A few days ago, in the VC back-channel, I made mention of something I had seen on a SciChan program. That October is the anniversary of the 79AD eruption. Albert then chimed in with a link to a BBC article detailing the same. https://www.bbc.co.uk/news/world-europe-45874858 Okay, that’s the second thing about October that is interesting. 25…
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.…
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,…
I love large caldera volcanoes. The first reason is that they are always very beautiful, especially if they have lakes in them. The second reason is that most of them are of a class of volcanoes that leave their pointier cousins far behind. Size matters after all. At one end of the beauty spectrum, you…
Geological time is interesting, because even the geological now is decades long, if not centuries. The current geological episode at Reykjanes didn’t start with Fagrafjall (it is no longer a valley, so let us drop the “dal” out of Fagradalsfjall shall we). Nor did it start with the large and very noisy intrusion over at…
In the last few weeks, I have been unusually busy with things decidedly non-volcanic as the world turned quite a bit darker. Regardless I noticed that there were quite a few things going on in the volcanic part of the news, but that did not for natural reasons end up as big news items. One…
As the numbers for the Hunga Tonga eruption continues to come in it is becoming ever clearer that something truly momentous happened, something not seen or heard in 139 years. With a columnar height of 55 kilometres, an explosive pressure wave travelling several laps around the planet, forming a medium sized deadly tsunami, gouging out…
As more information comes in, it is time for a brief update, and for a theory on why the eruption of Hunga Tonga was so destructive for what was, after all, a fairly small volcano. The death toll of the tsunami at the moment stands at five, three at Tonga and two in Peru. There…
It seemed to come out of nowhere. In the midst of a quiet interlude, after the hugely damaging La Palma had ended, when the hugely touristic eruption at Fagradalsfjall failed to re-appear, and the hugely underwatched eruption at Kilauea continued to be underwatched, whilst we were waiting for Reykjanes (which some had predicted to recur…
First of all, I should clearly state that there are no current signs that an eruption at Katla is about to happen in the near future. Instead, the reason is that I was asked by one of our readers, Patricio Oliver, what would happen if the volcano erupted, especially for the inhabited areas. This is…
