USGS Volcano Hazards Program Volcano Update


CVO update page and observatory web site


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: A swarm of small earthquakes occurred on the south side of Mount Hood on February 18 in an area that experienced a similar swarm the week before. Such earthquake swarms occur a few times per year and represent no change in volcanic activity.

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.
