An old ring-shaped structure in southern Alberta, Canada, probably formed when a Meteor into the Earth, producing a 5-mile wide (8 miles) craters smash. Enough energy to a region that would produce to destroy area in New York City, researchers say the effects.
This is a card that you may create city structure and the shape of the crater bow by a gigantic meteorite. Meters above the sea level shows color variations.
A geologist discovered the structure near the village in the town of bow, although time and glacier undermine in particular the character of the ancient meteorite strikes. Scientists can not say with certainty that a meteorite of bow city crater created, but seismic and geological findings support this idea.
"Effects of this magnitude would kill everything for pretty far," Doug Schmitt, a stone-physics at the University of Alberta, Canada, said in a statement. If the strike happened today, the city of Calgary, the 125 miles (200 km) to the Northwest, would be "completely fried" and in Edmonton, the 300 miles (500 km) Northwest, "each window would have been blown", he added.

Researchers say that the collision occurred over the last 70 million years. Disintegrated in the meantime about a 1-mile deep (1.5 km) layer of the sediment, making it hard to grasp the exact date when an object out of the crater carved.
Links are only the "roots" of the crater, a semicircular Groove with a point in the middle. The crater was strong enough probably 1 to 1.5 miles (1.6 to 2.4 km deep) - to decimate the most lives in the area, the researchers said. The object that would have sprayed debris pummeled many, from the crater could have affected all over the world, possibly for decades, she said.
Geologist Paul Glombick discovered site effects in 2009, as he was to map geological area of the Alberta geological survey. Glombick discovered the strange structure in existing geophysical log data from the oil and gas industry. The Alberta geological survey contacted Schmidt and his colleagues, who confirmed the structure with seismic data from the industry.
The discovery was detailed online ahead of print in the journal Meteoritics & planetary science.
