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.

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

A few weeks ago, I was asked by a person who did not believe in science this specific question. “If plate tectonics are real, why then are there no volcanoes in Norway?” It is a…

A volcano is born unto us

A bit about the importance of data-plots It is now many years since I did any heavy scientific lifting. But, the fun part of writing for Volcanocafé is that I get to do quite a bit of work in the field of volcanology in a relaxed popular science setting. It is a rather well-known secret…

Volcano at fault: Neenach and the art of moving mountains

The San Andreas fault makes a great bend around the city. It leaves its citizens well separated from the real America. On the rim of the Pacific, Los Angeles has become the ultimate laid-back city.

Gunung Agung and the potential future

Most people have by now noticed that Gunung Agung has stopped erupting. And to understand why that has happened, and what will happen soon, we need to look at what happened during the eruption.
