Thordarhyrna

Thordarhyrna is one of seven subglacial volcanoes beneath the Vatnajokull glacier in Iceland. It is a paired active central volcano with Grímsvötn, and can be classified as part of the Grímsvötn-Laki volcanic system, with common fissure swarms to the south.

Standing on a volcano puts things in perspective. The earth beneath your feet is alive and restless.

Check road conditions before heading to volcanic areas. Some roads close seasonally or after weather events.
