- Location:
-
The site is located at the Marconi
Conference Center, part of the State of California Parks
system.
The Conference Center occupies the site of Guglielmo Marconi's Marshall Receiving
Station, where signals were received from the first radio transmission across the Pacific Ocean.
MCCM is a cooperative station with the Advanced National Seismic System and was a USArray component of the Earthscope program from February 2006 to November 2007. Support for MCCM was also provided by the Governor's Office of Emergency Services as part of the California Integrated Seismic Network.

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.
