mouse click on a station symbol in one of the scmv maps. The widget gives a more detailed list of parameters. For a station general information (coordinates, network code etc.), quality parameter (latency, gaps etc.), amplitude information and the actual waveform data are provided. For an event information like the location, the number of stations and the azimuthal gap are shown.

Station information widget

The info widget of a station shows station information like network code and location. The quality of the station can be checked here. The lower part shows the last 15 minutes of waveforms including picks (if available).

Event information

In addition to the current event scmv also shows all events it has currently saved in its session as circles. This depends on the configured time span it remembers events. Showing the events can give a convenient overview of the network activity. If available focal mechanisms are displayed with dashed lines connecting to their location. The circles and focal mechanisms are again colored by their depth and sized by magnitude.

Show historic origins

All historic origins currently saved in scmv are shown as circles.

The events shown an the map can be confined by selecting the mode and the status of preferred origins in the event selection widget.

Event selection widget

The event information widget opens by right mouse click on an event symbol. It shows event details. Clicking on the “Show Details” button allows to open the preferred origin of the event in other GUIs such as in scolv.

scmv inherits global options.

displaymode

Type: string

Set one of the available displaymodes: groundmotion or qualitycontrol

groundMotionRecordLifeSpan

Type: int

Unit: s

Sets the maximum latency in seconds of the ground motion records to be valid. Default is 300.

removeEventDataOlderThan

Type: double

Unit: s

Sets the time span in seconds to keep events. Default is 43200.

readEventsNotOlderThan

Type: double

Unit: s

Sets the time span in seconds to read events initially from database. Default is 0.

centerOrigins

Type: boolean

If a new origin/event is set/selected this option defines if the map is centered or not at the origin location. Default is false.

eventActivityLifeSpan

Type: double

Unit: s

Time span of which an event is active after origin time to show blinking associated stations. Default is 900.

expiredEventsInterval

Type: double

Unit: s

A positive value (greater than zero) defines the interval to check for expired events. A negative or zero value disables the interval check and expired events are only removed when a new event is declared or an existing event is updated. Default is 0.
