Eruptions Mailbag for June 2009

Chaiten in Chile erupting in January 2009. Even after over a year of activity, Eruptions readers are still captivated by the volcano. Thanks for sending me your questions about volcanoes and volcanism. I’ll try to tackle some hear – but as always, keep the questions coming! Send them to For those of you who have…

Monday Mulligans

I won’t try to recap all the news from last week, but I did notice a few articles from this weekend worth noting: The Big Obsidian Flow at Newberry Volcano. This rhyolite lava flow erupted at ~1,300 years ago. Geologists in Greece are keeping an eye on a submarine volcano called Columbus. Apparently a number…

Mount Saint Helens less than 30 seconds after a sector collapse that triggered one of the largest eruptions in the Cascades in the last 500 years. Today is the 29th anniversary of the dramatic eruption of Mount Saint Helens in Washington state. The eruption dramatically changed the landscape around the volcano along with greatly increasing…

Wednesday Whatzits

This is another busy Wednesday for me as the Geology Dept. at UC Davis will be hosting Dr. Jacob Lowenstern, USGS scientist and director of the Yellowstone Volcano Observatory. He will be giving the weekly seminar, along with another talk in the evening at Sacramento State as part of the Volcanological Society of Sacramento meeting…

Friday Flotsam

The weekend is rolling in and I might end up spending most of it in the 90+ degree California weather, so unless something big comes up (volcanically), I’ll leave you with a few news bits.

Mount Pagan in the Mariana Islands erupting on April 15, 2009. Image courtesy of the NASA Earth Observatory. Up until fairly recently, a lot of volcanoes got away with erupting without anyone knowing the better. However, with all the “eyes in the sky” we have these days, even remote oceanic volcanoes get caught in the…

Here’s the latest Global Volcanism Program activity report for worldwide volcanism. Some of the highlights (beyond Fernandina and Llaima) include: Vulcanian-style eruptions at Sakurajima, Japan. And guess what? There is a Sukarajima webcam! {Hat tip to Eruptions reader Jodie Morris for this link}. Strombolian-style explosions and avalanches associated with lava flows at Arenal, Costa Rica.…

Fernandina, Ecuador Fernandina erupting in 2009. UPDATE 4/13/09 at 12PM: The NASA Earth Observatory has posted a nice MODIS image showing the plume from the Fernandina eruption drifting out over the Pacific. We have a few more details on the ongoing eruption at Fernandina in the Galapagos Islands. Officials from the Parque Nacional Galápagos (PNG)…

Goma after the 2002 Eruption of Nyiragongo The activity at Redoubt has captivated a lot of us, but in the grand scheme of things, its eruption are more likely to caused inconvenience and property damage rather than dramatically loss of life (unless something huge and unexpected occurs). However, the same cannot be said if Nyiragongo…

Image courtesy of AVO/USGS by Game McGimsey Following the provided script, Redoubt erupted again last night, producing a 32,000 foot / 10,000 meter ash column that prompted a new ash fall warning for the Kenai Peninsula area. Thus far, though, there have been few reports of major damage being caused by the ash fall. Alaska…
