Eruptions

Tag archives for satellite image

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…

Idunn Mons on Venus with recent emissivity data from the Venus Express overlaid on the topography, suggesting recent lava flows. NASA released images today that suggest that the surface of Venus has experienced some relatively recent volcanic events (geologically speaking). By examining the surface in infrared, the Venus Express, launched by the European Space Agency…

Volcanoes from space!

Actually, no the volcanoes aren’t from space, but pictures of the volcanoes were taken from space. The NASA Earth Observatory has posted three more gems of volcanic activity taken by one of the fleet of earth imagers in orbit: A recent image of Chaiten taken by EO-1. Image courtesy of the NASA Earth Observatory. There…

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.…

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…
