Hollister, CA, USA (seismic)
This near-real-time audio stream originates from a seismometer at Hollister, CA, USA (BK station SAO). The low-frequency sounds of the solid Earth have been speeded up by a factor of 1,800× to make them audible. As a result, frequencies have been transposed upward about 11 octaves. Each successive audio program (separated by a brief pause) compresses the last 168 hours into about 6 minutes (exactly 05:36) of listening time.
