Borehole Pore Pressure Sensors

A pore pressure senor is an in-situ device designed to measure fluctuations in groundwater pressure. The purpose of the pore pressure sensors is to help characterize the hydrological response of the site at time scales of seconds to years.

For example, twenty-three pore pressure sensors were installed in the Anza, Parkfield and Pacific northwest PBO strain meter arrays as part of the Plate Boundary Observatory (PBO). All are co-located with PBO strainmeters and seismometers.
