The USGS California Volcano Observatory (CalVO), headquartered in Menlo Park CA, replaces the former Long Valley Observatory (LVO), which was established in 1982 to monitor the restless Long Valley Caldera and Mono-Inyo Craters region of Eastern California.

The USGS California Volcano Observatory (USGS CalVO), with staff and data center in Menlo Park, CA, has responsibility for monitoring all volcanoes in the states of California and Nevada. During periods of quiescence, CalVO watches for signs of unrest, conducts research related to volcanic hazards, and provides long-term hazard assessments to government agencies, private industry, non-governmental organizations, educational institutions, and the public. As a volcano moves from quiescent to active, CalVO will issue hazard alerts, providing timely information as volcanic activity ramps up, and, as importantly, as the volcano returns to quiescence. This information is communicated through telephone call-down procedures and written notices.

Scientists at the five USGS volcano observatories research, monitor, and assess hazards at United States volcanoes and provide activity notifications and eruption warnings in the event of volcanic crises. The volcano monitoring responsibility of CalVO includes all potentially active volcanoes in California and Nevada. The Cascade Volcano Observatory (CVO), CalVO’s sister observatory in Vancouver, WA, oversees efforts at all potentially active volcanoes in Oregon, Washington, and Idaho. CalVO and CVO share scientific expertise, administrative staff, and equipment, ensuring a strategic and cost efficient program of volcanic hazard mitigation.
