The Mid-Plate Primary Node, located between Axial Seamount and the Pacific City Shore Station, is important because it provides one of the few mid-plate sites that will enable future study of stress propagation through the plate as well as intraplate deformation and its relation to plate boundary failure. The site will not be equipped with core sensors when first installed. It provides the capability for future support of requirements as described in OOI Science Requirement document A5-Plate Scale Seismological and Geodynamics. The Mid-Plate Primary Node will be installed with a nearby cable extension of approximately 5 km (or sufficient length to enable pick-up by a ship) to allow for the option of expansion to establish additional node and/or science sites (should opportunity and funds become available after construction).
