This is how powerful the Tsar Bomba would have been over America
In the heights of the Cold War, Soviet First Secretary Nikita Khrushchev banged his shoe against his desk as he vowed to show America at the United Nation General Assembly in 1960. The following year, on October 30th, the most massive nuclear explosion ever was detonated over Severny Island.
The 50-megaton, 60,000-pound hydrogen bomb was said to have been 1,570 times larger than the combined energy of the nuclear devices dropped over Hiroshima and Nagasaki, 10 times the collective destructive power of every conventional weapon ever used in WWII, and it alone accounted for 10 percent of all nuclear yields ever.
The mushroom cloud of the blast soared up 40 miles high (seven times the height of Mount Everest) and had a 59-mile-wide cap. The blast was so incomprehensibly large that it's nearly impossible to contextualize just how devastating it would have been if detonated over American soil.
To put all of this into perspective — and much to the delight of Yankees fans — let's measure the hypothetical blast using today's pitcher's mound at Oriole Park in Baltimore, MD, as a point of reference.
The initial blast would have decimated the entire city and everything within 12 miles. The mushroom cloud, with a radius of 29.5 miles, would have stretched all the way into Washington D.C. The heat from the blast would have extended out 62 miles, and would have left everyone in Dover, Delaware with third-degree burns.
According to NukeMap, roughly 1.4 million people would have been killed immediately and the nuclear fallout would have made its way through Philadelphia, PA and into Trenton, NJ. Shockwaves reached 430 miles, which would have put it past Cincinnati, OH. Windows would be shattered up to 560 miles miles away, reaching Chattanooga, TN.
With a height of 40 miles, the mushroom cloud would have been visible from 564.5 miles. That means everyone in the outskirts of Atlanta would have been able to see it. The fireball was visible from 620 miles away, which would have meant everyone in Chicago would be witness to it.
