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…
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”.…
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…
Time and again we see the statistical fallacy pop up in regards of volcanoes, and then as a letter in the mail, the word “Overdue” is dropped in our mental mailboxes. But, fear not, there is a hero of sanity out there in the form of the greatest philosopher of all time to save us…
In the first part of this post, we looked at magical carbon and where to find it. We now continue to look at how much CO2 volcanoes produce, and how it compares to our own emissions. Who wins the battle? The results of the polls are: A small majority believes that volcanoes produce less CO2…
The world we live in has a volcanic history. The continents ultimately came from volcanoes, often volcanic arcs, in some cases several billions of years ago, in other cases more recently. All ocean floor is volcanic, made in mid-oceanic rifts within the past few hundred million years. And the volcanic contributions do not stop there.…
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…
Carl – May 9, 2014 (re-post) In the west corner of the ring you find Yellowstone wearing blue, red and white striped trunks and in the east corner you find Grimsvötn wearing Fire & Ice colored trunks. Welcome to a spectacular fight about who is the largest, meanest volcano on the block. As the fighters are…
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…
