Though not as famous as Eyjafjallajökull, Katla or Laki, when Grímsvötn pops it pops.

From Iceland Monitor, September 16:

There is every indication that the Grímsvötn volcanic system under the ice cap of Vatnajökull glacier is ready to erupt, according to Benedikt Gunnar Ófeigsson, deformation scientist at the Icelandic Met Office, mbl.is reports. Grímsvötn is the most active volcanic system in Iceland in Holocene time, that is, for the past 11,700 years.

Data obtained through a GPS station on top of the glacier show that the ice cap over Grímsvötn continues to inflate. “The ice cap inflates, mainly because meltwater flows into the lakes,” Benedikt explains.

A second GPS station nearby, on a cliff in Grímsfjall mountain, southeast of Grímsvötn, has registered inflation as well. “That station shows increased inflation, which is due to magma accumulation,” Benedikt states....
