Mount St. Helens Volcano - Current Update
CASCADES VOLCANO OBSERVATORY
Friday, July 25, 2014 9:26 AM PDT (Friday, July 25, 2014 16:26 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: Activity at Cascade Range volcanoes has remained at background levels during the past week. This past Wednesday and Thursday evening, the Imaging Magma under St. Helens (of iMUSH) group set off 15 shots for an active seismic experiment to better understand the plumbing system of the Cascades’ most frequently active volcano as well as to better understand how continental crust is formed. The shots purposely created small earthquakes (too small to be felt) that can be seen on the Pacific Northwest Seismic Network (PNSN) webicorder records. Information about the iMUSH experiment and goals are at http://imush.org; for webicorder records visit the PNSN website at http://www.pnsn.org.
