The clock is ticking for the new dome growing at Redoubt to collapse. What will happen if/when it does collapse? Good question!

Most likely, the following will occur:
First, extrusion of lava will cause…

Speaking of anniversaries, this weekend is the one-year mark for the Chaiten eruption (in spanish) in Chile, the first eruption at the volcano in ~9,000 years. Yes, indeed, the rhyolite eruption that caught most everyone by surprise is still…

For those of you who might not be paying as close attention to Redoubt now as in the past, this is the latest from AVO:
Redoubt's 2009 eruption continues and appears to be gaining intensity. Seismic activity has increased markedly in the last 24 hours, showing stronger volcanic tremor and more…

Sometimes it is hard to appreciate how many volcanoes lie within Indonesia. However, within the last few weeks, no less than four Indonesian volcanoes have been put on alert to eruption or shown increased signs of activity - Slamet,…

Happy Birthday, Eruptions!
Well, this definitely snuck up on me, but today marks the one-year anniversary for Eruptions! On May 1, 2008, I started this little blog and if anyone told me that a year later I'd be paid for the gig and getting 50,000 views a month, I would have called them nuts.
So,…

It has been quite some time since I talked about Redoubt, mostly because the volcano has been in the "slow extrusion of a dome" mode that has not generated much beyond impressive…

Volcano monitoring. Image courtesy of the USGS.
Last night I had the opportunity to see a talk given by YVO Scientist-in-Charge Dr. Jake Lowenstern as part of the Volcanological Society of Sacramento meeting and he gave a great talk on the state of volcano monitoring today in the U.S. He laid out…

The weekly USGS/SI roundup is out. Highlights (beyond Slamet) include:
Explosions (some heard 25 km away) and incandescent blocks that started fires at Galeras, Colombia.
Ash and tephra being thrown tens of meters into the air and a 4-m tall spatter cone being built at Pacaya, Guatemala
Also in…

Descabezado Grande, Chile showing increased fumarolic activity in 2009.
Well, if they didn't have enough already between Llaima and Chaiten, another volcano in southern Chile has started erupting. Descabezado Grande (roughly translated: "The Big Beheaded One") has erupted or is showing of eruption…

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…

Few websites offer so many unique views of active volcanism than the NASA Earth Observatory. That is why I'd like to wish the EO a happy 10th birthday. The website first came online April 29, 1999…

One of the best resources for volcanism on the planet needs someone to run it:
National Museum of Natural History, Smithsonian Institution,
Washington D.C. anticipates hiring a distinguished scientist to become
the Director of the Global Volcanism Program and to conduct a research
program in…

Shiveluch volcano in Russia. Image courtesy of KVERT.
Over this past weekend, Shiveluch in Kamchatka experienced a plinian eruption, producing a 7-km / 23,000 foot ash column. The NASA Terra satellite caught a great image of the ash plume over the snowy landscape of the Kamchatkan Peninsula on…

Mt. Slamet, Indonesia, with agricultural fields in the foreground.
I'll be brief, mostly because I'm still lost in a haze of jetlag and allergies, but ...
Mt. Slamet on the island of Java in Indonesia is showing signs of a "major eruption". Preparations have begun by the Indonesian government to…

Back in the days when Eruptions was on Wordpress, I held a vote about what volcano should be the next to be profiled on this blog. The winner was Mt. Hood in Oregon, and after much waiting, the profile is here. I will actually be out of town until Monday doing some house shopping in this little…

Satellite image of the island of Tenerife with the main vent of the volcano (El Teide) in the central part of the island.
I will be out of town for the next few days, so I thought I'd leave this thread for breaking volcano news that any of you Eruptions readers notice.
However, I couldn't pass up…

UPDATED 3:30PM Pacific: The Associated Press has put up some silent video of the lava flows reaching the ocean at night
The Geophysical Institute in Ecuador is reporting that the eruption at Fernandina in the Galapagos has intensified over the last 24 hours. Heck, the image accompanying the report…

Has a week gone by already? It is time for another USGS/Smithsonian GVP Weekly Volcano Activity Report.
Highlights (beyond Fernandina, Pagan and Redoubt) include:
A new underwater eruption at NW-Rota 1 in the Mariana Islands.
Increasing seismicity and incandescence from the rhyolite domes forming…

Mt. Baker in Washington. Image taken by John Scurlock.
Eruptions reader Robert Somerville brought to my attention the Mount Baker Volcano Research Center, a "clearinghouse for research on Mt. Baker" in Washington state. The center is a non-profit organization that is affiliated with the Geology…

The latest reports about the ongoing eruption at Fernandina are both coming and going. Reports from officials in the Galapagos National Park suggest that the eruption was become more intense (in spanish), while later…

Well, after lamenting the slow volcano news, things are beginning to pick up again. Beyond the news of a potential increase in activity at Anak Krakatau, there are a few other newsworthy bits that have come up:
Mt. Kerinci in Indonesia
Mt. Kerinci in Indonesia is showing signs of eruption. The…

Anak Krakatau erupting in 2007.
There is a report out tonight that activity might be increasing at Anak Krakatau in Indonesia, however, it is unclear whether it is actually increasing or not. People are evacuating the coastal area of the Sunda Strait to Bandarlampung in fear that a major eruption…

As of late, a number of comments have been eaten by the SB spam filters. Mostly, they are longer comments with hyperlinks. I try to check the spam folder to catch such incorrectly identified comments, but if you notice your comment not showing up in the discussion, shoot me an email and I can check…

It has been rather quiet on the volcano-front in the last week. Redoubt and Llaima (in spanish), after a few weeks of intense eruption, are both back on Orange Alert. News of the eruptions from Hunga Tonga Hunga Ha'apai and Fernandina is rather sparse in the details. The news of volcanism in 2009…

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.

Eruptions reader Brian just pointed out that AVO has posted a new webcam (well, a redirectly webcam) for the volcano and I thought it deserved its own post. This new angle gets you right up to the new dome…

Fissure vent eruption from Fernandina in the Galapagos Islands.
In news that comes as a surprise to no one, the current eruption on Fernandina in the Galapagos is having some adverse effect on the wildlife in the Pacific archipelago. Numerous dead fish and sea lions have been seen in the ocean…

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…

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…

Busy day so I probably won't get to update much as we're busy hosting Dr. Charlie Bacon, geologist for the USGS, here at UC Davis today. Dr. Bacon has written some seminal papers in his career and is probably the foremost authority of the evolution of Crater Lake/Mt. Mazama (speaking of which, >…
