- Location:

The MNRC site is on property owned and formerly
operated by Homestake Mining Company as a surface gold mine.
The
geology of the area
is extremely varied and complex. With the conclusion of mining operations, the property
will be managed by UC Davis as the
McLaughlin Reserve
(part of the University of California Natural
Reserve System.
The seismographic vault is the first new research project on the reserve. The site is located
approximately 20 kilometers east of the town of Lower Lake,
California in an area of Franciscan sandstone.
Support for MNRC was provided by the Governor's Office of Emergency Services as part of the California Integrated Seismic Network.

Franciscan sandstone
- Vault/Borehole conditions:
-
A steel and concrete vault from a shipping container
similar to those found at stations JCC,
PKD, and HOPS was
constructed. Power and telephone lines were trenched approximately
300 meters to the site. Because of the remoteness of the site,
digital telephone data circuits are not available. Telemetry was
established in spring 2004 using a radio network that brings the
data down to Napa and into the frame-relay network.

Several tools provide access to SEED format data at the NCEDC, both in terms of querying the archives and allowing data requests.- Querying the archives
- Requesting data by channel and time
- Requesting data by event
Help on using these tools is available.
