| Description: | I started this blog after getting frustrated with the news reports of volcanic eruptions. Most of them get the information wrong and/or are just sensationalistic. I will try to summarize eruptions as they occur, translate some of the volcanic processes that are happening and comment on the reports themselves. |

Monday Musings: Gaua evacuations, more activity at Soufriere Hills and the destructive force of Toba
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 -

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 large eruption was needed to produce such an ash column (and you'd be right). Then, no news. Nothing.

Q&A: Dr. Boris Behncke answers your Italian volcano questions, Part 2
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 foreseeable future? Or is the volcano slowly "dying" although the last eruption ended in July 2009 has been one of the longest ever recorded? 2. Not really related to volcanism, but close: does INGV

Large eruption at Karkar in Papua New Guinea?
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 plume reached a height of 45,000 ft. A magnitude 5.1 earthquake hit 90 km SSE of Karkar volcano 7.5 hours before the eruption. I don't know too much
