New Study Shows Asteroids Strike More Often
News Link
A new study shows that asteroid explosions in the atmosphere with a force greater than a nuclear bomb happen twice per year. Since 70% of the earth is covered by oceans, most are not observed by people. Perhaps 10% of the earth's surface is inhabited by people. That works out to about once per decade over inhabited areas. The last one observed was over Russia last year, which injured over 1,000 people.
