    Any chance of Fagradalsfjall becoming another Laki?

    Could we tell if this was in for the long haul?

    It’s about a volcano near Reykjavik, Iceland. They had earthquakes for weeks, then a nearby volcano erupted for the first time in around 800 years, this happening less than a day ago (middle of last night in my time zone). It has a name I could never remember to spell without a lot of practice. As for the question about Laki, I have no idea.

    I believe it is about this Laki.

    The question is: Will the Fagradalsfjall fissure volcano on the Reykjanes peninsula erupt for as long as, and be as damaging as, the Laki fissure volcano in the East Volcanic Zone (which was an environmental disaster for Iceland)? I think Van Rijn probably meant he had no idea of the answer to that question, rather than having no idea of what Laki was.
    I guess it would depend on the size of the magma chamber feeding each--despite the very detailed surveys the Icelanders have carried out over the years, that information doesn't seem to be as easy to find as I thought it would be. The volcanic territory of Reykjanes is a lot smaller than the East Volcanic Zone, though, if that's any guide.

    The Icelanders are used to Earthquakes but the frequency and violence has exceeded experience, and the crust there is only about one kilometer thick, I read. It is more like a magma lake than a cone volcano, but despite the extensive instrumentation, the next stage remains mysterious. It could be big or small for Iceland and the surroundings.

    And now it may be over, or not!

    Yes, that was my intention. I don’t know enough geology in general, let alone the specific geology involved to discuss the question itself. But I was rushing a little and could have used a few more words to explain that.

    I read somewhere https://www.icelandreview.com/news ? that the magma chamber associated with Fagradalsfjall is small. So no major eruption spewing HFl. Of course, these early on reports tend to be a little dubious.

    True, but you have to wonder how a small magma chamber got there! Is its source now an open pipe ? Two tectonic plates moving apart under Iceland, they say. But that’s why Iceland is there. Just getting bigger.
