Berkeley Borehole Network

The Berkeley Borehole Network is composed of stations from two experiments: the mini-Plate Boundary observatory and the Northern Hayward Fault Network

mini-PBO

A collaborative effort of the Berkeley Seismological Laboratory, the U.S. Geological Survey (USGS) at Menlo Park, the Department of Terrestrial Magnetism at Carnegie Institution of Washington (CIW), and the IGPP at UC San Diego (UCSD), mini-PBO augments existing infrastructure in central California to form an integrated pilot system of instrumentation for the study of plate boundary deformation, with special emphasis on its relation to earthquakes.

The borehole component is focused on the San Francisco Bay area, and augments existing instrumentation along the Hayward and San Andreas faults with up to 8 sites with borehole tensor strainmeters and seismometers, downhole pore pressure and tilt sensors, and geodetic GPS receivers.

For current mini-PBO information as well as individual station pages, please see the Berkeley Seismological Lab's BBN pages.

NHFN

Operated by the Berkeley Seismological laboratory, the NHFN is an array of borehole instrumentation deployed in the San Francisco Bay Area, with the goal of monitoring microseismicity on the Hayward fault.

For current NHFN information as well as individual station pages, please see the Berkeley Seismological Lab's BBN pages.
