Vatnafjöll at a Glance

About Vatnafjöll

Vatnafjöll is a volcanic ridge and fissure system in southern Iceland, located within the country’s Southern Region. It forms part of the broader volcanic landscape east of the Hekla volcanic massif.

The area consists of lava fields, ridges and volcanic cones created by repeated fissure eruptions over the Holocene. The terrain is typical of Iceland’s active volcanic zones and shows layers of lava flows and volcanic landforms.

Vatnafjöll has formed through volcanic activity rather than through glacial deposition or sedimentary processes, and the ridge is part of the Southern Region’s network of volcanic systems. Its proximity to Hekla places it within one of Iceland’s more volcanically active areas.

The ridge sits in southern Iceland, east of the Hekla volcano and within the island’s highland and lowland transition zone.
