by Ragnar Sigurdsson (arctic-images.com), Iceland
Almannagja- 7.7 km long, width 64 m, maximum throw is 30-40 m. It marks the eastern boundary of the North American plate. Its equivalent across the graben, marking the western boundary of the Eurasian plate is Hrafnagja. It is 11 km long, 68 m wide and a maximum throw of 30 m. Thingvellir is also renowned for its geological significance. The area is located on the Mid-Atlantic ridge, where the continents of Europe and America drift apart, causing earthquakes and volcanic activity. Standing in the Almannagja fissure, the visitor is literally situated between the continental plates.
