Climate, volcanism and the Andes

The northern Chilean and southern Peruvian Andes are full of volcanoes that look stunning – I mean, jaw-dropping details of volcanism litter the landscape. The reason for this is two fold: (1) there is an awful lot of volcanism in the northern Chilean/southern Peruvian Andes (as known as the Central Volcanic Zone) – and has…

A night shot of the Eyjafjallajökull eruption showing the glowing plume from the strombolian explosions and the Aurora Borealis overhead. A quick update on the current activity at Eyjafjallajökull eruption: the eruption continues at the summit craters, but there seems to be less ash being erupted, at least yesterday. The latest update from the Icelandic…

Webcam shot of Eyjafjallajökull erupting on April 17, 2010. I don’t want to get too far into this but there has been a lot of chatter about the link between melting ice caps and increase/decrease/neither of volcanism. The two main articles we’re talking about are: Scientific American, saying that ice loss could increase volcanism: Ice…

We’ve been discussing calderas recently on Eruptions (I wonder why) and the Laacher See in Germany came up. I’ve actually been to the Laacher See on a field trip lead by one of the world’s experts on the caldera, Dr. Gerhard Worner. So, I thought I’d post some pictures and talk a little about this…

Back to work after Thanksgiving Break … lets clean up a few news items I missed trying to figure out the non-eruption of Karkar. Undated photo of the summit area of Gaua, Vanuatu. There was an actual eruption – or, more correctly, a continued eruption – of Gaua in Vanuatu. The current activity has prompted…

There have been a number of articles floating around the popular press for the last week that I thought I would touch on briefly … always fun to decipher the real news from the hype. Active fumaroles on Datun Mountain in Taipei. An article out of the Taipei Times suggests that the city of Taipei…

Lets get right to it! “Manmade volcanoes”: can they solve global warming? It does indeed seem that something is happening beneath Kanlaon in the Philippines. PHIVOLCS reports that the volcano experienced 257 volcanic earthquakes from August 23 to September 1, well above the usually “background” level of ~20-30 a week. Most of this seismicity is…

Two papers submitted, one to go. Keeps you quite busy, let me tell you. Lava flow from a 2006 eruption on Mayon in the Philippines. A few bits of news today: A few more details about the ongoing watch of Mayon in the Philippines . There have been apparently no changes in the shape of…

Tambora, Indonesia There are big eruptions, then there are big eruptions. On April 10, 1815, Tambora, a volcano in Indonesia, produced one of the largest eruptions in human history. This eruption produced what became known as the “year without a summer” after the volcanic aerosols from the eruption produced some of the coldest summers in…

AVO has kept the warning level at Red/Warning after briefly dropping it to Orange/Watch on Friday night. The 15,000 foot / 5 km-tall…
