CASCADE RANGE VOLCANOES

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: Monitoring systems show that activity at Cascade Range volcanoes in Washington and Oregon remained at background levels throughout the week. A few small earthquakes were recorded at Mount Rainier, Mount St. Helens, and Mount Hood, which is not unusual. All other measurements were within normal ranges.


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.
