PictureExplosion of the Tsar bomb at the Novaya Zemlya Island
This picture is showing the devastating effects of the Tsar bomb on the Novaya Zemlya Island. It completely destroyed 40 around from the point which it was detonated and also it affected 20 more miles around causing severe destructions which in total we can say that it affected 60 miles of the area in which this bomb was detonated.

In this Picture we can compare the last man made bomb (Tsar bomb) with the rest of all bombs. We can see that the Hiroshima bomb that destroyed almost everything of that city is just an small portion of the destructive power of the Tsar bomb. Although we need to take in mind that the Tsar bomb is an old bomb that was builted from the soviet union which means that nowadays people can build bombs with a destructive power much stronger than this bomb. If they do this and a conflict starts and we this countries decide to launch their nuclear missiles to another countries; this will mean the end of our world because of all the radiation that it is going to cause and although all the places are going to turn inhabitable by any kind of living thing by the radiation.

In the worst scenario this bomb will be builted again and it will be used for Lima. This means that it will destroy about 60 miles of all lima. Although we need to know that the radiation that this explosion will leave to the area affected will turn the area unhabitable because we are not prepared for a nuclear bomb to be detonated in this place.
Lima is an small place so small bombs can affect in a big portion our capital. In conlcuision 60 miles can almost destroy an important area in lima. Although, in the picture over the video of youtube about the Tsar bomb and below the picture that is below this text you can see a picture which demonstrates how much a fraction of the power of the Tsar bomb can affect lima (Peru).

This picture shows the area that the Tsar bomb would affect divided by 40 which means that 50MT (megatons) divided by 40 and turned into kiltons is 1205 KT of destructive nuclear power over lima. (Imagine this with 50,000 KT of destructive power over lima which is the real destructive power of the bomb)
