How fast is a nuclear explosion in mph?

A nuclear blast wave can start at 5 times the speed of sound about 6000 km an hour. Did some rough math and came up with about 45,000 mph.

How many miles can a nuke explode?

A 1 megaton nuclear bomb creates a firestorm that can cover 100 square miles. A 20 megaton blast’s firestorm can cover nearly 2500 square miles.

How hot is a nuke?

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.

How far above a city can a nuclear bomb explode?

By default, Nukemap assumed a 150-kiloton-yield warhead would explode 1.03 miles above the city. An aerial detonation maximizes a nuclear bomb’s destructive power, since it allows the blast’s energy to spread out. If a bomb is detonated on the ground, the soil absorbs more of that energy.

How do you survive a nuclear explosion in a car?

Lie face down to protect exposed skin from the heat and flying debris. If you are in a vehicle, stop safely, and duck down within the vehicle. After the shock wave passes, get inside the nearest, best shelter location for protection from potential fallout.

What happens when a nuclear bomb is exploded?

Fireball (0.56 miles wide) — In the area closest to the bomb’s detonation site, searing flames incinerate most buildings, objects, and people. Radiation (1.24 miles wide) — A nuclear bomb’s gamma and other radiation are so intense in this zone that 50\% or more of people die within “several hours to several weeks,” according to Nukemap.

How many people would be killed by a nuclear explosion?

According to Nukemap’s casualty estimator, however, this blast would still kill about 130,000 people and injure 280,000 over the next 24 hours. The tool notes that this does not include radioactive fallout effects, among other caveats. “Modelling casualties from a nuclear attack is difficult,” it states.
