The Fagradalfjall eruption series II – day 2

The end of the Australian TV series Neighbours (which I to my embarrassment never watched) has created room for new home entertainment series. Iceland has stepped into the breech, and has created a serial volcanic eruption. We are now on series II of the Fagradalsfjall fires, just in time for the empty summer holiday schedule.…

Fagradalsfjall eruption 2

After several days of heavy shaking, the new eruption started today. We know very little and are mainly enjoying the view. That there was an eruption is not a surprise, the location perhaps was. The earthquakes showed an intrusion in the general area of Fagradalsfjall. They were located a little east of last year’s dike,…

Nyiragongo and its ultra alkaline magma – Part III

Introduction  In part one I took a close look at the large scale forces that drive volcanism in Africa, at continental rifting in its different stages and the types of magma chemistry that form because of it. I also discussed the origin of the forces that created Nyiragongo and Virunga in the first place. In…

The volcanic edifice itself measures around 13 kilometers wide and rises to 3470 meters above lake…

It’s also a very problematic volcano, close to a huge population center that is rapidly growing, and there is a lot of risks associated with its volcanism as well as with…

Appropriately, the origin of this expression – slightly rephrased from the original Star Trek series – is from the second-most-famous non-human in existence, Spock, referring to a living rock. It is only a small step for humankind to…
