Some news for a sleepy Monday: Mt. Hood in Oregon. The ash from Eyjafjallajökull is, once again, causing significant airspace closure over northern Europe – close of 1,000 flights today. However, much of the closures are fairly short-lived, but that isn’t keeping people happy. The eruption hasn’t actually changed much, just that the winds are…

I an in the home stretch for grading exams, so just a quick update for today: The evidence of floods from the Eyjafjallajökull eruption, taken on May 1, 2010 by Dr. Joe Licciardi. Airports now as far south as Spain, Morocco and the Canary Islands are facing closures due to the Eyjafjallajökull ash. The latest…

A view of the steaming Mt. Etna, taken on April 8, 2010 by Dr. Boris Behncke. Eruptions reader and member at Italian National Institute of Geophysics and Volcanology in Catania, Dr. Boris Behncke, has been keeping many of us appraised on the goings-on at Mt. Etna. A series of earthquakes occurred on April 2-3 along…

Reawakening Redoubt?

News comes out of Alaska that a small earthquake swarm has begun under Redoubt. This is the second such swarm since the volcano’s 2009 activity ceased. Most of the seismicity appears to be near…

A shot from the Hekla webcam showing the glow from the eruption of Eyjafjallajökull that started March 20, 2010. Quick note, but for those of you who have been following the seismicity at Eyjafjallajökull in Iceland, there is news from Iceland that an eruption has started. I will post more details as I can find…

Leaving for Death Valley tomorrow – I’ll be sure to take some pictures of Ubehebe Crater and the volcano at the Mirage. This will likely be the last new post until about a week from now, but look for the Erta’Ale Volcano Profile, maybe a new Mystery Volcano Photo and I’ll leave a thread open…

Did I mention its a busy week? The lava lake at Erta’Ale in 2008. Image courtesy of Stromboli Online. Our Icelandic saga continues, with more earthquakes and more speculation/information on the parts of Eruptions readers. Keep up the discussion – I’ll be fascinated to see who turns out to get closest to what actually happens,…

Eyjafjallajökull, an ice-capped volcano in Iceland that last erupted in 1823. We talked a few weeks ago of signs that there were increasing signs that an eruption could occur on Iceland – increased seismicity on the Reykjanes Ridge suggested that magma might be on the move. Now, we have two pieces of evidence that we…

Some news for a busy Tuesday: The crater at Poas volcano in Costa Rica, taken February 25, 2010. Image courtesy of OVSICORI by Federico Chavarria. After the MSNBC debacle, it is nice to see some good articles on why the Chilean earthquake was overall less disastrous than the Haitian earthquake, why the tsunami wasn’t as…

The rhyolite domes of Chaiten in Chile in an undated photo. Note how much of the previous Chaiten Caldera has already been filled by the new domes that started after Chaiten erupted in May 2008. CNN International has a report that the National Emergency Office (ONEMI) in Chile has reinforced the “red alert” status of…
