I said there'd be more.
Grimsvotn's eruption produced an intense lightning storm. It doesn't look as impressive as Eyjafjallajokull's lightning but Grimsvotn produced 1,000 times more lightning strikes per hour.
The initial plume of ash from Grimsvotn was also higher than Eyjafjallajokull, 20 kilometres as against 8 kilometres but has now dropped to about 15 kilometres. The ash content of the cloud is much coarser and less likely to remain airbourne and be blown as far as the lighter ash of Eyjafjallajokull.
That's not to say it hasn't affected Iceland already. People have been told to stay inside, farmers are also rounding up their animals and flights have been stopped.
