ASTEROIDS COULD DESTROY CITIES



GEOLOGY Scientists have made a list of the number of asteroids that hit Earth in 2000- 2013. A total of 26 times, our world was struck by violent explosions, which were caused by asteroids.
The count demonstrates that asteroid impacts are not rare, but it also shows us how often we should expect asteroid impacts that could ruin entire cities. According to the scientists, an impact of this type takes place
every 100 years. The latest asteroid of this force hit the Russian city of Tunguska in 1908. The asteroid had a 45 m diameter and an explosive energy of 5 megatonnes (corresponding to 5,000 kilotonnes).
The impacts of the report ranked between 1 and 600 kilotonnes, as measured by a global network of sensors. In comparison, the Hiroshima nuclear bomb of 1945 had an explosive power of 15 kilotonnes.
