Iceland is sitting on the Mid-Atlantic Ridge, which separates the North American and Eurasian tectonic plates. These tectonic plates are constantly moving, pulling away from each other, so the space between them is filling up with magma, which rises in the form of volcanic eruptions. Because the Mid-Atlantic Ridge goes all the way through Iceland, there are about 130 volcanoes on the island and about 30 of them are active. The most recent volcanic eruption was on March 19. It was the Fagradalsfjall volcano that erupted. And the eruption is so vibrant that it can be seen glowing from space.
