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.

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. Info 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.

The network status tab (fig. Network status tab) visualizes the timing quality of the whole seismic network. The colors of the triangles represent the data latencies/delay of the station. More detailed information about station quality can be derived by opening an information widget (fig. Info 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.

In addition to the current event scmv can show all events it has currently saved in its session. This depends on the configured time span it remembers events. This can give a nice overview of the network activity. The circles are again colored by depth and sized by magnitude.

Show historic origins

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

The information widget opens by right mouse click on a station or event 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.

Info 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).
