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…

May 18, 2010 marks the 30th anniversary of the dramatic eruption of Mount St. Helens in Washington state. Now, rather than recount the event when the USGS and the Cascade Volcano Observatory have done such an excellent job, I turn it over to all the Eruptions readers and their memories of the eruption. Now, as…

Time to play a little catch up … Eyjafjallajökull erupting in early May. Image by and courtesy of Martin Rietze. A brief update on our friend Eyjafjallajökull – the eruption plume from the volcano was considerably taller yesterday, reaching 6-9 km (20,000-30,000 feet), but prevailing winds meant the ash hazard was confined to areas in…

Mount St. Helens erupting in 1980. Just a reminder … please send them to me by May 15 so I can get them all ready for the post on the 18th! As many of you might (or might not) now, we’re heading towards the 30th anniversary of the dramatic eruption of Mount St. Helens in…

Mt. Saint Helens erupting in 2004. I had a chance to watch a new NOVA special that airs May 5 (PBS) on the 1980-1986 and 2004-2008 eruption cycles at Mt. Saint Helens, along with the recovery of the blast zone from the 1980 eruption. It is a fitting episode as we approach the 30th anniversary…

Mt. Saint Helens erupting in 1980. As many of you might (or might not) now, we’re heading towards the 30th anniversary of the dramatic eruption of Mt. Saint Helens in Washington state. Now, I could fill a book with the information out there on the volcano and the eruption, but instead, I think it would…

News! Colima in Mexico erupting in 2008. The current activity at Eyjafjallajökull is more-or-less unchanged, with strombolian activity producing a 3-4 km tall ash-and-steam plume and the lava flows at the crater moving northward towards the Gígjökull glacier. You can check out an extensive page on the state of this eruption at the Nordic Volcanological…

Hard to believe, but there is other volcano-related news in the world … So, with all deference to Eyjafjallajokull, here it is: Dome collapse on Colima in Mexico, image taken March 30, 2010. The new Smithsonian/USGS GVP Weekly Volcano Activity Report was issued, with news about increasing signs of activity at Egon in Indonesia, a…

Lots to do! Tourists flock to the Eyjafjallajökull-Fimmvörduháls in Iceland. The media does love the term “supervolcano”, and a number of Eruptions readers sent me a link to the article on the dreaded submarine “supervolcanoes”. I would delve into this article from Live Science, but it sadly again does a dreadful job with a lot…

Reawakening Redoubt?

The steam plume from the new dome on Redoubt, taken in January 2010. Image courtesy of USGS/AVO, taken by Dennis Anderson. 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…
