Title: Icelandic Volcanic activity
Post by: Nickel2 on August 19, 2014, 11:02:20 AM
It appears that volcanoes under the Vatnajokull area have become more active recently. There is the possibility of a repeat of the air-traffic chaos of the last eruption.

When the last one went up a few years ago we had couriers bringing engine wipes from Shetland on the ferry for emergency analysis before the engineers would let them fly back to Aberdeen. Most of what we found was salt! Unfortunately I couldn't convince them to taste the deposits rather than call me out in the middle of the night.

Let's hope they ground air traffic for a few weeks - we had nice clear skies last time it happened - first time I ever remember seeing the sky without contrails.

Seems that's not so likely:

Current indications are that if an eruption happens it will produce modest amounts of denser ash and only cause local disruption to air travel.  But we know so little about this volcano that she could surprise us.

Katla is going to be the biggie when that goes up. When we were there a couple of years ago we were told that it is the one that Icelanders worry about as it is overdue for going off and has the potential to be the biggest eruption yet.

Living where I do under final approach to Heathrow I'd very much welcome a suspension of all flights for several weeks, might get a decent night's sleep!

I have no doubt that once it becomes newsworthy, Iceland will become infested with reporters.

It appears that there will be less of a risk to aviation, now that the volcanic activity has spread out to become a fissure eruption. All fascinating stuff!

Watching this all with interest.
Some great graphics of the recent activity here http://baering.github.io/

Thought this was worth a bump as the fissure is spewing lava an estimated 200m in the sky. This is it viewed from 20km
