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.…

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…

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…

Hekla – Small things and stars in the night

I was asked to write a small weekend piece while we wait for Albert to finish the second part about Grimsvötn. My original idea was to write about people eating volcanoes, but thankfully Iceland saved us from that. As many of you have noticed Grimsvötn has thrown some big ones since my part of the…

Living Dangerously – Grimsvötn Forecasted

In August of 2017 Albert and I stuck our necks out on a limb and made a forecast each of what the future pattern of Grimsvötn was most likely to be. Or in other words, when would it erupt next. As I reread our two separate forecasts, I am struck by how different methodologies we…

Activity at Hekla and The Dead Zone

While we are waiting for Öraefajökull to drop a Christmas present and Grimsvötn to hatch an Easter egg, we instead might get a gift from Hekla. And at the horizon suddenly, a far darker bird looms. So, once more we must ask and answer the age-old volcanic question; what gives in Iceland? Hekla Many people…

Iceland in ashes

I had never seen the Manchester sky so blue. The usual milky white which goes by the name ‘Manchester sunny day’ was gone, transformed into an azure experienced mainly during distant holidays. Great Britain of course has a bit of a reputation. Already the Romans wrote that “the atmosphere in this region is always gloomy”.…

And The Woolly-Winner Is…

Thank you to all that voted, we had a great turn out which certainly helps distinguish clear winners and other voting trends. I hope some of you managed to find the time to read up on some of the volcanic features you’d never heard about and gained some insight along the way. So, without further…

The Woolly Mammoth-Sized Eruption Poll

Following on from Carl’s latest post on some unrest in Iceland, I wanted to gauge public opinion on who they thought was going to make the headlines proper rather than the usual clickbait nonsense from the bile-spouting tabloids. I hope recent misleading headlines haven’t swayed our visitors into voting for their latest scare stories! Try…

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…
