Streams – Realtime Display

Display and archive live earthquake data on your own personal computer! Subscribe to data feeds from hundreds of global seismic stations and any other SeedLink servers (including many popular seismographs), or feed Streams with common format data files via FTP.

Streams can do so much more when used with Gecko seismographs, with integrated recorder control and configuration, and broadcast streaming for event association and notifications. Download free for Windows, macOS, Ubuntu 20.04.

Streams 3.4 improved speed and fixed a bug related to duplicate data archives. It also includes a link to an acknowledgment page listing public data libraries and sources that we have used in our free software.

Streams 3.3 brought a number of enhancements, including better handling of blocked connections on Windows for Gecko seismographs. It also includes new features:

  • Optionally save SeedLink streams to disk
  • Added a list of public SeedLink servers to choose from, including their corresponding FDSNWS StationXML lookup address
  • Event alert sounds are back!
  • The latest version of Waves is built-in
  • Gecko settings and controls are now tabbed for ease of use
  • Support for new Gecko histogram logging interval setting

Streams 3.2 integrated Waves 4 with interactive earthquake location & magnitude calculation, and optionally stores Gecko data in a similar folder hierarchy to that on the Gecko’s SD card. Alert message were also displayed in local time, and the macOS installer now works with Apple security protocols.

Streams 3.1 added remotely accessible web page views of your station and Gecko station status, and introduced some Gecko remote control actions.

Streams 3.0 took over from the Live Stream name by introducing input from SeedLink data sources, and the macOS and Ubuntu versions can also share incoming Gecko data via SeedLink.

If you’re monitoring a building or dam. you can see live data in your control room with Streams, which can colour code the displayed seismic data channel as a [WARNING] or [ALERT] based on your desired signal level thresholds. You can set alarm levels in velocity (mm/s) and acceleration (mm/s² or g) which can be sent out via email. The amplitude of the display can be set to a fixed level of acceleration or velocity to show how close the signal is getting to the colour bands of your customised alarm levels.

Time scale buttons in the toolbar allow you display the last 1, 2, 5, 15 or 60 minutes on screen, and if the displayed data is particularly interesting you can simply tap the Waves button to pop up a data analysis window. Each channel shows the peak amplitude for the on-screen data, and the estimated MMI or PEIS earthquake intensity for acceleration data. Other controls in the coloured channel box allow you to modify that Gecko’s settings, hide or filter a channel, or request older data from the SD card of a Gecko seismograph.

Streams has Event detection that immediately requests data from all connected Gecko recorders when any remote station detects an earthquake, meaning you get data from all stations quickly and automatically, even if they are not normally streaming data continuously.
