EMP attack can be brought upon the humanity by a powerful solar flare or an enemy. Nonetheless, the threat is present and everyone must be aware of it.
If such an attack happened, it would have a negative impact on the power grid. People would be left without electricity, food, water and other supplies. Dissatisfaction with living conditions would lead people to engage in riots and chaos.
At the moment, the strategy to fight such attack is being devised by the Congress, Homeland Security, the Pentagon and the White House.
According to US researchers, a strong electromagnetic pulse (EMP) from solar flares would cause damage of up to $2.6 trillion.
People would be without the electricity for months.
There was a danger of a devastating solar storm in 2012. The dangerous solar storm could actually strike the Earth in 2022. According to scientists, there are 12% chances that it is going to happen.
In addition to this, the US is concerned because both Russia and China have EMP weapons in their possession. This notion is frightening because the US is not in good relations with these countries.
Either way, a nuke attack or a solar storm could set off a catastrophic electromagnetic pulse.
It remains to be seen whether these predictions are justified or not.
