ScienceĪ primary objective of the PBO was quantify three-dimensional deformation and its temporal variability across the active boundary zone between the Pacific and North American plates.Ĭentimeter to millimeter-level measurements of surface and near surface motion through Global Positioning System (GPS) stations, borehole geophysics, long-baseline laser strainmeters, accelerometers, and geodetic imaging has far reaching implications regarding earthquakes, volcanic unrest, subsidence, landslides, extraction or injection of fluids, loading or unloading of water, ice or snow, and other Earth processes. Michael Jackson, and the current Director of UNAVCO Geodetic Infrastructure, Dr. Principal Investigators (PI) for the Plate Boundary Observatory have included, former UNAVCO Presidents, Dr. UNAVCO was responsible for design, instrument installation, ongoing maintenance, communications, data archiving, data processing, and data availability for the geodetic instruments that comprised the Plate Boundary Observatory. The Network of the Americas (NOTA) is a federated network comprised of stations that were part of the the former EarthScope PBO, COCONet, TLALOCNet networks. The Plate Boundary Observatory (PBO) component of the NSF EarthScope program precisely measured Earth deformation resulting from the constant motion of the Pacific and North American tectonic plates in the western United States.
