10 State Threatened Asteroid Collisions

Disasters do not just come from the Earth, such as floods, earthquakes, tsunamis, or volcanic eruption. But there is also the threat of doom that comes from outer space: an asteroid collision.
Researchers from the University of Southampton makes the state table that is expected to be worst affected in the event of an asteroid collision. There are two reasons why these countries into "category of most endangered". Namely, the potential number of casualties and damage to infrastructure that could make the country's lame that it's almost impossible to recover.
Developed countries dominate the list. This is a list of the 10 countries most at risk: China, Indonesia, India, Japan, the United States, the Philippines, Italy, Britain, Brazil, and Nigeria.
However, that does not mean a country that did not make the list is completely free.Sweden, for example, the state is also potentially suffered severe damage to infrastructure.
Countries most severely affected by the loss of population is the United States, China, Indonesia, India, and Japan. Meanwhile, the country with the greatest potential for infrastructure damage is Canada, U.S., Japan, and Sweden.
From which this conclusion is generated? The researchers used the software (software) called NEOimpactor, 'NEO' stands for Near Earth Object program.
"The threat of an asteroid hit the Earth has been accepted as the greatest natural disaster threat facing mankind," said Nick Bailey, University of Southampton scientists who developed the software NEO, as published the Daily Mail, Wednesday, June 29, 2011 night. "The consequences of loss of human population and destruction of infrastructure is huge."
He added, noting the history of disasters caused by asteroids. "Nearly 100 years ago, in a remote area near the Tunguska catastrophe to be an eyewitness when the object that is not how big (about 50 meters in diameter) exploded in the air," he said. "Luckily there is only forest. If exploded in London, for example, a different story, everything destroyed."
Bailey explained the purpose of research done it is to give early warning - that every country - especially those at high risk - mitigate. Meanwhile, according to DailyGalaxy.com, 12-mile-diameter asteroid could potentially destroy the lives of animals and plants. Like the asteroid population is responsible destroy the dinosaurs 65 million years ago. At that time, 10-mile-diameter asteroid bombard the Earth, 25,000 stones in an hour. Its power is 100 megatons, or equal to one Hiroshima bomb to everyone on the planet.
Megabencana post it, the Earth avoid a similar tragedy because Jupiter's gravitational field protects the Earth from outer space rock exposure. (Umi)
