Thar she blows!

Mount Redoubt blew its lid last night and continues to erupt today, according to the Alaska Volcano Observatory (AVO), which has logged at five eruptions so far. The first was at 10:38 last night Alaska time (2:38 a.m. EDT); the next one occurred 24 minutes later followed by three more eruptions this morning at 12:14, 1:39 and 4:37.

Plumes from the volcano, which is about 103 miles southwest of Anchorage, rose 50,000 feet into the air, according to the Associated Press. The National Weather Service issued an ashfall advisory through noon today, recommending that area residents seal their windows and doors to prevent ash from getting indoors.

AVO officials also warned of potential mud flows and flooding from melting glaciers, the Anchorage Daily News reported. 

The observatory raised the volcanos status to code red yesterday, which means an eruption is imminent or underway. It had raised its status from yellow (an advisory indicating elevated unrest) to orange (a watch or warning status suggesting heightened unrest), a week ago after logging increased seismic activity.

AVO's John Powers told the Anchorage Daily News that the eruptions could persist for a while, noting that in 1989 and 1990 the volcano remained active for five months.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
