An accumulation of moving images and sounds, Medium Earth is an audio-visual essay on the millennial time of geology and the infrastructural unconscious of Southern California. Focused on the ways in which tectonic forces express themselves in boulder outcrops and the hairline fractures of cast concrete, Medium Earth participates in the cultures of prophecy and forecasting that mediate the experience of seismic upheaval. The desire to evoke the hidden substrata of the planet gives way to a morphological interpretation of the face of the earth. As an experiment in channelling the system of fault lines buried below California, Medium Earth animates the stresses and strains of physical geographies undergoing continental pressures.
