Today, I want to share with you the story of Tsar Bomba, the King of all bombs.
Tsar Bomba, also known as Big Ivan, was the largest nuclear weapon ever constructed or detonated. Built by the Russians in 1961, it was designed to have the firepower of 100 million tons of TNT. But, in order to reduce the nuclear fallout in their own territory, the firepower was reduced to 57 million tons of TNT. To put that in perspective, the power of this bomb was five times greater than all the TNT used in World War II (including both atomic bombs dropped over Japan!) Luckily, the bomb got 97% of its energy from from fusion reactions. Had it not, it would have increased the world's total fission fallout since the invention of the atomic bomb by 25%!
The detonation of this bomb was incredible. The cloud mushroomed up and continued to grow and grow. The fireball from the blast, though detonated in the sky, nearly touched the ground.According to the Nuclear Weapon Archive:
Despite the very substantial burst height of 4,000 m (13,000 ft) the vast fireball reached down to the Earth, and swelled upward to nearly the height of the release plane. The blast pressure below the burst point was 300 PSI, six times the peak pressure experienced at Hiroshima. The flash of light was so bright that it was visible at a distance of 1,000 kilometers, despite cloudy skies. One participant in the test saw a bright flash through dark goggles and felt the effects of a thermal pulse even at a distance of 270 km. One cameraman recalled:
The clouds beneath the aircraft and in the distance were lit up by the powerful flash. The sea of light spread under the hatch and even clouds began to glow and became transparent. At that moment, our aircraft emerged from between two cloud layers and down below in the gap a huge bright orange ball was emerging. The ball was powerful and arrogant like Jupiter. Slowly and silently it crept upwards.... Having broken through the thick layer of clouds it kept growing. It seemed to suck the whole earth into it. The spectacle was fantastic, unreal, supernatural.
Another observer, farther away, described what he witnessed as:
... a powerful white flash over the horizon and after a long period of time he heard a remote, indistinct and heavy blow, as if the earth has been killed!
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. The atmospheric disturbance generated by the explosion orbited the earth three times. A gigantic mushroom cloud rose as high as 64 kilometers (210,000 ft).
Despite being exploded in the atmosphere, it generated substantial seismic signals. According to a bulletin of the U.S. Geological Survey it had seismic magnitude mb = 5.0 to 5.25.

People 120 miles from the blast site reported third degree burns. The temperature at the epicenter of the blast reached 1 million degrees Celsius. The Russians had succeeded in creating a sun on the earth!
Here's a video of the explosion:
While all of this is a scary piece of history, as writers it is important for us to know, remember and share.
