In this video you see the visualised seismic signal of registrations from three seismic stations in Japan (Matsushiro, MAJO, Erimo, ERM) and Russia (Yuzhno Sakhalinsk, YSS) before, during and after the Tohoku Earthquake in Japan. The flashes on the map correlate the signal magnitude at the three stations.
At the same time you can listen to the sonified seismic signal, made audible by an acceleration of factor 1440. This so called audification of the earth's activity turns the ground motion of two days into an audio track of 120 sec.

The facilities of the IRIS Data Management System, and specifically the IRIS Data Management Center, were used for access to waveform and metadata required in this study. For the data sonification we used Sonifyer, a software tool developed at Bern University of the Arts (CH).

  • That first Ka-Boom really shook me - not that it was loud, but at how well it illustrated how this earthquake hit hard and suddenly. I would have expected some sort of gradual build up first.

    Very interesting. Thanks for posting.

    The audio signal is compressed, in the uncompressed version is the intensity of the earthquake frightening.

  • Yeah... that about sums up those days for me too.. Constant rattling... the big quake itself which was especially felt up here in Hachinohe as well.. every time the ground rattled we alls topped in worry...

  • Indeed. Where could one find the uncompressed version?

  • could you share the uncompressed sound file? Thanks.

  • Where could one find the uncompressed version? This is outstanding...

  • it sounds like a car crash, or the crunches from a trash compactor
