AB: The Plate Boundary Observatory (PBO), part of the larger NSF-funded EarthScope project, will study the three-dimensional strain field resulting from active plate boundary deformation across the Western United States. PBO is a large construction project involving the reconnaissance, permitting, installation, documentation, and maintenance of 875 permanent GPS stations in five years. PBO has a demanding 5-year project installation schedule, for both GPS and strainmeter installations. During the second year of the project, the GPS Operations of PBO had accelerated production goals in reconnaissance, permitting, and installation activities. Some of the construction highlights in Year 2 include the Mount Saint Helens emergency response, the Magnitude 6.0 Parkfield earthquake emergency response, and GPS installations on the Akutan Volcano. GPS operations also prioritized permitting activity and installations in response to the Magnitude 5.2 Southern California earthquake and the Magnitude 6.7 Northern California earthquake in June, 2005. In addition to network construction, the GPS operations stepped up its maintenance activities which will continue to accelerate over the course of the project. To date, PBO has installed 270+ of the 482 GPS stations scheduled to be installed by the end of Year 3.
