The Grimsvötn eruption of 5 May 2021

38 per cent of all eruptions in Iceland come from Grimsvötn. It is an amazing number: this hidden volcano, invisible and unreachable to all but the most hardy explorer, is among the most active volcanoes in the world. Not the most active: the volcano with the highest frequency of eruptions is Mayon, which has erupted…

Volcanic alert at Þorbjörn Volcano

The Icelandic Met Office has released an Official Bulletin about the possibility for an upcoming eruption at Þorbjörn on the Reykjanes Peninsula in Iceland. Þorbjörn belongs to a class of volcanoes that I normally like to call Unknownabunga, one of all of those volcanic features in Iceland that pretty much nobody knows anything about, until…

Taal eruption update

In my previous article I wrote that Taal most likely would not continue to erupt for a long period of time, based on the previous history of the volcano. Obviously Taal decided to go for something not recorded in the historic annals. It is therefore time to take a deeper look at what is going…

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…

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…

Greip Expectations

  Part 1 of a Greip Series This week, under the rumblings of Torfajökull, we return to one of our favourite areas within Vatnajökull that is yet to show it’s true hand. Or has it already and is there evidence to support that? Due to some recent activity, Carl has been getting increasingly excited in…

A volcano year

This is the time of the year when people like to look back. What was the year like? Good or bad – or, as is almost always the case, a bit of a mix? And if looking back is not your thing, newspapers run columns where specialists (of varying level of expertise) are given a…

Living dangerously: another Grimsvotn prediction

  Grimsvötn is heading for an eruption. There can be no doubt about that. Of course, it is always heading for an eruption. This volcano has ADHD. For Grimsvötn, more than a decade of brooding is unusual: normally it just throws it out. A misplaced snow flake can set it off. And it produces not…

Signs and portents of Iceland – Revisited

When I planned to write this article about the current states of Iceland I only wanted to write about Katla and Öraefajökull. But, as things turned out a third volcano got my attention. In the end this article will be about how hard it can be for a layman to see what is important and…

Ancient foundations: the earth of the bible. Part I: Tectonics

Humanity has a long history of living on this Earth. During the days and years, our world continuously changed. We grew up in the shadows of the approaching ice ages. We left Africa when the changing sea opened up a road to Asia, and followed an ever-changing coast line to the far East. And throughout…
