The David A. Johnston Cascades Volcano Observatory (CVO) is a volcano observatory in the US that monitors volcanoes in the northern Cascade Range. It was established in the summer of 1980, after the eruption of Mount St. Helens . [ 2 ]
It is monitored by the Pacific Northwest Seismic Network and the Cascades Volcano Observatory via a seismic station on the southwest flank of the mountain. [47] During the month of September 2024, the U.S. Geological Survey Cascades Volcano Observatory recorded six earthquakes ranging in magnitudes 0.9 to 2.0. With a normal rate of one ...

Twelve volcanoes in the arc are over 10,000 feet (3,000 m) in elevation, and the two highest, Mount Rainier and Mount Shasta, exceed 14,000 feet (4,300 m). By volume, the two largest Cascade volcanoes are the broad shields of Medicine Lake Volcano and Newberry Volcano, which are about 145 and 108 cubic miles (600 and 450 km 3) respectively.
A volcano observatory is an institution that conducts research and monitoring of a volcano. Each observatory provides continuous and periodic monitoring of the seismicity , other geophysical changes, ground movements, volcanic gas chemistry, and hydrologic conditions and activity between and during eruptions .
