Þingvellir National Park (pronounced Thingvellir)  is a national park in South Iceland and a UNESCO World Heritage Site. The park is home to the world’s longest running Parliament, first established in 930 AD, and also has a dramatic landscape formed as a result of sitting along the border between the North American and European tectonic plates.
Diving in the Tectonic Plate Gap
Between Europe and America!
According to the continental drift theory the Eurasian and North American tectonic plates are continuously drifting apart with great forces under the gaping rifts. As the plates diverge, linear fractures, known as fissures form due to stresses created by the tension that builds up as the plates move away from each other.
The Bridge between two continents at Sandvík is a small footbridge over a major fissure which provides clear evidence of the presence of a diverging plate margin. The bridge was built as a symbol for the connection between Europe and North America

Laki or Lakagígar is a volcanic fissure in the south of Iceland, not far from the canyon of Eldgjá and the small village Kirkjubæjarklaustur. Lakagígar is the correct name, as Laki mountain itself did not erupt, but fissures opened up on each side of it. Lakagígar is part of a volcanic system centered on the Grímsvötn volcano and including the Þórðarhyrna volcano. It lies between the glaciers of Mýrdalsjökull and Vatnajökull, in an area of fissures that run in a southwest to northeast direction.
The system erupted over an eight-month period between 1783 and 1784 from the Laki fissure and the adjoining Grímsvötn volcano, pouring out an estimated 14 km3 (3.4 cu mi) of basalt lava and clouds of poisonous hydrofluoric acid and sulfur dioxide compounds that killed over 50% of Iceland’s livestock population, leading to a famine that killed approximately 25% of the island’s human population.
The Laki eruption and its aftermath caused a drop in global temperatures, as sulfur dioxide was spewed into the Northern Hemisphere. This caused crop failures in Europe and may have caused droughts in India. The eruption has been estimated to have killed over six million people globally, making the eruption the deadliest in historical times.
