The most powerful thermonuclear device ever detonated, Big Ivan, AKA Tsar Bomba, exploded over Novaya Zemlya, with a force of 50 megatons, 4000 times more powerful than the bomb which was dropped on Hiroshima.
The effects were spectacular.
Despite the very substantial burst height of 2.5 Mile (4 KM) the vast fireball reached down to the Earth and engulfed the ground below it, and swelled upward to nearly the height of the release plane. The blast pressure below the burst point was 20.6 Bar (300 PSI, 21.092 kilogram-force/square centimeter) six times the peak pressure experienced at Hiroshima. The flash of light was so bright that it was visible at a distance of 620 Mile (1,000 KM), despite cloudy skies. The mushroom cloud reached a height of 40 Miles (64 KM). The blast wave was still measurable on it's third passage around the Earth.
Dropped on a city the size of London here's what would happen, the Blast wave would destroy everything within a 15 Mile (24 KM) radius, the fire ball would incinerate everything within a 55 Mile (88 KM) radius, the plane which dropped the Device(or bomb, whatever you want to call it) had to be modified a fair bit to drop the Bomb, as it was too large to fit in the bomb bay, the bomb bay doors had to be removed and the bomb lifted up with a special hoist and was painted white all over to protect it from the thermal pulse. Tsar Bomba was given a parachute too slow it's decent and give the crew more time to escape the shockwave. The parachute required so much nylon that the Soviet nylon industry was disrupted.
Ironicly despite the yield of the bomb, 97% of the total energy came from the fusion stage making it one of the cleanest nuclear bomb detonated, generating a very low amount of fallout relative to its yield.
