A nuclear bomb. Decibel meters set 250 feet away from test sites peaked at 210 decibels. The sound alone is enough to kill a human being, so if the bomb doesn't kill you, the noise will. Fun fact!
General Leslie Groves “Memorandum on the Trinity Test” (18 July 1945) to the Secretary of War makes the following comment: The sound was heard to the same distance in a few instances but generally to about 100 miles.
Nuclear explosions are amongst loudest phenomena on Earth. Their loudness ranges roughly from 240 dB to over 280 dB.
Tsar Bomba (224dB)
The Hiroshima and Nagasaki bombs of 1945 destroyed cities in an instant – but the Tsar bomb was 3,300 times stronger than that and is considered the strongest sound every produced by mankind, with the most reliable figure suggesting it clocked at 224dB.
A nuclear bomb explosion has been reported to be 240 to 280 dB+. A sound level meter set 250 feet away from test sites peaked at 210 decibels. At the source, the level is reported to be from 240 to 280 dB+.
The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.
People cannot see, smell, feel, or taste radiation; so you may not know whether you have been exposed.
Depending on its impact radius, even a Tsar bomb cannot destroy a whole country. Only a small country such as Vatican City or Monaco with land areas of 44 ha and 202 ha respectively can be completely destroyed using a nuclear weapon.
The Sun emits the equivalent of 4 × 1026 J of energy each second, by comparison, some 2 billion times more energy than the Tsar Bomba gave off.
The air blast from a 1 KT detonation could cause 50% mortality from flying glass shards, to individuals within an approximate radius of 300 yards (275 m). This radius increases to approximately 0.3 miles (590 m) for a 10 KT detonation. up to millions of degrees.
Life will survive after a nuclear war, even though humans may not. A "nuclear winter" would see temperatures plummet, causing massive food shortages for humans and animals. Radiation would wipe out all but the hardiest of species.
At a distance of 40-45 miles, a person would have at most 3 hours after the fallout began to find shelter. Considerably smaller radiation doses will make people seriously ill. Thus, the survival prospects of persons immediately downwind of the burst point would be slim unless they could be sheltered or evacuated.
Stay inside. Close and lock all windows and doors. Go to the basement or the middle of the building. Radioactive material settles on the outside of buildings; so the best thing to do is stay as far away from the walls and roof of the building as you can.
Right now the chance of a nuclear war is very low, but even a very low chance of such destruction is much, much too high. Even when we're faced with a tiny risk of a colossal tragedy, there are still things we can do, says Sandberg. “Many people are feeling super depressed right now.
The six most likely target cities in the US are as follows: New York, Chicago, Houston, Los Angeles, San Francisco, and Washington, DC. These countries will stay prepared to combat any type of nuclear attack shortly.
A new study sponsored by the American Physical Society concludes that U.S. systems for intercepting intercontinental ballistic missiles cannot be relied on to counter even a limited nuclear strike and are unlikely to achieve reliability within the next 15 years.
#1: Tsar Bomba (1961)
The explosion, yielding 50,000 kilotons, obliterated an abandoned village 34 miles (55km) away and generated a 5.0-5.25 magnitude earthquake in the surrounding region. Initially, it was designed as a 100,000 kiloton bomb, but its yield was cut to half its potential by the Soviet Union.
"The warhead at the front of it has a yield of between 300 and 800 kilotonnes [of TNT equivalent]. "Three hundred kilotonnes is enough to destroy Washington or London or Paris.
The intense heat from the detonation was capable of causing third-degree burns at a distance of 62 miles from ground zero. The shock wave was felt as far away as the Dikson settlement located 430 miles away, and windows shattered at a distance of 560 miles.
The Tsar Bomba (Russian: Царь-бо́мба) (code name: Ivan or Vanya), also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested.
Russia's Tsar bomba: World's most powerful nuclear weapon of mass destruction. The Tsar bomba exploded about 4 km above the ground and reportedly produced a mushroom cloud 60 km high.
It would take just three nuclear warheads to destroy one of the 4,500 cities on Earth, meaning 13,500 bombs in total, which would leave 1,500 left.
Immediately after you are inside shelter, if you may have been outside after the fallout arrived: Remove your outer layer of contaminated clothing to remove fallout and radiation from your body. Take a shower or wash with soap and water to remove fallout from any skin or hair that was not covered.
Initially, most of this energy goes into heating the bomb materials and the air in the vicinity of the blast. Temperatures of a nuclear explosion reach those in the interior of the sun, about 100,000,000° Celsius, and produce a brilliant fireball. The fireball shortly after detonation.
Water provides excellent shielding against ionizing radiation. While the radiation from the initial detonation is setting everything nearby on fire, the surface of the water will harmlessly evaporate.
