Well, after all that, apparently Redoubt is not quite done.
Summary: Mt. Redoubt showed an increase in activity (new fumarolic and generally increased gas emissions, elevated seismicity) a few months ago, and kept it up for a while with no actual eruption. The activity suggested magma was on the move, so it was monitored closely. The media got very excited. The volcano stayed in something of a “holding pattern” for a few more weeks, and then last week it calmed back down – although the new degassing continued, the seismicity decreased.
But it was just tricking us, or maybe it liked the attention. Yesterday it had new tremors:
…and put out a 15,000′ steam plume:
…with no ash ash that may be old, so technically not necessarily an eruption. The internet is suggesting a phreatic blast, which would make sense. But eruption or not, it’s a large burst in activity nonetheless, bumping it back up to aviation code Orange and alert level Watch. More details at Eruptions and the Volcanism Blog.
