LocationARC was located on the campus of Humboldt State University, in cooperation with the Geology Department. The site was established in 1948 with the installation of Sprengnether sensors. Wood-Anderson seismographs were installed in 1952 and operated until 1993. The digital broadband equipment was installed in 1992.
The site was relocated in 2001 to station JCC.
NetworkBK (Berkeley Digital Seismic Network)
Vault/Borehole ConditionsThe instruments are sited on the ground floor of Founders Hall at Humboldt State University. The digital instrumentation is located on the same concrete pier as the Wood-Anderson seismometers, in a room at the northwest corner, which is isolated from the hallway via two doors. The seismometers are thermally insulated with 4" of polyurethane foam. An adjoining room contains the datalogger and supporting equipment.
