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 ]
After successfully using seismic activity to predict the 1980 Mt. St. Helens eruption, monitoring was expanded to other Cascade Mountains volcanoes. The PNSN, in conjunction with the Cascades Volcano Observatory of the USGS, now monitors seismicity at all the Cascade volcanoes in Washington and Oregon.

A “fascinating” eruption is approaching as a sleeping giant underwater volcano stirs with seismic activity near America’s west coast. The seismic activity of Axial Seamount, a submerged ...
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 ...
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 .
A national volcano data center will coordinate activities among the observatories. [2] A watch office will be operational 24 hours a day, 7 days a week. [ 11 ] In addition, the USGS will set up a grants program to support research into techniques for monitoring and analyzing volcanic activity.
Gardner at Mount St. Helens in 2004. Cynthia A. Gardner is an American geologist and volcanologist noted for her work on Mount St. Helens. [1] [2] She was the acting Scientist-in-Charge (SIC) of the Cascades Volcano Observatory during the 2004 volcanic reawakening at Mount St. Helens, and officially served as SIC from 2005 to 2010—the first female to fill the role.
