Askja, 1875

Background Askja is a lesser known major Icelandic volcano. The north volcanic zone (NVZ) where it is located is not as touristy as the east (Bardarbunga, Grimsvotn), the south (Katla) or the southwest (Fagradalsfjall) volcanic zones of Iceland, but it should not be ignored. The Krafla rift eruption here lasted (intermittently) for nine years, from…

The changing faces of Fagradalsfjall: fizz, bubbles and slugs

We have had quite a ride. The eruption began unseen, on March 19. The new fissure opened on April 5, after the initial double cone had begun to wane. The new fissures sprouted a series of cones, mostly twinned. By May, all twins had exterminated one of the siblings, and the survivors had battled for…

The Sicilian Affair

This of course was our April 1 story, bringing volcanoes up-to-date with the modern world of ‘alternative facts’. We hope you enjoyed it and that it brought a smile to your face. Any resemblance to any person anywhere in the world is purely intentional. Tune in next year when we will be revealing the volcano…

Fukushima in two volcanoes

Today is the 10 year anniversary of the Tohoku earthquake. The M9 off the coast at Sendai, Japan, was impressive enough by itself, but the main impact came from the huge tsunami that followed. I remember it well. My lecture the previous day had been on the physics of tidal waves and tsunamis. I had…

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

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…

VolcanoCafe delicacies

We live in a time of volcano famine. Eruptions are hard to come by, and many scheduled events have been postponed until after covid. And the travel restrictions pose insurmountable problems for volcano watchers. By the time we have flown to the imminent eruption, spend two weeks in quarantine in the VC dungeons isolation ward…

The Urban Volcano

Guest post from Tallis If you were to ask a volcano enthusiast “What is the most dangerous volcano on the planet?” you’d get a range of answers. From a novice, Yellowstone, from someone who only knows of American calderas, the Long Valley caldera. The generic but not wrong, Vesuvius, Mt Rainier, Campi flegrei, Paektu, Santorini,…

Bagana: child volcano

It is hard being a child of a famous parent. It means living under a cloud of expectation. Society expects children to be like the parents. Parents expect children to become a better version of themselves. Parental pressure can be particularly strong on the oldest child. Younger children may have more freedom to do what…
