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…
“The sun became dark and its darkness lasted for one and a half years… Each day it shone for about four hours and still this light was only a feeble shadow… the fruits did not ripen and the wine tasted like sour grapes.” Michael the Syrian, about a 6th century eruption It smells. Sulfur is…
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…
I got the honour and privilege to be the author of the first blog post of 2018. So let me take this opportunity to wish all our readers, visitors and the managing team a very happy and healthy new year. The Bardarbunga eruption in 2014 was impressive in many ways. It was a rifting event,…
Ever since I began plotting earthquake data for Iceland and generally for the world (where data is available), I was planning to do a monthly review of the seismicity in Iceland, so we can keep track of it on a monthly basis. Of course, if there is any stronger activity or something unusual happens, usually…
In this article, we move away from the usual suspects in Icelandic volcanism and turn our attention to a feature many of us have noticed over the years. This feature has only been revealed from seismicity, but here I try to unravel the past and future activity as well as give this feature a sense…
In physics, there is a famous tenement that reads as, ‘cause and effect’. But, for Hekla I find that the founding principle of the Bauhaus school of modernist architecture is far better suited to express what I will be trying to model and express here. It states that the form of a building will at…
A little while ago there was a short interview published with Professor in geophysics, Páll Einarsson. In the interview it seemed like he was stating that Bárdarbunga, Grimsvötn, Hekla and Katla all were preparing to erupt shortly. First of all let me state that I deeply respect Páll as a geophysicist, problem is just that…
Being considered the world leading authority on something is probably more of a curse than a blessing. All of a sudden you have a reputation to defend and everyone will be annoyed with you when you do not agree with their interpretation about what is happening. To top it off there will be a not…
Icelandic volcanoes are all about long term projections. They do not do things in the short run, before any eruptions you will see either several intrusive episodes like at Eyjafjallajökull, or you will see signs of steadily mounting pressure prior to an eruption. For some Icelandic volcanoes these two processes goes on for decades, or…
