Keilir

When a year ago Thorbjorn was inflating and seemed at risk of erupting, we put out a post to describe the volcanics of the Reykjanes peninsula. The front picture of the post was of a small cone no one had ever heard of. And now, a year later, that cone is at the centre of…

Possible runup phase at Fagradalsfjall

Today it became reinvigorated with 10 earthquakes above M4. At the same time the earthquake swarm go reinvigorated signals was detected pointing towards movement of volcanic fluids…

Iceland’s eruptions since 1900

In 1900, Iceland was a very different country. It wasn’t a country, for one thing. Although Iceland had been granted self-rule, it was still a part of Denmark and the local leaders were largely Danish-educated. There was still a Danish governor. The position (not the governor) was terminated in 1904. On Dec 1, 1918 the…

The Heimaey story

Heimaey is famous. It is the only place in Iceland known to have first been settled by non-Vikings: the first inhabitants were escaped Irish slaves, before 900 AD, who didn’t last long. Much later it suffered a devastating slave raid. And of course, it has an elephant. But all that history pales in comparison to…

The Hotness of Grimsvötn

As far as volcanoes go, we like to think of them as immutable giants that rarely if ever change. We like to see Grimsvötn as a glacier covered giant of a volcano, that almost always produce moderate ashy eruptions, that are relatively speaking short-lived. Yes, once upon a blue moon it will do something big,…

Volcano ecology

Space is a precious resource. We hoard it and guard it. Together with air, water, warmth and tomato ketchup, it is one of the essential ingredients for life. We are happy to share empathy, food, and money, but letting someone else invade our personal space is a big step well beyond that. Social distancing is…

Laki: the making of a fire

Laki was one of the defining events of Iceland’s history. Its impact went well beyond the nation, covering much of the northern hemisphere. It seems amazing that something that caused so much suffering was seen by so few people. This it shares with Eldgja, which was even larger and must have devastated Iceland, but of…
