Iceland’s visible rift
At Þingvellir National Park, visitors can see a rift valley and fissures formed as the North American and Eurasian plates diverge along the Mid-Atlantic Ridge. Their relative spreading rate in the region is about 2 cm per year, but deformation within the rift zone accumulates and is sometimes released in episodes of faulting and earthquakes.
Þingvellir’s rift valley exposes a plate boundary on land.
