|(11) Volcanic Activity Summary:||The Alaska Volcano Observatory is lowering the Aviation Color Code to YELLOW and the Alert Level to Advisory for Mount Redoubt. The new magma beneath the volcano does not show any signs of upward movement at this time. The volcano remains restless with abnormally high gas emission rates and melting of the summit glacier still evident. It is still quite possible, though far from certain, that the current volcanic unrest at Mount Redoubt could result in an eruption. Also, this unrest could persist for many months to a year or more and not lead to an eruption. During this unrest, it is possible for unrest at the volcano to change rapidly, advancing from relatively low levels to eruption in time periods as short as 24 hours or less.
AVO will continue to monitor Redoubt closely, but will no longer be formally staffed 24 hours per day.
