Don't know. But not to worry lah, Sinkie Land is safe.After the Tsar Bomba, was there anything else tested?
The Soviet Union has built the largest thermonuclear bomb in human history so far, named the Tsar Bomba.
It has a fireball radius was 2.3 km, and a radiation radius is 7.49 km. Its Air blast radius is 12.51 km.
The heat from its detonation was capable of causing third-degree burns up to a distance of 62 miles from ground zero. Its shock wave was felt by the people as far away as 692 km, while window glasses up to 900 km were shattered.
Depending on its impact radius, even a Tsar bomb cannot destroy a whole country. Only a small country such as Vatican City or Monaco with land areas of 44 ha and 202 ha respectively can be completely destroyed using a nuclear weapon.
