The last major impact was the Tunguska Event, which took place in Siberia in 1908. It was a meteor or comet 100 meters across and it exploded 5-10 km in the air with the explosive force of 10-15 megatons of TNT. For comparison, the most powerful nuke the US ever tested was 15 megatons. The area was uninhabited, but it leveled about 80,000 trees.
Conclusion: Space has it out for Russia.
