Is it going to blow? If it does will the effects on air travel be as bad as 2010?

Cowabunga!
In answer to your question, due to the number of variables, nobody has a clue. Anyone who says they do is fibbing!
No one can tell what sort of eruption is likely to take place, how long it will last, how much ash and other debris is thrown up into the atmosphere, or how high it will go, or what direction it will go, because no-one really knows what direction the winds are likely to be blowing at the various altitudes the smoke and ash might get to.
Does that help?
(I am not a doctor!)

Of course its going to bugger up air travel.

I’m flying home and visiting three European airports in three weeks time, after 4 weeks away working… 🙄

I’m flying down to Geneva on saturday, it can erupt all it likes once I’m down there 😆
