GAPS / WebApps

Web based earthquake analysis

Overview

What is GAPS?

GAPS is our application server integrated into the SeisComP framework. It exposes interfaces accessible through the HTTP or the WebSocket protocol closing the gap between desktop and web-based access to SeisComP. It provides:

GAPS is optimized for high load, serves static files like css, html, js and exposes an Ajax API to receive SeisComP objects likes picks, quality parameters as well as data records in real time. GAPS complements QuakeLink to build interactive and responsive Web applications for SeisComP.

GAPS ships with highly interactive modern web applications to monitor seismic activities and to show real time data of your network or monitor station qualities. Event information is accessed in real-time and from archive via QuakeLink. QuakeLink is therefore provided along with GAPS.

Demo Documentation

EQView

Monitor seismic activity

EQView shows the recent seismic activity, most likely earthquakes, in predefined regions: widgets. Each widget shows one region with custom event filters, e.g. all events not older than one week with magnitude above 5. The region widgets are shown in the upper right corner.

When a new event has been detected, a panel will open (see screenshot: lower left corner) showing the traces of the next 10 stations along with more detailed information. After a configured time span that panel will close itself again. Furthermore the most recent event is blinking in the main panel as well as in the widgets.

StationView

Monitor station quality

StationView shows a map with all configured stations of your SeisComP installation. The color encodes the currently activated parameter:

  • Delay
  • Latency
  • Ground motion

The red border of the station symbol indicates that a pick (a detection) has been made. The more opaque the border the more recent it is. Clicking on a station opens the panel (see screenshot: left side) showing the last 10 minutes of real time data along with more detailed information.

TraceView

Data and event analysis

TraceView visualizes your real time data streams just like scrttv. In addition it shows the latest event indicated by a green line with magnitude and region and all P and S phase detections.

OriginLocatorView

Data and event analysis

The OriginLocatorView supports your event and data analysis on the web browser on a PC or a mobile device. It is an optional component of GAPS.

  • Select events from table or map
  • Activate or deactivate phase picks
  • Phase picking:
    • view 3-component data
    • filter waveforms
    • add or adjust phase picks
  • Relocation by configurable locators
  • Discriminate events
    • set the event type
    • set origin status
