Mount St. Helens Volcano - Current Update
CASCADES VOLCANO OBSERVATORY
Friday, December 6, 2013 9:03 AM PST (Friday, December 6, 2013 17:03 UTC)
CASCADE RANGE VOLCANOES
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: Those watching seismic records for Newberry volcano will recognize small earthquakes on the CPCO station. These are ice quakes, a consequence of icing across the two caldera lakes, Paulina and East. The lakes's surfaces rumple and crack as the ice deforms. Newberry's ice quakes were spotty as early as November 24 but have occurred frequently this past week as the entire Pacific Northwest enters an episode of record-setting subfreezing temperatures, even in maritime areas.
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 updates and changes in alert level as warranted.
