Project Overview Between December 2014 and February 2015, UNAVCO installed 10 accelerometers at existing Plate Boundary Observatory (PBO) GPS sites in the San Francisco Bay Area. Accelerometers in combination with high-precision GPS data provide a new interdisciplinary data type: full spectrum displacements based on an optimal combination of geodetic and seismic data. These can significantly … Continued

Project 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 … Continued

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

Project Overview Mauna Kea, a dormant 13,800-foot-tall volcano on the Big Island of Hawaii, is experiencing substantial natural and human-caused erosion at its summit. The goal of this project is to monitor these erosion rates by providing a baseline high-resolution topographic map of the summit area to quantify natural and anthropomorphic influences. The project will … Continued

Project Overview Dartmouth-University of Maine-University of New Hampshire project is to reconstruct the history of precipitation and atmospheric circulation in Alaska during the last thousand years using ice core records of snow accumulation. The project centers around two new ice cores collected to bedrock (208 m) from the Mount Hunter Plateau in the Alaska Range of Denali … Continued
