Cascade Range Volcano
45°36'36" N 122°30' W, Summit Elevation 0 ft ( m)
Current Volcano Alert Level: NORMAL
Current Aviation Color Code: GREEN

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: A volcanically uneventful week along the Cascade Range was faintly punctuated by a very small Mt. Hood earthquake (0.6M) at 6:20am (PST) today. This is considered to be within the range of typical 'background level' seismicity beneath Mt. Hood.
