It now looks as though this eruption is quietening down considerably.
In the first 24 hours it spewed out more ash than the eruption last year did in 40 days.
This is the biggest eruption for more than 50 years.
The Grímsvötn Eruption let Out More Ash in One Day than Eyjafjallajökull
Note that this is not the volcano that they were saying could erupt because of the one last year.
