Quake Sol 173 by NASA

A recording of a magnitude 3.7 marsquake from InSight's seismometer, called SEIS. This quake was recorded on May 22, 2019 (the 173rd Martian day, or sol, of the mission). Far below the human range of hearing, this sonification from SEIS had to be sped up and slightly processed to be audible through headphones.
