Botsvatn Lake and Beyond, Tjornes Fracture Zone, North Iceland

by Jon Harrington

This image looks westward from atop the scarp of the Husavik-Flatley Fault. The right lateral transform fault forms the southern boundary of the Tjornes Fracture Zone, linking Iceland's Northern Rift Zone to the Mid-Atlantic Ridge. The Botsvatn lake forms in a large pull-apart basin, is in such weather conditions presents a beautifully smooth surface to reflect skyline beyond. Beyond Husavik we gaze across Skjalfandi or "trembling" Bay and onto the mountains of Látraströnd. The fault is last known to have ruptured in 1872 and presents a significant hazard to the town of Husavik, visible in the image.
