Volcanic Descriptions



Activity Update: All volcanoes in the Cascade Range are at normal levels of background seismicity. These include Mount Baker, Glacier Peak, Mount Rainier, Mount St. Helens, and Mount Adams in Washington State; Mount Hood, Mount Jefferson, Three Sisters, Newberry Volcano, and Crater Lake, in Oregon; and Medicine Lake volcano, Mount Shasta, and Lassen Peak in northern California.

Recent Observations: No unusual geologic activity was apparent at any of the Cascades Volcanoes during the week. Volcano seismicity remained at background levels. Hydrologic field teams collected stream data and serviced monitoring stations in Mount St. Helens drainages.

The U.S. Geological Survey and University of Washington continue to monitor these volcanoes closely and will issue additional updates and changes in alert level as warranted.
