The Plate Boundary Observatory (PBO) Network consists of several major observatory components: a network of 1100 permanent, continuously operating Global Positioning System (GPS) stations many of which provide data at high-rate and in real-time, 78 borehole seismometers, 74 borehole strainmeters, 26 shallow borehole tiltmeters, and six long baseline laser strainmeters. This page links to the State of Health pages for the network.

• PBO GPS Network consists of 1100 permanent continually-operating GPS stations spans the rapidly-deforming Pacific/North-American plate boundary in the western United States and Alaska, with additional stations on the stable continental interior. The normal GPS observation data sampling interval is 15 seconds.
• PBO Real-Time GPS Network consists of a subset of the 1100 permanent continually-operating GPS stations which stream BINEX with GPS observation data at a sampling interval of 1 second.
• PBO Strainmeter Network consists of 78 permanent borehole strainmeters spans the rapidly-deforming Pacific/North-American plate boundary in the western United States and Alaska, with additional stations on the stable continental interior.
