New media hype over Katla volcano

There apparently is a new media hype over Katla volcano in the British press. This time around it is from BBC News. The news in question claims that a eruption in Katla volcano is going to have a global impact. This is nothing but a exaggeration in my view. While a eruption in Katla volcano might be big, there effects are mostly localized to Iceland. This was clear during the Grímsfjall volcano eruption in May of 2011. Where the global effect was close to zero, there where some flight disruptions. But they where not something major like did happen during Eyjafjalljökull volcano eruption. So the media is overestimating the effects of eruption in Katla volcano. To what end I do not know. But it sure annoyed me, and the scientists that monitor volcanoes in Iceland.

It is also important fact that Katla volcano did have an eruption this year. It took place on 8 and 9th July, 2011. With a smaller eruption on the 10th of July, 2011. This eruption was however a small one and did only melt the glacier, as it was not strong enough to break trough the ice. My coverage of those events can be found here (the whole timeline of events can be viewed here).

In terms of effects of a large eruption in Katla volcano. One thing is clear. It is mostly going to local to Iceland, it might disrupt flights in Europe of the wind systems are unfavorable. Both over mainland Europe or for transatlantic flights. But transatlantic flight can in most case route around the ash clod if it they need to. But the claim for global effects are just exaggeration and nothing else.

The BBC News hype.
