What happens when a nuke is detonated underwater?

At the maximum diameter of the first oscillation, a very large nuclear bomb exploded in very deep water creates a bubble about a half-mile (800 m) wide in about one second and then contracts, which also takes about a second. Blast bubbles from deep nuclear explosions have slightly longer oscillations than shallow ones.

Can a nuclear bomb evaporate water?

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.

Can you survive a nuke in water?

Originally Answered: Can you survive a nuclear blast by hiding underwater? Nope. Water, being incompressible, propagates a blast wave much more readily than air. Water would provide more protection from radiation but much less protection from a blast.

How many times has the US tested nuclear weapons underwater?

The U.S. government only tested nuclear weapons underwater three more times. In 1958, as part of Operation Hardtack, the military set off another deep water detonation and another lagoon detonation. In both cases, the devices were smaller than their predecessors, and there were few surprises in the outcome of the tests.

What would happen if we put a nuclear bomb on Earth?

This ‘aerosol’ of particles would reduce the amount of heat reaching the surface from the Sun, producing a so-called nuclear winter with huge environmental impact. The nuclear explosion would also unleash a pulse of electromagnetic energy that would wreck everything from national power grids to microchips around the world.

How long does it take for a nuclear explosion to occur?

A nuclear explosion may occur with or without a few minutes warning. Fallout is most dangerous in the first few hours after the detonation when it is giving off the highest levels of radiation. It takes time for fallout to arrive back to ground level, often more than 15 minutes for areas outside of the immediate blast damage zones.

Why did North Korea conduct a nuclear test underwater?

The military leaders who proposed the test wanted to show that their ships could ride out a nuclear attack and that the fleet was not obsolete. But the underwater test was controversial, perhaps even more so than land-based test blasts. Even nuclear scientists questioned its point.
