U.S. Geological Survey
Friday, September 9, 2022, 9:26 AM PDT (Friday, September 9, 2022, 16:26 UTC)


CASCADE RANGE VOLCANOES
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

Activity Update: All volcanoes in the Cascade Range of Oregon and Washington are at normal background levels of activity. 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, and Crater Lake in Oregon.

Recent Observations: Over the last week earthquakes were located at Mount Rainier, Mount St. Helens, and Mount Hood, consistent with background seismicity levels at each volcano. USGS workers were at Mount Rainier over the past week installing a new monitoring station.

The U.S. Geological Survey and Pacific Northwest Seismic Network (PNSN) continue to monitor these volcanoes closely and will issue additional updates and changes in alert level as warranted.
