What was the destructive effects, blast radius, and power of Tsar Bomba?

Question

The 50 megaton nuclear device dropped by the Soviet Union in the 1960s. What would be the effects of a 100 megton device? How does this compare to the hydrogen bomb from our arsenal?

Answer 1

It would depend on air burst or ground detonation, terrain, urban density, ground type, weather conditions, and so on, the effects of any detonation include

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

Blast Wave overpressure of a 100 meg detonation the size of Tzarrina megabomb:
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....

Answer 3

Originally designed as a 100mt weapon it was reduced to the 50mt range to avoid radioactive fallout. A fission type H-Bomb it actually had an estimated yield of 57mt with a blast radius of 4.6km.

It was code named IVAN and detonated in 1961. One of only 2 reported to have been produced the remaining weapon is in a Moscow museum.

Compared to the USA which has detonated only a 25mt (top yield estimated at 30mt) weapon the Tsar was correspondingly more destructive. Since it wasn't possible to deliver it by ICBM it was never placed into production. Delivery by aircraft was to exposed to interception in the 1960s.
