News reports in Iceland of magma movements in Hekla.

Nope, not Katla, this is the prototype Northern European volcano – Hekla

No, that doesn’t mean we have given up on Katla, or Hengill, or Askja, or Krýsucík, or any of the other hot spots on the mid-Atlantic ridge that have been rumbling recently.

There is still a steady stream of small earthquakes in a line going 1-10 km under the central caldera at Katla, and the area on Reykjanesskagi near Krýsuvík is both swelling and shaking.
But, Hekla erupts often, and usually with little or no warning. There was one small earthquake there, but GPS measurements have been showing steady lift, and now there are signs of low frequency harmonic tremors which can be signs of magma moving near the surface.

Hekla has many minor “tourist” eruptions, and then the occasional rather unpleasant major eruptions… like the 12th, and 14th and 16th and 17th and 19th and 20th centuries… but the last 4 eruptions were minor, and the good news is that the less time since the last eruption, the smaller the eruption is likely to be.
Usually.

    What the hell do you Icelanders and your angry Volcano Gods want from us? Money? Virgins to placate Jörmungandr the World Serpent? I need to cross the North Atlantic in a couple months, so if you all could just come out with a list of demands, we can get this over with.

    Hmm, I’m crossing the Atlantic later today. Hopefully I’ll be able to get back…

    Well, there’s a lot of activity all over.
    Just now a spot off-shore lit up with a bunch of little earthquakes.
    If that keeps going, then we may be looking at an underwater eruption on Reykjaneshryggur, possibly leading to another Eldey – a new island appearing.
    Or not.
    Any of these can go quiet again for a long time.
