Revealed: Two Asteroids Crashed Into Earth’s Ocean At The Same Time
GEOLOGISTS have discovered the craters of two large asteroids they believed crashed into earth simultaneously.
Scientists from the University of Gothenburg in Sweden found the impact craters just ten miles apart in Jämtland, Sweden.
It is believed they are the world’s first confirmed simultaneous significant craters.
One of them is a huge 4.7miles wide, while the other spans 1.3miles across.
The space rocks, which struck in the sea, would have caused devastating tsunamis, and could have even wiped out some species, scientists believe.
Erik Sturkell, professor of geophysics at the university, 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 Jämtland.
“Information from drilling operations demonstrates that identical sequences are present in the two craters, and the sediment above the impact sequences is of the same age.
“In other words, these are simultaneous impacts.”
At the time Jämtland was under a shallow sea.
