Plate Boundary Observatory The Plate Boundary Observatory (PBO) is a network of more than 1,200 continuous GPS instruments, borehole strainmeters and seismometers, and tiltmeters installed primarily throughout the Western United States. The objective of PBO is to explore land motions related to movement of the Pacific, Juan de Fuca, and North American tectonic plates; such motions inform … Continued
Overview Determining how the Caribbean plate moves with respect to the neighboring North America and South America plates has been a major challenge. Geologic plate motion models using seafloor magnetic anomaly rates, transform fault azimuths, and slip vectors are challenging due to sparse data. The only rates come from the Cayman Spreading Center, and seismicity … Continued

Overview POLENET in Antarctica is a multidisciplinary NSF-funded project examining the geology and geophysics of the Antarctic continent. The associated network of autonomous GPS and seismic equipment spans much of the continent, enabling researchers to explore the geological history of the Trans-Antarctic Mountains, the structure of the Antarctic lithosphere, and the dynamics of continental ice … Continued

Overview UNAVCO is supporting the design and construction of more than 40 new permanent GPS stations in the greater Houston metropolitan area. This network, called HoustonNET, will provide data for a study undertaken by Dr. Bob Wang from the University of Houston to measure ground subsidence in the region. In January of 2014, UNAVCO engineer … Continued
