That is, until one of them googled "safety nuclear bomb how shelter" from the beach — and found a Business Insider article titled " If a nuclear bomb goes off, this is the most important thing you can do to survive.

Our story advises going inside if there's a nuclear explosion , which the couple said they then did. But that story is about what to do after a nuclear weapon blows up by surprise, such as in a terrorist attack — the goal is to limit exposure to radioactive fallout that arrives minutes after a detonation.

It does not address how to act if there's an incoming intercontinental ballistic missile launched by a nation like North Korea. As Hawaii's false alarm suggests, the latter may come with a few minutes to a half-hour of warning. But Buddemeier, who has worked for more than 15 years with federal, state, and local stakeholders on response plans to nuclear-disaster scenarios, says there are some important differences that can improve your chances of survival.

Here's how to act and where to take shelter if you get an alert about an ICBM or other nuclear threat. Knowing what you're trying to avoid can help keep you safe. All nuclear blasts are marked by a handful of important effects:. The first three arrive almost instantaneously, as they travel at light-speed — though thermal radiation can last several seconds and inflict severe burns miles from a blast site. The final two effects travel close together, but the air blast goes much farther.

It causes the most damage in a nuclear explosion by tumbling vehicles, toppling weak buildings, and throwing debris. The majority of fallout arrives last, as it's lofted high into the sky and sprinkles down. There are two upshots: Going inside can greatly limit or even block these devastating effects, and a nuclear weapon's power is not infinite but limited to the device's explosive yield.

That makes a single blast or even a limited nuclear exchange survivable for most people. Arms-control experts suspect a nation like North Korea may have missile-ready warheads that would explode with 10 to 30 kilotons' worth of TNT.

That ranges from less than to roughly twice the yield of either nuclear bomb the US dropped on Japan in The worst destruction, where the chances of survival are least likely, is confined to a "severe damage zone. North Korea may be capable of launching a miniaturized thermonuclear weapon that yields kilotons of blast energy. Yet even for an explosion that big, Buddemeier said the severe damage zone would be limited to a radius of about one mile.

Not all structures are created equally, though, and you may want to move after the air blast has passed. If it's got a basement, go in there. Nothing is guaranteed, and you don't know where the weapon will likely go off, but these kinds of structures do much better against blast, heat, and radiation than anything else.

This blindness is temporary, only lasting for a few seconds or few minutes , but for that brief time it could make people more vulnerable to hazards such as rubble. During the day, the blinding effects of a nuclear flash can reach 10 miles from the blast zone. At night, those effects extend even farther. Sheltering in a building is extremely important for surviving the next stage of a blast: the heat wave.

The thermal blast of a five-megaton warhead the high end of modern intercontinental ballistic missiles will be around 15 miles. That blast is so powerful that it can sear away pain nerves while causing third degree burns. Simply sheltering in a building, preferably underground, can mitigate the worst effects of this heat wave. A building could become dicey during the air blast that follows the fireball, however. The air blast in the moderate damage zone will likely cause another wave of injuries even for those who sought shelter, but it will be worse for anyone who stayed outside or attempted to flee by car.

Like a tornado or an earthquake, getting to a secure location in the middle of a building is safer than the alternative. After the air blast comes the radiation, and a building is also likely to provide the most protection.

The light damage zone is on the very fringes of the explosion. It might pop the roof of a building. Surviving the initial blast requires some luck even inside a building, but staying safe after the initial detonation requires patience. Around 15 minutes after the initial blast, this fallout will begin to move through the atmosphere and pepper the ground. But new models now predict that even a very limited nuclear war would have drastic knock-on effects for global agriculture and dire consequences for life on Earth.

A blast from a modern nuclear weapon would produce a vast amount of energy almost instantly. The effects would be devastating. First, a blinding flash of light and radiation in the form of heat from the initial explosion would produce temperatures as high as that of the Sun. Wood, plastics, fabrics and flammable liquids would all ignite. This would almost immediately be followed by the blast wave, moving at several times the speed of sound. A wall of compressed superhot air, the wave would gather up rubble and anything moveable, levelling all buildings within the blast zone and killing everyone in its path for several kilometres.

Within 20 to 30 minutes, a shroud of highly radioactive ash would begin to fall, blanketing both the blast site and the surrounding area, tens of kilometres downwind, and very quickly killing anyone caught outdoors who had somehow managed to survive the initial explosion. For people outside the blast zone, the situation would also be grim.

All electronic equipment would cease to function as the electromagnetic pulse fried every electronic circuit. No phones, internet, computers or cars would work. Hospitals would be quickly overwhelmed, with the vast majority of the population needing some kind of medical care. Food would disappear as logistical supply trains stopped working. What little there was would be contaminated by the radioactive fallout, along with any water. In the case of a nuclear conflict between India and Pakistan, for example, it is estimated that between 50 million and million people would die.

Those would be the initial, local effects of a nuclear conflict on a population.
