how much can an atomic bomb blow up?(like a city, a town?)?

Question

i just was curious. oh one more thing, whats the biggest bomb there is?

thanks for answering!

Answer 1

well radius can be huge... Depend of the bomb size...

The biggest one is our "Nicky Dicky", 480 megatons...
This is secret info, of course
;)
PS
we keep that weapon on space station and it is earth defence
project established 15 years ago

Answer 2

Depends on the physicality of the target. For example, Hiroshima was surrounded by mountains. This was extremely optimal for the fission bomb to start a "fire-storm" and increase size of the "fire ball" and the blast radius. Thermonuclear weapons can sink entire islands and devastate large areas, such as a city. Its power can exceed several megatons. (take note that a 10-KILOTON bomb would cause "moderate" damage to a 24km radius, and a megaton=1000kilotons). The lag est nuclear bomb was the Tsar.

Answer 3

Imagine Hiroshima but 4000 times bigger.This was the size of the Tsar Bomba nicknamed Ivan detonated above the pacific by the Russians.

Answer 4

The device offically designated RDS-220, known to its designers as Big Ivan, and nicknamed in the west Tsar Bomba was the largest nuclear weapon ever constructed or detonated.

In its test, a shock wave in air was observed at Dickson settlement at 700 km; windowpanes were partially broken to distances of 900 km. All buildings in Severny (both wooden and brick), at a distance of 55 km, were completely destroyed. In districts hundreds of kilometers from ground zero, wooden houses were destroyed, and stone ones lost their roofs, windows and doors; and radio communications were interrupted for almost one hour.

Answer 5

the effects would depend on the yield. the effects of any detonation include:

Primary shockwave
Thermal Radiation Effects
Direct Nuclear Radiation Effects
Radioactive Fallout
Electromagnetic Pulse

Blast Wave overpressure of a 100M detonation the size of Tzarrina megabomb (the largest nuke ever constructed):
30 psi: 5.64 miles
10 psi: 10.35 miles
4 psi: 18.13 miles
2 psi: 26.71 miles
0.5 psi: 68.52 miles
0.2 psi: 140.36 miles

Key to the Damage:
15 psi Complete destruction of reinforced concrete structures, such as skyscrapers, will occur within this ring. Between 7 psi and 15 psi, there will be severe to total damage to these types of structures.
5 psi Complete destruction of ordinary houses, and moderate to severe damage to reinforced concrete structures, will occur within this ring.
2 psi Severe damage to ordinary houses, and light to moderate damage to reinforced concrete structures, will occur within this ring.
1 psi Light damage to all structures, and light to moderate damage to ordinary houses, will occur within this ring.
0.25 psi Most glass surfaces, such as windows, will shatter within this ring, some with enough force to cause injury.

I didn't calc. thermal radiation effects, fallout or EMP damage, but suffice it to say, i'd predict global impact winter.... BTW, the 50M that the Soviets detonated was not set to its maximum of 100M due to their concern of the global impact such a detonation would bring, not the size of the plane.
