RFSB borehole

Location:

RFSB is located at the Richmond Field Station of UC Berkeley, a few miles north of the campus.

This station serves both as a borehole site in the Hayward fault network and as a surface installation of an accelerometer in the Berkeley Digital Seismic Network.

Geology:

Shale

Vault/Borehole conditions:

The HFN seismometer package is deployed at a depth of 91 meters in the borehole. The accelerometer is installed in a barrel at the surface.
