Location:
Site is located south of Antioch, California, in a former lignite and sand mine in the Black Diamond Mines Regional Park, under the auspices of the East Bay Regional Park District.

Geology:
Sand

Vault/Borehole conditions:
The instruments are sited approximately 150 meters into an old mine tunnel. There is a ~100 meter overburden composed of sandstone, shale, and coal, which limits thermal fluctuations. In addition, 7 centimeters of foam cover the instruments.

Data Availability:
BDSN waveforms and associated metadata are available at the Northern California Earthquake Data Center (NCEDC).

Several tools provide access to SEED format data at the NCEDC, both in terms of querying the archives and allowing data requests.

Help on using these tools is available.
