Palmer Station, Antarctica (seismic)

This near-real-time audio stream originates from a seismometer at Palmer Station, Antarctica (IRIS/USGS station PMSA). The low-frequency sounds of the solid Earth have been speeded up by a factor of 500× to make them audible. As a result, frequencies have been transposed upward about 9 octaves. Each successive audio program (separated by a brief pause) compresses the last 48 hours into about 6 minutes (exactly 05:45) of listening time.
