PBO Borehole Data Access


PBO Borehole Data Access

As part of the EarthScope Plate Boundary Observatory (PBO), UNAVCO has installed and maintains instruments and associated data from 79 boreholes of depths from 78 to 224 meters (256-735 ft). Instruments include strainmeters, seismometers, pore pressure sensors, environmental sensors, and tiltmeters. Access to the various data sets is free and is described below. Data are available through UNAVCO, the Northern California Earthquake Data Center (NCEDC), and the IRIS Data Management Center (DMC). Data are available in SEED, bottle, XML, Ice-9, and/or ASCII formats.

Strain Data

The PBO network contains 74 borehole strainmeters. Data are available in SEED, bottle, and ASCII formats.

Seismic Data

The PBO network contains 78 three-component, high-frequency short period seismometers, 73 of which are co-located with borehole strainmeters. Data are available in SEED format from the NCEDC and IRIS DMC.

Tilt Data

The PBO network contains 26 tiltmeters, co-located with either GPS stations or borehole strainmeters. In the latter case, the tiltmeters are installed in the borehole with the strainmeters. Data are available in ASCII format from UNAVCO.

Pore Pressure Data

The PBO network contains 19 pore pressure sensors, co-located with borehole strainmeters. Data are available in ASCII format from UNAVCO.

Environmental Data

Temperature, atmospheric pressure, and rainfall data are available at a number of BPO borehole and tiltmeter sites. Data are available in bottle and in ASCII formats from UNAVCO and in SEED format from the NCEDC and IRIS DMC.
