Mount St. Helens Volcano - Current Update

Friday, October 31, 2014 9:44 AM PDT (Friday, October 31, 2014 16:44 UTC)

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 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, and Crater Lake in Oregon.

Recent Observations: The onset of winter storms, especially in the past week, has generated a lot of noise on seismic instrumentation in the Cascades. Although seismic activity at most volcanoes remains at background levels, the onset of these storms has induced notable minor seismic activity at Mount Rainier. A number of repetitive, very-small-magnitude quakes, commonly observed at Rainier once winter storms appear, began a couple of weeks ago and continue. Ongoing research attributes these quakes to slip along the bases of the volcano’s glaciers, not to volcanic activity. Recent winter storms have also raised the levels of regional rivers, and at this time of year heavy rains on volcanoes cloaked in minimal snowpack can trigger debris flows and landslides. Anyone working or recreating near river channels should be mindful and cautious of potentially rapidly changing conditions.

This is a static image of Mount St. Helens, taken from the Johnston Ridge Observatory. The Observatory and VolcanoCam are located at an elevation of approximately 4,500 feet, about five miles from the volcano. You are looking approximately south-southeast across the North Fork Toutle River Valley. The VolcanoCam image automatically updates approximately every five minutes.
