Right here, right now, the solid Earth is moving beneath your feet.

The rumblings of earthquakes half a world away, the waves from ocean storms far out to sea, the twice-daily pull of Moon and Sun: these natural forces all combine to weave a shifting tapestry of slow vibration within the solid Earth. Too low for us to hear, too slow for us to feel, these subsonic movements reverberate throughout the planet at this very moment, just as they have done for millennia past and will continue for countless more.

Earth Sound CD

What would we hear if our senses had evolved to respond to these deep waves of planetary energy? If we could only slow the scale of human time a few hundred- or thousand-fold, if our tiny ears could only swell to match the measured pace at which these long vibrations move: perhaps then we might begin to really hear our planetary home.

This is what I do. I transpose seismographic recordings of the Earth’s vibrations into the range of human ears, to lift the deepest sounds of Earth into the field of human perception.

Recently I have begun developing methods of listening to these low seismic Earth sounds in near real-time, thereby giving the listener a much more immediate and direct experience of the sounds of Earth. Details to come later in 2011...

Meanwhile, here are some samples of the kinds of sounds I’ve found along the way.
