Seismic Monitoring in the Long Valley area
Seismic network
Earthquakes occurring in the Long Valley area are recorded by a network of 18 seismic stations within the caldera and an additional 20 stations within a distance of 50 km beyond the caldera boundary. These stations comprise parts of both the Northern California Seismic Network (NCSN) operated by the U.S. Geological Survey in Menlo Park, California (stations names ending in M), and the Nevada seismic network operated by the University of Nevada, Reno (station names ending in R). The signals from the combined stations are shared by both networks. The signals telemetered to USGS headquarters in Menlo Park are processed along with data from the rest of the Northern California Seismic Network and archived on a mass storage device at the University of California, Berkeley - USGS data center.
