Technical Specifications

The Raspberry Shake was designed and built by OSOP, S.A.

Storage is now user configurable and can be much longer than 7 days, which is the default. Raspberry Shake is also Wifi compatible.

Instrument response Files

The Raspberry Shake 1D, 3D and 4D velocity channels have flat frequency responses from ~0.5 Hertz (2 seconds) to 80% Nyquist, or ~20 Hz for the 1D and ~40 Hz in the case of the 3D and 4D.

See below to download a nominal instrument response file for your Raspberry Shake in SeisComP XML, RESP and/ or dataless SEED formats. If you have data forwarding turned on, then an instrument response file for your specific shake can be downloaded in XML format by clicking on your Raspberry Shake’s station icon at StationView.

The instrument response files are provided below in 3 formats:

  • Modern seiscomp-xml format for use with SeisComP3 and SeisComPro
  • RESP for use with Earthworm (AQMS, Earlybird, Hydra), PQLX, SQLX, SEISAN
  • dataless SEED

Timing Quality

In the Raspberry Shake, data packet time stamps are done using Network Timing Protocol (NTP) time. Timing quality is +/- 20 ms for the 1D. To give you an idea what this means, consider an earthquake’s P-wave traveling at a very fast 6000 m/s. With an uncertainty of +/- 20 ms, this translates into a location uncertainty of only +/- 120 meters. For lower P-wave velocities, the uncertainties diminish. This uncertainty is well within a reasonable margin of error for locating earthquakes.

RPi’s supported

The Raspberry Shake 1D has been thoroughly tested with 3 Model B and less so with the other models in this list:

000[d,e]: Model B, 000f and other modules that lack mounting holes are not supported

00[10,13]: Model B+

a[01040,01041,21041]: 2 Model B

9000[92,93],920093: Zero

a[02082,22082,a32082]: 3 Model B

9000c1: Zero W

Related products:

  • Raspberry Shake 3D and 4D and Raspberry Jam supported modules:

    00[10,13]: Model B+

    a[01040,01041,21041]: 2 Model B

    a[02082,22082,32082]: 3 Model B

    The software would run on all of the RPis listed for the 1D, but the form factor is for the 2/3 Model B only.
