GPS Tracks Ground Deformation

USGS Field Engineer Ben Pauk records site and equipment information for the Global Positioning System (GPS) installed at the North Rim station in the Newberry National Volcanic Monument. The GPS records the precise position of the station, including latitude, longitude and elevation. Tracking subtle ground deformation through GPS provides insight into how volcanoes can change over time in response to changes in the magmatic system deep beneath the volcano, or in response to regional tectonic stresses.
