The Sperm and The Volcano

I will this time temporarily deviate from the usual style and subject of Volcanocafé. The reason I am doing that is due to the grave importance about which I am writing. But rest assured that there will be a sideshow of volcanism, and even some geology. For those who do not wish to have their…

Volcano Cafe 2.0: Welcome to the Mars Bar

We hope you enjoyed this April Fool’s post! It was designed to sound believable, up to the point you got to either the beer or to the news in the Mars Times. (‘Tiu’ is an old english word for ‘Mars’, as in ‘Tuesday’.) But rest assured, nothing in here is true, especially the bit about…

The Bogoslof update

A year ago there were frequent eruptions of Bogoslof volcano. But over the months, it dropped out of the news, as the eruption quieted down and finally ceased. This brief post is a recoup of what came before, and what the state of the island is now. Bogoslof is one (and sometimes two or three)…

Black Swans and Iceland

Two weeks ago I wrote about statistics and the possibility to predict volcanoes in any way by using statistics. I think that the point was a bit lost, my entire point was to show that it was impossible to in any useful manner predict when an eruption would occur, and also that it is impossible…

When Pinatubo turned the tide

The sea is our fascination. We go out of our ways to find it, and it is where we go for holidays, spending our time lying on the beach. Close to half the world’s population lives within 100 kilometers of the coast. For those who live here, there is a good living to be had,…

The Mayas and their lack of volcanoes

Alberts latest article was a tour de force of the classic view of Mayan collapses, as it has been perpetuated in classic literature. The general idea is that the large downfalls in the Mayan empires would have been caused by large distant eruptions. This is of course an unfair summing up of Alberts quite more…

Sheet dyking at Skjalfandi

We rarely, if ever write articles about earthquake swarms at the Tjörnes Fracture Zone. The reason for that is glaringly obvious, those swarms are incredibly common. Pretty much, a day without fairly intense activity is a rare beast indeed. So, this is a bit outside of the ordinary programming. The area is one of the…

The Kazbek disaster: a cryoclastic debris flow

What makes a volcano dangerous? Clearly, the severity of any eruption plays a role. So does the presence of people nearby. But it is not always the best known volcanoes that are the most dangerous. Tseax is hardly world-renowned, but it caused a major volcanic disaster in Canada. And sometimes a volcano can be dangerous…
