If you've been to Iceland you've probably been near volcanoes, just not necessarily active ones. This volcano that is currently erupting is only about 10 miles from Keflavik Airport (and maybe 5 miles from the Blue Lagoon, if you went there).

Haha you would be right then. Only saw some geothermal vents and hot springs but yeah, there is a lot of earth activity going on there.

Definitely exercise caution when parading around Iceland: nobody is going to stop you from walking yourself into something hot/dangerous.
