2009: The Volcanic Year in Review

Here it is, my attempt to recap a year’s worth of volcanic events. By no means is this supposed to capture every event, but rather the highlight/lowlights and what most captivated me during 2009. I’ll be announcing the winner of the 2009 Pliny for Volcanic Event of the Year tomorrow. Waimangu Geothermal Valley in New…

Looks like last night was busy, volcanically speaking. Eruptions readers noted that VAAC warning of ash from both Mayon (to 10,000 feet / 3.0 km) and Bezymianny (to 32,000 feet / 10 km) were issued {hat tip to Chance Metz for the updates}. Here is some more news on these ongoing events: Mayon erupting in…

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…

Plumes a-poppin’!

Maybe I should just apologize right here and now for that title, but dang, I liked it. Anyway, I’ve seen a lot of plume images cross my browser/inbox over the last day, so I thought I’d post a few of them. Soufriere Hills, Montserrat The renewed activity at Soufriere Hills has produced a bounty of…

An ash plume from Soufriere Hills on Montserrat, taken from the ISS on October 11, 2009. If you ever wonder what might happen to the U.S. if a large volcanic eruption, lets say from Rainier or Long Valley or Shasta, occurred, you can look at the island of Montserrat for some of the potentials problems.…

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…

All the news to start the week: Galeras with a grey ash-and-steam plume behind Pasto, Colombia. Well, after my article on Friday about Colombian volcanoes, Galeras must have decided it was left out. The volcano has been placed back at alert level Orange/II (eruption in days to weeks). An increase in seismicity and sulfur dioxide…

There has been news over the last few days of a number of volcanoes in Colombia, so I thought I’d try to gather it up here: The steaming summit of Nevado del Huila in Colombia Nevado del Huila has been ramping up its ash emissions, potentially pointing towards new eruptions from the crater dome. The…

I’ll be giving a talk this afternoon here at Denison on rhyolite generation, so I might be a little brief this morning. Undated image of Mayon in the Philippines. The province of Albay in the Philippines is on alert for both a typhoon and a volcano (that country seems to be hit with that
