The Plate Boundary Observatory (PBO), one of the core components of EarthScope, is a geodetic observatory designed to study
the three-dimensional strain field resulting from plate boundary deformation in the western US including Alaska. The science
goals of PBO require that plate boundary deformation be adequately characterized over the wide range of temporal and spatial
scales common to active continental tectonic processes. To meet these goals, PBO will install a core of geodetic
instruments that possess excellent sensitivity over this broad temporal spectrum, with a deployment configuration that will
dramatically increases the spatial scale and density of stations. The PBO Facility will consist of 891
permanently-installed GPS stations, 175 borehole strainmeters, five laser strainmeters, and a pool of 100 portable GPS
receivers for temporary deployment and rapid response for volcanic and seismic crises. PBO will provide a range of data and
data products for scientific investigations and for education and outreach activities. Congress has provided funding for
EarthScope to the National Science Foundation and a proposal to construct EarthScope has received approval from the National
Science Board. Construction is expected to commence in September or October 2003.
