Water, Grimsvötn and Stromboli

After a couple of rather hectic volcanic weeks in the world of volcanoes I thought I would write a little something about two of these events. Namely Stromboli and Grimsvötn, the reason I am cherry picking those two is that they have a common theme, water.   Stromboli Unless you have been to Stromboli you…

Cafébar and Thou shalt not Waffle

I grew up in a news publishing family. This means that for me freedom of speech and, the right to freely discuss topics is a given. But, at the same time as it is a given and necessary right, it comes with responsibilities. In the end the rights and responsibilities go hand in hand with…

The mystery of The Mysterious Island

If there ever was a patron saint of Volcanocafé it would be the author Jules Verne. When he was not inventing cadres of literary genres, he was quite obsessed with volcanoes. When he was not writing he spent his time reading about volcanoes (and other things scientific). And quite often he combined his interests of…

Getting to Greíps with things

In this article I will pick up with the questions regarding age, GPS-tracks and the general setting. Knowing me it is quite likely that I will meander out into wild tangents as I go. Time to Greíp my pen.   The age of Greíp For a volcano that has not erupted (we will get back…

Unrest at Torfajökull

  This is just a short piece about mounting unrest along the extension of the Veidivötn Fissure Swarm as it is running through the Torfajökull volcano. Torfajökull has two known magma reservoirs, one on the south east side that is mainly andesite-basalt, and a rhyolite chamber towards the south-west. The current lineament is having the…

Greip: A prequel on instrumentation

This is both an informal start of our series about a promising central proto-volcano, and a story about the problems of sifting through the bewildering number of signals that the instruments yield for us to peruse. Let me start out in the stars. A friend of mine work with SETI, the search for extra-terrestrial signals.…

The Life Aguatic

We got a letter from one of our readers this week pointing out a seismic series near Agua volcano and Ciudad de Antigua in Guatemala. “I’ve been living in Guatemala for a while, staying in Antigua. On April 27, the area around, and on, Agua volcano started to shake. We felt at least 8 quakes…

On the importance of Deep Quacks

Back in early 2011 I was sitting down for a late light evening read of “Lower-crustal earthquakes caused by magma movement beneath Askja volcano on the north Icelandic rift” by Soosalu et al. As I read angels started to sing a glorious hymn as I had an epiphany and my view on how volcanoes operate…

The most erect of volcanoes?

Have you ever wondered about which is the tallest active volcano on the planet? It sounds like a fairly straightforward question. But, as with all simple questions it quickly turns into a quagmire of definitions. The first of the definitions starts out in linguistics, and that is what is the definition of “active”. It turns…

Michio Kaku and the stale dough

Flat earthers believe that the earth is flat, but the rest of us have good reasons to think that we know that it is round. The difference is that they trust in their belief in something, and that we trust the scientific process and the data and theories that it yields. A flat earther stubbornly…
