News for Monday! Ngauruhoe in New Zealand, showing the dark lava flows of basaltic andesite on the slopes of the young volcanic cone. Image by Erik Klemetti, taken January 2009. A couple pieces of news from two Russian volcanoes on the Kamchatka Peninsula: (1) last week’s report of activity at Gorely appears to be semi-substantiated…

Tungurahua in Ecuador erupting on May 31, 2010. Two volcanoes along the edge of the north Pacific had explosive eruptions over the weekend. We have some more details on both of the eruptions, so I’ll pass them on: Bezymianny KVERT is excited because they claim to have predicted the explosive eruption of Bezymianny almost to…

Brief news! Lava flows reaching the sea at Kilauea in Hawai`i. Image from November 2009, courtesy of HVO/USGS. The Alert Status at Cleveland in the Alaskan Aleutian Islands was raised to Yellow (Advisory) by the Alaska Volcano Observatory after new signs of activity emerged. The latest report from AVO on the volcano says a thermal…

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…

I’m still playing catch-up after my week in the desert, so I’ve seen a lot of articles I’ve wanted to mention … but a certain other volcano has taken up a lot of my time. However, I will attempt to make amends for that now. By the way, would you believe Ubehebe Crater was closed?…

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,…

Catching up with some news: Anatahan erupting in the northern Mariana Islands in 2003. I ran across this article right before I got sick, but its been popping up around the interwebs (and is pretty interesting). It details a study in Molecular Ecology that suggests that populations of caribou in Canada’s Yukon Territory were strongly…

Not a lot of big news, but a lot of little news: Soufriere Hills at night during the late January 2010 dome growth episode. Note the hot rock falls from the collapsing dome. Image courtesy of Photovolcanica. This might not be new, but Dr. Boris Behncke brought the new webcam at the rim of Chaiten…
