Update!

The mass estimates have gone up from 10000 kg to 10000000 kg (see:. nasa website). This seems like an absurd update, but in size it means that the object was only 10 times bigger than previous estimates (10 to the power 3 = 1000).
This also means that the equivalent energy released could be as high as 250 kiloton TNT.

This is equal to 17 Hiroshima bombs...

Why did we not see more destruction?

Several factors:
1) The energy was not released in 1 go. It was released during its flight...
2) The energy was released somewhere between 10 and 30 km above ground...
