Hi, this is my first post here, I've been lurking and attempting to soak up info as I go along, since I have no idea when it comes to winter weather.
I have however been keeping an eye on Fagradalsfjall. This is an effusive (non-explosive) eruption, meaning the lava gets a long time to cool and doesn't form ash, so there's very little chance of that disrupting anything. Sulphur Dioxide emissions may be worth a look as that does cause atmospheric cooling, and this eruption is a big one, bigger than the previous eruption this year, the fissure already looks to be 4km in length.
I was joking in November when the tremors started that we'd get a white Christmas if it erupted, especially seeing as summer was very mild while the other volcano was active (probably coincidental). I wasn't really expecting to be hit with the gift of prophesy
