Location:
The site is located at the Hastings Biological Field Station of the University of California. Hastings is located in the Santa Lucia mountain range in Monterey County, California.

This station is a collaboration among Hastings, the Berkeley Seismological Laboratory, and the USArray component of the Earthscope program. The station was installed by USArray personnel in July 2004 and is sending data to the Array Network Facility and to BSL.

Geology:
TBD

Vault/Borehole conditions:
The HAST installation is based on the USArray vault design.

Operation Notes: (may not be current)
This section summarizes major changes in equipment or in instrumentation at HAST.

Noise Characteristics:
The figures below are cumulative plots of power spectral density (psd) determined from the broadband channels. In each figure, the vertical component psd is plotted with blue diamonds, the north component psd with red squares, and the east component psd with green circles. The results are presented in the 5 different frequency bands, and the USGS/Albuquerque low noise model is plotted as a dashed line in each. The PSD units are in dB (decibel) relative to 1 (m/s**2)**2/Hz. The current annual plot is updated weekly.

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.
