Trajectory Unclear: Feb 2013 Asteroid Will Be Within Thousands of Miles of Earth; Impact Would Be As Big As Siberian Tunguska Event; 1000 Times More Powerful Than Hiroshima
March 4th, 2012
In the history of the solar system, and even in human history, there are clear records of extraordinary and devastating catastrophes… On the landscapes of other planets, where the records of the past are better preserved, there is abundant evidence of major catastrophes. It’s all a matter of time scales. An event which is improbable in a hundred years, may be inevitable in a hundred million years. Even on the Earth in this century there have been bizarre natural events.

On June 30, 1908 an incoming meteor exploded approximately 5 miles above Siberia. The force of the air burst explosion, estimated at between 15 and 30 megatons, or about 1000 times bigger than the atomic bomb that destroyed Hiroshima, was so powerful that it annihilated everything in an 830 square mile area, and reports suggest that that explosion was heard up to 1000 miles away. Because of the remoteness of the impact zone, the Tunguska Event over Siberia had very little effect on the human population in the region, but the destruction of some 80 million trees in the area shows just how powerful a blast was created.
Should a Tunguska type event occur on our planet today, especially over a populated metropolitan area, millions would be killed instantly, with many millions more being affected by the social and economic reverberations that may result from the catastrophe.
According to NASA, there is a distinct possibility that an asteroid recently identified by star gazers in Spain could hit Earth around February 15, 2013. Based on its size and trajectory, it’s estimated that the 60 to 100 meter wide asteroid, dubbed 2012 DA14, could be similar in scope and devastation to Tunguska should it enter our atmosphere.
Scientists aren’t exactly sure where on Earth the impact would occur, but they are sounding proximity warnings now:
