The California Volcano Observatory (CalVO) is the volcano observatory that monitors the volcanic and geologic activity of California and Nevada. It is a part of the Volcano Hazards Program of the United States Geological Survey, a scientific agency of the United States government.[2]

Originally, the volcano observatory was known as the Long Valley Observatory which monitored volcanic activity east of the Sierra Nevada in Mono County, California which included Long Valley Caldera, Mammoth Mountain, and the Mono–Inyo Craters.

In 2012, the Long Valley Observatory was integrated into the new California Volcano Observatory based in Menlo Park, California which covers the entire states of California and Nevada, this includes the southern Cascade Range volcanoes in the state of California which were previously under the jurisdiction of the Cascades Volcano Observatory.[3]
