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

The current swarm at Reykjanes Peninsula that has been going on since the M5.7 NW of Krysuvík on Wednesday at 10.05 declined over the last couple of days. 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…

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 deconstructed: I. prequel

Central volcanoes of Vatnajökull With all volcanic activity seemingly on hold during the shut-down, here is a re-post from the dungeons, originally published May 29, 2013, and written by Carl. It leads into a post on Laki which we hope to put on in the next few days. After that, who knows. Perhaps something on…

Þorbjörn’s Tormented Tribulations

As Þorbjörn rumbles on it seems ever likelier that it will erupt. So, to explain what is happening I decided to pull out all the stops and produce a more definitive article explaining the news and a possible future now that Albert has put things into context. So, without further ado, I would like to…

A Reykjanes story

Iceland does it rather well. Over the 1100 years or so since the Viking settlement, it has erupted some 63 km3 of lava, the large majority of it basaltic. A similar volume of tephra was also produced. The East Volcanic Zone is the prime suspect for any eruption, and with good reason: it is responsible…

The Woolly Mammoth-Sized Eruption Poll – One Year On

It’s been one year, yes one whole year of DNA damage and telomere shortening, since the last poll and we’re all still waiting to see who’s going to go first. We’ve seen activity increase in some areas and decline in others. Will that have swayed your opinion or will you stick to your previous vote…
