Why is Iceland spreading apart?
Because Iceland lies on the Mid-Atlantic Ridge, it is being split by the movements of the shifting tectonic plates. The plates are moving apart, one to the east, the other to the west, and both the North American and the Eurasian systems are moving to the northwest across the hotspot.
Why is Iceland growing wider each year?
The island owes its existence to a large volcanic fissure in the Mid-Atlantic Ridge, where the Eurasian and American tectonic plates meet. Even today, the country is growing by about 5 cm per year, as it splits wider at the points where two tectonic plates meet. Iceland is the least populated country in Europe.
Is Iceland growing or shrinking According to plate tectonics?
According to the latest measurements by the Icelandic National Land Survey Iceland is expanding at the rate of 2 cm (0.8 inches) each year as the eastern part of Iceland drifts to the east and the western part drifts to the west.
Why is Iceland so tectonically active?
Iceland experiences frequent volcanic activity, due to its location both on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and over a hot spot. Nearly thirty volcanoes are known to have erupted in the Holocene epoch; these include Eldgjá, source of the largest lava eruption in human history.
Will Iceland become two islands?
But will Iceland split in two? No, it will not. Iceland is being pulled apart at a rate of about 2.5 cm each year, which is quite a bit, but our volcanic eruptions help by filling up the gaps that could form. The mid-Atlantic ridge runs through Iceland and is the only place you can see it above ground.
Is the volcano in Iceland active?
The most famous and active volcano in Iceland is mount Hekla, which has erupted 18 times since 1104, the last time in 2000. Other active volcanos, measured in terms of the number of eruptions besides Hekla, are Grímsvötn, Katla, Askja and Krafla.
