USGS Volcano Hazards Program Volcano Update
CVO update page and observatory web site
Activity Update: All volcanoes in the Cascade Range of Oregon and Washington are at normal levels of background seismicity. These include Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams in Washington State; and Mount Hood, Mount Jefferson, Three Sisters, Newberry Volcano, and Crater Lake, in Oregon.
Recent Observations: Seismicity in the Cascade Range remains at background levels. For the past month, turbidity levels in Loowit and Step Creeks have been elevated. Field crews worked at Mount St. Helens and Crater Lake this week. At Mount St. Helens, crews measured North Fork Toutle River suspended sediment and performed maintenance on turbidity sensors. Upgrades were made to seismic and GPS stations at Crater Lake.
The U.S. Geological Survey Cascades Volcano Observatory and the University of Washington continue to monitor the Washington and Oregon volcanoes closely and will issue additional updates and changes in alert level as warranted.
