Mount St. Helens Volcano - Current Update


CASCADES VOLCANO OBSERVATORY
Friday, September 19, 2014 10:21 AM PDT (Friday, September 19, 2014 17:21 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: A short 10-minute-long burst of small deep (~10 km, or ~6 miles) low-frequency events occurred at Newberry on the evening of September 17th this week, similar to another short-lived sequence that occurred at Newberry on 07/31. Such events occur on occasion at most monitored Cascade volcanoes, particularly Mounts Baker, Rainier, and Hood, and although unusual, are considered to be part of normal background seismic activity at these volcanoes. Field crews conducted hydrologic and geologic studies at Mount St. Helens and Mount Shasta. A new seismometer and GPS system was installed at Mount Hood this week.
