A little off topic, but if it goes off and is in the news, it will be useful to know how to pronouce Bárðarbunga: http://www.mbl.is/frettir/innlent/2014/08/19/how_to_pronounc...

The key is that 'ð' is not really a 'd' sound, it's a 'th' sound. But it's the 'th' sound you make in 'feather' and not like the one you make in 'this'. (Pay attention where your tongue is as you say the words; all "th" sounds are not alike. The other 'th' sound is 'Þ' in Icelandic)
