Eruptions reader Ross was very right in pointing out that something is up at Redoubt. The Alaska Volcano Observatory has put Redoubt on orange alert for aviation and suggest that an eruption could occur with "hours to days". The most recent update from AVO says that a recent overflight of the volcano done this afternoon shows no evidence that an eruption has started, but steam and sulfur output has increased. Meanwhile, seismicity at the volcano is also well above background. In all, it sounds like the Aleutians might have yet another volcano erupting if these signs continue.
