The David A. Johnston Cascades Volcano Observatory (CVO) is a volcano observatory that monitors volcanoes in the northern Cascade Range. It was established in the summer of 1980, after the eruption of Mount St. Helens.[1] Its current territory covers Oregon, Washington, and Idaho. The Cascade range's southernmost reaches extend into Northern California, and Cascade volcanoes south of the Oregon-California border—such as Mount Shasta—previously fell into CVO's jurisdiction. However, as of February 2012, these volcanoes fall under the jurisdiction of the newly formed California Volcano Observatory (CalVO), based in Menlo Park, California which monitors and researches volcanic activity throughout California and Nevada.[2]

The Cascades Volcano Observatory is part of the United States Geological Survey, a scientific agency of the United States government.[3] It is located in Vancouver, Washington in the Portland, Oregon metropolitan area.
