Eruptions

Archives for November, 2009

Back to work after Thanksgiving Break … lets clean up a few news items I missed trying to figure out the non-eruption of Karkar. Undated photo of the summit area of Gaua, Vanuatu. There was an actual eruption – or, more correctly, a continued eruption – of Gaua in Vanuatu. The current activity has prompted…

The mysterious non-eruption of Karkar

Last week, I reported that Karkar in Papua New Guinea had erupted. This was based on reports from Volcano Live and from the Darwin VAAC that said the volcano had produced at least 1, maybe 2, ~13 km / 45,000 foot ash columns. That is not a trivial ash column – you would think a…

Here is Part 2 of the Q&A with Dr. Boris Behncke. You can also check out Part 1. Undated image of Stromboli in eruption. (Shirakawa Akira) 1. Would a large scale eruption (VEI 5 or greater) of Mt. Etna like the ones occurred in 122 BC and 1500 BC (disputed) be possible again in the…

Karkar volcano as seen from space. Eruptions reader The Bobs left a note mentioning that there may have been a ‘significant’ eruption at Karkar in Papua New Guinea. The only place I can find information is John Seach’s Volcano Live: An eruption occurred at Karkar volcano at 6:39 pm on 25th November 2009. The eruption…

First off, I want to thank Dr. Behncke for taking the time to answer your questions – and also, thank you to all who sent him some thought-provoking questions. In fact, the questions and answers take up about 12 pages of text, so the Q&A will be divided into two parts. If you want to…

Back from Iowa, time for some volcano news. Look for the answers to your questions for Dr. Boris Behncke to get posted later this week. (And thanks for all the comments and kind words in the Open Thread. I’ll start thinking about how to implement a lot of these in the next few weeks). Undated…

Eruptions suggestion thread

I’ll be busy for a couple days when I’m off at University of Iowa, so I thought I’d leave this thread available for you to talk. Specifically, I’m interested in what you might be interested in seeing (or not seeing) on Eruptions. I’ve tried a number of features (Mystery Volcano Photo, Q&A, Volcano Profiles) –…

The latest news from the USGS/Smithsonian Global Volcanism Program Weekly Volcano Report … Highlights (not including Mayon) include: Strombolian eruptions and small pyroclastic falls at Arenal in Costa Rica. 3 km / 10 000 foot ash plume from Bagana on Bougainville Island in Papua New Guinea. Rumbling noises, ~4.5 km / 14 000 foot ash…

Mystery Volcano Photo #15

It has been a slow week for volcano news (and a busy week for me), so I apologize for the abundance of MVPs this week. I’ve tried to find a good one in the many images submitted to me by Eruptions readers, and #15 is just one of those photos. If you have images you’d…
