CASCADE RANGE VOLCANOES

Activity Update: All volcanoes in the Cascade Range of Oregon and Washington are at normal background levels of 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. Additionally, GPS data from most of the major volcanoes, and sparse real-time hydrologic and geochemical monitoring, show no anomalous activity.


Recent Observations: Seismicity and deformation at Cascade Range volcanoes in Washington and Oregon remain at background levels. Field crews conducted geologic mapping at Glacier Peak and deployed GPS receivers to update positions of monitoring benchmarks at Mount Baker and Three Sisters.
