The Great American Volcano – Aniakchak

This is a repost of an article from October 28, 2013. The Caribou was standing on the plains 30 kilometers away from the mountain; it had not fled the roaring mountain more than that. After all, the ash was driven by the fierce wind to the north, and where it stood to the west in…

Pavlof having a Hekla moment

Hekla is famous for its short run-ups prior to eruption, typically the run-up involves a smattering of small earthquakes for an hour or so and then it goes boom. Pavlof has the same nasty habit of not announcing upcoming eruptions. At beast you get a few harmonic tremor episodes in the hours prior to an…

Kawah Ijen and Active Mitigation

Imagine that you are Gunung Merapi and that nobody cares about you since there is much more famous volcano named Gunung Merapi. And to make things worse it is also located in Java, Indonesia. So, you think long and hard and through a few well placed eruptions you create a side vent with a very…

Volcanoes of Saudi Arabia

The rocky desert stretches as far as the eye can see: a fascinating vista, forbidding and seemingly unending. Distant hills shimmer in the heat and glare of the Sun. There is beauty here but it is on an inhuman and unearthly scale. The land has been baked bone-dry by many years of sun, heat and…

The Art of Fracking a Volcano II

In this part of the series I will take a look at the risks of harvesting geothermal energy. Let me begin with stating that so far there has been no large accident caused by harvesting geothermal energy. On the other hand, there is no such thing as totally safe ways to harvest energy. We all…

Love Lava. Love Life.

DIANA BARNES This post was run almost a year ago (February, as will be obvious from the start) but has remained an old favourite, often talked about but now hidden in the catacombes of the lost site. VC is taking the liberty of doing a re-run of this celebration of life. It’s Valentine’s day this…

1809: The missing volcano

Large eruptions are well known. Mention Pinatubo, Mount St Helens, Krakatoa, Thera, and everyone knows something about it. The Tambora eruption of 1815 is the largest of this set: it caused the “year without summer”, left tell-tale marks in the ice sheets, and remains a terrifying example of the destructive power of volcanoes. But the…

Gunung Egon heading towards an eruption

According to local news and reports from the BPBD in Indonesia evacuation is taking place of three villages close to the volcano. So far 1 200 people have been evacuated using military trucks. Furthermore 2 000 masks have been distributed to those who are waiting to be evacuated to help protect them against the heavy sulphur fumes.…

The Endurance

Shackleton’s Lost Volcano

During his Antarctic expeditions, Shackleton left a volcanic legacy by overseeing the first exploration of Mount Erebus. But in his reports he notes an indication of another volcano, one which has never been identified. In this post I propose the first identification of this mystery volcano. Each their own. The three most famous explorers of…

Diamond!

Carbon is amazing. Where would life be without it? It forms short molecules, including the one essential to (previously) intelligent life, ethanol. It forms long linear molecules (aliphatics), round molecules (aromatics) and even spherical molecules (fullerenes) or cylinders (nanotubes). As a solid it forms thin, strong sheets (graphite). If such a sheet is composed of…
