For the installation Earth 2010, Finnbogi Pétursson creates an interference wave measuring 7.8Hz in a pool of water. The tone, which can be heard and physically detected, is visible on the surface of the water in the form of waves. The frequency of 7.8 hertz corresponds to the physical phenomenon known as the Schumann Resonance, which is the frequency of the Earth’s electromagnetic field. For Pétursson, this frequency represents the primal pulse of our planet. The first video is Pétursson’s own professional video. The second is my fuzzy hand-held that zooms in on the reflected wave patterns.
