UPDATE: See some amazing images of the recent eruptive activity over on Stromboli Online. {Hat tip to the Volcanism Blog via Eruptions reader CK.} One event that didn’t eat much coverage over the weekend, at…

The weekly volcano report, brought to you by our friends at the Smithsonian Global Volcanism Program and the U.S. Geological Survey. Highlights (not including Mayon, Nyamuragira and Turrialba): Eruptions continue at Piton de la Fournaise on Reunion Island – heck, this would be the volcano news if it wasn’t for all these other, more explosive…

Mayon Update for 12/28/2009

Lava flows from Mayon, taken December 23, 2009. Volcano news over the holidays this year is still focused on Mayon in the Philippines. We’re reaching almost a month since the volcano starting showing signs of a major eruption, but no “big one” yet. Lava flows, ash and block-and-ash flows are continuing to be issued from…

Mayon eruption update for 12/16/2009

Lava on Mayon, December 2009, with Legazpi City in the foreground. The mainstream media has picked up on the activity at Mayon – I’ve seen it splashed across CNN, FoxNews, ABC, BBC and others. Most of the coverage has been decent, however, I do worry when I see that people have found Eruptions using search…

It’s the last week of classes and it’s also AGU (which I will be missing for the first time in 5 years). If you happen to be at the big meeting in SF and hear something you think we’d like to hear, feel free to drop me a line or leave a comment so we…

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 latest of volcano news from around the world, brought to you by the USGS and Smithsonian Institute Global Volcanism Program (and especially Sally Kuhn Sennert!) Highlights this week include: Karangetang in Indonesia produced a couple 3 km/10,000 foot steam-and-ash plumes according to reports from pilots. Soufriere Hills on the island on Montserrat has had…

A pile of new volcano images

Sometimes it is hard to keep up with the mountain of remote sensing (or not so remote) images that get released on the internet. Over the last few days, the NASA Earth Observatory has released a bunch of images/videos of current eruptions, so I thought I’d round them all up here for you to peruse.…

I missed the weekly report last week (sorry), but here is the new USGS/SI volcano activity report. Highlights include: Shiveluch in Kamchatka is still erupting away, producing ~7 km / 20,000 foot ash columns as the lava dome grows. There has also been pyroclastic flows spotted emanating from the new lava dome. There was a…

Monday is here again already … A pyroclastic flow from Soufriere Hills heading towards the ocean. Note the large volcaniclastic debris fan being formed by repeated flows. Dated March 2006. The “Science Advisory Committee” at Montserrat in the West Indies suggests that the current eruption of Soufriere Hills on the small island could be drawing…
