Location:
Site is located on Ramage Ranch, private property in the Central California Coast Ranges north of San Luis Obispo, CA.

This station is a collaboration between the Berkeley Seismological Laboratory, and the USArray component of the Earthscope program. The station was installed by USArray personnel in June 2004 and is sending data to the Array Network Facility under the station name V04C and to BSL.

Geology:

Vault/Borehole conditions:
The RAMR 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 RAMR.

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.
