"Parkfield Interventional EQ Fieldwork" (PIEQF) - Seismic Art

Parkfield Interventional EQ Fieldwork (PIEQF) is a geologically interactive, kinetic earthwork that has been installed in the township of Parkfield, Central California. This machine controlled earthwork is triggered by near real-time reported Californian earthquakes from Magnitude M 0.1 and above.
This machine earthwork is feedback loop between the seismicity of California and a physical and mechanical representation of all Californian seismic events. Each time a Californian earthquake occurs, an array of 5/8 inch steel rods attached to an earthquake shake table oscillate and resonate, reflecting the dynamic nature of the Californian landscape. On average 30-60 seismic events occur throughout California daily.
