Volcanic Descriptions



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: Activity at all Cascade Range volcanoes remained at background levels, as measured by seismic, GPS, and, where available, tiltmeter data. There have been some small earthquakes at Mount Rainier, but of a sort familiar to seismologists and not indicative of volcanic unrest.

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.

For other inquiries please call 360 993-8973.
