How big is a 1 megaton nuclear bomb?
A 1 megaton hydrogen bomb, hypothetically detonated on the earth’s surface, has about 80 times the blast power of that 1945 explosion. At the center lies a crater 200 feet deep and 1000 feet in diameter. The rim of this crater is 1,000 feet wide and is composed of highly radioactive soil and debris.
How many megatons are nuclear bombs?
Nuclear weapons vary in their destructive power. In the United States’ current nuclear arsenal, the most powerful bomb is the B83, which has a maximum yield of 1.2 megatons, making it 60 times more powerful than the bomb dropped on Nagasaki, Japan, in 1945.
How many kilotons is a megaton?
Megaton to Kiloton Conversion Table
| Megaton [Mton] | Kiloton [kton] |
|---|---|
| 1 Mton | 1000 kton |
| 2 Mton | 2000 kton |
| 3 Mton | 3000 kton |
| 5 Mton | 5000 kton |
What is a 1 megaton bomb?
Similarly, a 1 megaton weapon would have the energy equivalent of 1 million tons of TNT. One megaton is equivalent to 4.18 x 1015 joules. In evaluating the destructive power of a weapons system, it is customary to use the concept of equivalent megatons (EMT).
How many kilotons is a nuke?
In modern nuclear arsenals, those devastating weapons are considered “low-yield.” Many of the modern nuclear weapons in Russian and U.S. nuclear weapons are thermonuclear weapons and have explosive yields of the equivalent at least 100 kilotons of dynamite – and some are much higher.
How big is a 10 kiloton nuclear bomb?
about 300 m diameter
A 10 kiloton blast would produce a fireball of about 300 m diameter and would cause moderate flash burns (second degree) at a range of about 2.4 km. A 10 megaton blast would create a fireball about 4.8 km and moderate flash burns to 32 km.
How big is a 4 megaton nuclear bomb?
What if a bomb with a yield of 4 megatons – a convenient term for a blast equivalent of 4 millions of TNT, or about 200 times larger than the Hiroshima bomb – had detonated at Goldsboro? We can take a guess courtesy of NUKEMAP 3D, a nuclear blast simulation created by science historian Alex Wellerstein.
How many kilotons are in a Hiroshima bomb?
15 kilotons
The two nuclear weapons dropped on Hiroshima and Nagasaki, had an explosive yield of the equivalent of about 15 kilotons of dynamite and 20 kilotons of dynamite respectively.
How many kilotons was Chernobyl?
According to several independent studies, while the first explosion was normal – chemical, the second explosion with the burning of the prompt neutrons, it had characteristics of a nuclear explosion with a yield of 0.3 kilotons (equal to around 300 tons of TNT).
What is the largest nuclear bomb today?
With its retirement, the largest bomb currently in service in the U.S. nuclear arsenal is the B83, with a maximum yield of 1.2 megatons….B53 nuclear bomb.

Is Hiroshima still recovering?
A moment’s silence was held at 08:15, the exact time the bomb was dropped on the city. “On August 6, 1945, a single atomic bomb destroyed our city. Rumour at the time had it that ‘nothing will grow here for 75 years,'” Mayor Kazumi Matsui said. “And yet, Hiroshima recovered, becoming a symbol of peace.”
