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…

The NASA Earth Observatory has been dazzling us with images from the Eyjafjallajökull eruption for months – but they have been dazzling us with volcanoes images for years! Here are two more images for those of you who love seeing volcanoes from above: Cleveland, Alaska As I mentioned earlier this week, Cleveland volcano likely had…

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…

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”.

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…
