ESA Satellites are showing clouds of sulfur dioxide exiting from Iceland’s Bardarbunga volcano.

It may be mostly hidden underneath the Vatnajokull glacier in the center of the country but Bardarbunga isn't shy about saying hello, it has had up to 400 eruptions in the last 10,000 years, one of which produced more lava than any other volcano on Earth during that time.

23 of those were geologically recent.

Bardarbunga eruptions seem to happen even more often than colony collapse disorders in bees, so Iceland knows it's best not to get too complacent when something sitting on two volcanic rift zones starts to put on a show:  It seems to erupt twice per century on average and the last one was in...1910.

Tick tock, tick tock...
