This event is the first likely marsquake recorded by the InSight team. Several other seismic events have been recorded but are much more ambiguous than this signal.
The audio underscores just how seismically noisy the Martian surface can be and was produced from two sets of sensors included with SEIS. You can hear sounds from the Very Broad Band sensors from your left speakers and sounds from the Short Period sensors from your right speakers. Audio from both sets of sensors have been sped up by a factor of 60; the actual vibrations on Mars would not have been audible to the human ear. Playback on headphones or speaker system recommended for best experience.
