- Location:
-
Site is located on Ramage Ranch, private property
in the Central California Coast Ranges north of
San Luis Obispo, CA.
This station was installed in June 2004 by USArray personnel as a collaboration with the Berkeley Seismological Laboratory, and was part of the USArray component of the Earthscope program. When the Travelling Array left California in 2007, the BSL adopted this station. It has been operating as a BDSN station since September 2007.

The RAMR installation is based on the
USArray
vault design.

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.
