Kwajalein Atoll, Marshall Islands (seismic)

This near-real-time audio stream originates from a seismometer at Kwajalein Atoll, Marshall Islands (IRIS/IDA station KWJN). The low-frequency sounds of the solid Earth have been speeded up by a factor of 1,000× to make them audible. As a result, frequencies have been transposed upward by about 10 octaves. Each successive audio program (separated by a brief pause) compresses the last 96 hours into about 6 minutes (exactly 05:45) of listening time.
