Plate Boundary Observatory at PARI

The Plate Boundary Observatory is best described in their own words:

"The Plate Boundary Observatory (PBO), part of the EarthScope project that is funded by the National Science Foundation, studies the three-dimensional strain field resulting from active plate boundary deformation across the Western United States.

From a science perspective the PBO component of EarthScope is a geodetic observatory designed to study the three-dimensional strain field resulting from deformation across the active boundary zone between the Pacific and North American plates in the western United States. The observatory consists of arrays of Global Positioning System (GPS) receivers and Strainmeters which will be used to deduce the strain field on timescales of days to decades and geologic and paleoseismic investigations to examine the strain field over longer time scales. "

Realtime cleaned data from the PBO instrument at PARI, made available through EarthScope (; EAR-0323309), supported by the National Science Foundation.
