Coulées!

As a volcanologist, I am partial to impressive lava flows, especially in volcanoes that erupt material that you’d think wouldn’t produce big flows. For example, there are quite a few volcanoes in the Chilean Andes that erupt dacite lavas, which are relatively viscous (sticky), so you might expect it to erupt explosively. However, you can…

Icelandic eruption from space

Alright, I’m actually in Wisconsin right now for a wedding, but this was too cool to pass up … the folks from the NASA Earth Observatory sent me this image (Natural-color, 10m/pixel) from the Advanced Land Imager aboard EO-1 of the Eyjafjallajokull-Fimmvörduháls eruption, both taken on March 24, 2010. The Fimmvörduháls eruption in Iceland, taken…

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,…

Cleaning up some news … busy week leading up to a field trip I am helping co-lead to Death Valley next week. Ubehebe Crater in Death Valley, California First off, I want to say how amazed I am at the great discussion that went on all weekend about the signs of potential activity in Iceland.…

Holiday snaps from space: Sakurajima

Eruptions reader Tim Stone sent me a link to the TwitPic feed for Soichi Noguchi, the Japanese astronaut currently on board of the International Space Station. The space traveller got a shot of Sakurajima from space, showing a beautiful…

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…

A couple bits of news: The ash plume from the February 11, 2010 eruption of Soufriere Hills taken by theAqua MODIS camera. Image courtesy of the NASA Earth Observatory. Flights have been disrupted in the West Indies since last week with the large dome-collapse eruptions of Soufriere Hills on Montserrat. The 10 km / ~35,000…

Two impressive eruptions going on right now: Soufriere Hills erupting on February 11, 2010. Image courtesy of the Montserrat Volcano Observatory. Soufriere Hills just keeps on raising the bar during its new eruptive period. The volcano on Montserrat in the West Indies produced a 15 km / ~45 000 foot ash plume as the summit…

News! Pakistan is home to the world’s tallest mud volcano in the region of Balochistan – and its somewhat near the reports of an “eruption” earlier this week. Guess what? Since Wednesday evening, seismicity at Yellowstone has dropped precipitously. The last batch of earthquakes on February 3rd were also back to deeper levels – 8-9…
