Researchers from the University of Gothenburg have found that two craters that were earlier discovered in Sweden were created by two meteor impacts about 458 million years ago. The craters were discovered in Jamtland of Sweden.

While providing more information on the double meteor impact, Erik Sturkell, professor from Department of Earth Sciences at the University of Gothenburg, said that when the two meteorites hit Jamtland, it was about 1,600 feet under the water.

According to reports, one of the discovered craters is huge and has a diameter of about 7.5 kilometers, while the second one is about one tenth of the first crater’s size. The craters are separated by approximately 16 kilometers.

Sturkell said, “Around 470 million years ago, two large asteroids collided in the asteroid belt between Mars and Jupiter, and many fragments were thrown off in new orbits. Many of these crashed on Earth, such as these two in Jamtland.”

According to Sturkell, data gathered after drilling operations suggested that there are some identical sequences in the two discovered craters. When the powerful meteors hit the region covered with water, the water retreated from the craters. After some seconds, the water returned to its original form.

Researchers have discovered about 90 meteor impacts in Kinnekulle, which is located in Västergötland province of Sweden. About many decades ago, scientists had found a strange red limestone slab in a Swedish quarry. The slab had contained meteorite fragments.
