Double Whammy: 2 Meteors Hit Ancient Earth At The Same Time

It's not altogether uncommon to hear about double rainbows, but what about a double meteor strike? It's a rare event, but researchers in Sweden recently found evidence that two meteors smacked into Earth at the same time, about 458 million years ago.

Researchers from the University of Gothenburg uncovered two craters in the county of Jämtland in central Sweden. The meteors that formed the craters landed just a few miles from each other at the same moment, according to Erik Sturkell, a professor of geophysics at the University of Gothenburg and one of the scientists who is studying the newfound craters.

When the meteors slammed into Earth, Jämtland was just a seafloor, about 1,600 feet below the surface of the water. One of the craters left by the meteors is huge, measuring 4.7 miles across. The other, smaller crater — which is only about 2,300 feet across — is located just 10 miles from its larger neighbor. [Meteor Crater: Experience an Ancient Impact]

After analyzing information collected from a drilling operation, the researchers determined that the impact craters were formed at the same time. The information revealed identical geological sequences, or layers of rock, inside each crater. The sediment that accumulated inside the craters over the subsequent millennia also dates back to the same time, according to Sturkell.

"In other words, these are simultaneous impacts," Sturkell said in a statement. The meteors likely crashed to Earth following the collision of two large asteroids in the asteroid belt between Mars and Jupiter some 470 million years ago, he added.

When the meteors crashed into Earth, they displaced the water underneath them...

I've gotta wonder how rare it is. One of the few impacts we've ever witnessed was a multiple impact.

It seems strange to me that they would create craters with 1600' of sea to get through first. Does this sound odd to anyone else?

That’s one of them, and one of the few admitted to be impact in origin.
That it might be part of a crater chain is where the scientists go ga-ga and get upset.

(Panther Mountain in NY is an impact structure revealed in inverse relief. That it is an impact structure is controversial, they so far have indicated no interest in studying it. At all, ever.)

The Eltanin impact crater is about 2 million years old, and was found about 50 years ago, in the southern ocean, off Antarctica.

I believe the southern Appalachians, ending in the Red Mountain of Birmingham, AL is a skewed impact crater........................

So to date two craters to the same time, the science community will spend the next several years frothing over it and trying to discredit the ones reporting it.

Hey those "scientists" have to do SOMETHING to look like they're relevant and keep those grants coming!

It would appear so, there are road cuts that appear to go through impact breccia.
Though with Wetumpka crater right there, the impetus to look for anything else in the area is lessened.

That may be part of it.
Don’t know.
But it really does seem that there is some bizarre block to the thought that craters chains can happen on earth.

Nah.

Probably two pieces of the same thing.

Also, the Berringer Crater (Meteor Crater) in AZ was produced by an object about 100 meters wide, tiny compared with these really big ones. The crater is 3/4 of a mile across.

Meteor Crater

"Scientists refer to the crater as Barringer Crater in honor of Daniel Barringer, who was first to suggest that it was produced by meteorite impact.[4] The crater is privately owned by the Barringer family through their Barringer Crater Company, which proclaims it to be "best preserved meteorite crater on Earth".[5][6]"

Water, being incompressible, transmitted a dulled but effective impact.

Exactly. For example while the Chesapeake Meteor strike of 34 mya was 60 miles in diameter from Norfolk north, there was a 9 mile diameter crater left off Toms River in NJ, plus the 50 or 60 mile diameter crater in Russia called Popogai. All at roughly the same time, but perhaps not the same hour or day. All together they managed to change earth conditions enough to cause a 30% die off. On the other hand the recent Shoemaker-Levy bombardment of Jupiter was very quick.
