An Icelandic volcanologist was just interviewed on C4 news. He reports seismic activity near Katla saying an eruption is 'very likely'
Apparently there is a strong link between the two volcanoes going back to the year 920. From what I read Katia normally goes off every 50-60 years. Last big one was in 1918 although there might have been a smaller on in 1955. So we're about due. It's also been rumbling since 1999.
Another big volcano in Iceland let go in 1783...

It started 8th June 1783.
The summer of 1783 was the hottest on record and a rare high pressure zone over Iceland caused the winds to blow to the south-east. The poisonous cloud drifted to Bergen in Norway, then spread to Prague in the Province of Bohemia by 17 June, Berlin by 18 June, Paris by 20 June, Le Havre by 22 June, and to Great Britain by 23 June. The fog was so thick that boats stayed in port, unable to navigate, and the sun was described as "blood coloured".
In Great Britain, the records show that the additional deaths were outdoor workers, and perhaps 2-3 times above the normal rate in Bedfordshire, Lincolnshire and the east coast. It has been estimated that 23,000 British people died from the poisoning in August and September.
The haze also heated up, causing severe thunderstorms with hailstones that were reported to have killed cattle, until it dissipated in the autumn. This disruption then led to a most severe winter in 1784, in which Gilbert White at Selborne in Hampshire reported 28 days of continuous frost. The extreme winter is estimated to have caused 8,000 additional deaths in the UK. In the spring thaw, Germany and Central Europe then reported severe flood damage
