CASCADES VOLCANO OBSERVATORY WEEKLY UPDATE
U.S. Geological Survey
Friday, September 16, 2022, 10:26 AM PDT (Friday, September 16, 2022, 17:26 UTC)

CASCADE RANGE (VNUM #)
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 Baker, Mount Rainier, Mount St. Helens, Mount Hood, and Newberry, consistent with background seismicity levels at each volcano. Field crews traveled to Mount Rainier to begin installing new geophysical monitoring sites and perform maintenance on existing infrastructure. Efforts were delayed due to suboptimal weather conditions but will continue next week.

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.
