California Volcano Observatory, Geological research facility in Menlo Park, California, United States
The California Volcano Observatory is a research facility in Menlo Park that monitors volcanic activity across California and Nevada through a network of sensors and instruments. The station continuously collects data on earthquakes, gas emissions, and ground movements at several active volcanic areas.
The facility was founded in 2012 and replaced the Long Valley Observatory, which had monitored the Long Valley Caldera and Mono-Inyo Craters since 1982. This establishment expanded monitoring capabilities to more volcanic systems across the region.
The observatory maintains public education programs to inform California residents about volcanic hazards and the geological characteristics of their region.
The facility is accessible during business hours, and visitors can learn about ongoing research and its importance to public safety. It is recommended to check in advance since hours vary and some areas may not be open to the public.
The observatory monitors sixteen young volcanoes across California, seven of which contain partially molten rock that generates regular earthquakes and gas emissions. These geologically active systems offer researchers rare opportunities to observe volcanic processes in real time.
