About PBO Data

The Plate Boundary Observatory collects, archives and distributes data from a broad network of over 1400 geodetic and seismic instruments located across the continental United States and Alaska.  These data are freely and openly available to the public, with equal access provided for all users.  PBO's data products include the raw data collected from each instrument (called Level 0 data), quality-checked data in formats commonly used by PBO's various user communities (Level 1 data), and processed data products such as calibrated time series, velocity fields, and error estimates (Level 2 data). 

PBO maintains data archives at the UNAVCO Data Center, UC Berkeley's Northern California Earthquake Data Center (NCEDC) and the IRIS Data Management Center (DMC).  Data for each type of instrument can be accessed from the individual data web pages in this section of the PBO website or directly from the archives themselves.  Information on the available methods of data access is provided on the data web pages themselves.

PBO Data Statistics

The Plate Boundary Observatory has archived over 15 TB of data since the beginning of the PBO project, not including the 26 TB of Airborne Lidar and InSAR data collected under the GeoEarthScope program.  PBO has delivered over 22 TB of data to the public during the same period.  GPS data forms the majority of PBO data archived and delivered due to the large number GPS stations in the PBO network, but data types are also heavily used relative to the volume of data collected.

Acknowledging use of PBO Data
