Plate boundary observatory overview

In this overview of the Plate Boundary Observatory (PBO), Glen Mattioli, director of geodetic infrastructure at UNAVCO, provides an overview of its important activities and impact. EarthScope scientists developed this network of instruments to carefully measure changes in the Earth's surface caused by the interaction between the Pacific and North American tectonic plates along the border of the western United States and Alaska. The PBO system employs a variety of approaches and equipment to make these detailed measurements, including Global Positioning System (GPS) stations, laser strainmeters, and geodetic imaging. PBO data offer valuable new insights into many Earth processes such as earthquakes, volcanism, and tsunamis. It is even being used to help manage water resources by offering new ways to measure groundwater, soil moisture, and snow.
