Mauna Loa fire fountains in 1984 For those of you looking for some non-Redoubt-related volcano news, you can take a look at the 25th anniversary of the last eruption at Mauna Loa (there is some nice video footage provided by KHNL if you follow the link). By no means is this volcano “dormant”, but rather…

Image by AVO/USGS/Game McGimsey, March 23, 2009 Redoubt has simmered down some today with no new eruptions since yesterday evening. AVO’s field crew not only fixed the Hut webcam, but also spotted massive lahar deposits (see above) in the Drift River valley that traveled 35 kilometers downstream and have officials on local and national levels…

The Hut webcam at Redoubt that has a great view of the hydrothermal vents near the 1989-90 domes – and the area where the current eruption is likely to be sourced – is back online. So far, we can see what looks like lahar deposits on the lower left-hand flanks of the volcano in the…

The Anchorage Daily News has a report that 16 Alaskan representatives got stuck in Anchorage after the eruption started.

ADN also have…

Redoubt Erupts!

Mt. Redoubt in March 2009, prior to erupting At ~10:30 PM (Alaskan Time) last night, Mt. Redoubt erupted. AVO and the Anchorage VAAC issued a Red Alert for ash as high as 50,000 feet (15,000 meters) around the volcano. Information is scarce about the exact nature of the ash cloud because of the fact that…

Seismicity has increased dramatically at Redoubt in Alaska over the last 24 hours, so AVO has put the volcano back on Orange/ Watch status. They say the tremors being felt now could be signs to an impending eruption (days to weeks), especially after the other events of the past week. Stay tuned! (Pardon the briefness,…

FEMA and volcanoes

So, as I am apt to do from time to time, I was wandering the interweb and stumbled across the FEMA (Federal Emergency Management Agency) for Kids website. Naturally, I thought, what do they have to say about, oh, I don’t know, volcanoes. Well, was I in for a doozy! FEMA, in its infinite wisdom,…
