With Sunday’s test of a 100-kiloton weapon by North Korea which is claimed to be thermonuclear by the regime, the situation has intensified between the USA and North Korea. The recent test by the ‘Rogue Nation’ has shown the possibility of the electromagnetic pulse, or EMP, which could wipe out electrical grids around major parts of the US.
The tested weapon by North Korea indicates its powerful impact that could wipe out a city, however, the pulse from high altitude blast could be much more devastating with destruction reaching far wider than a city, according to the reports.
The state run news agency of North Korea warned by describing the bomb as ‘A multifunctional thermonuclear nuke with a great destructive power which can be detonated even at high altitudes for super-powerful EMP attack.’
According to the experts, the EMP blast is capable of emitting high-frequency radio waves which could knock out the electrical grids in no time, much like a sudden power surge after the overload. But the effect could be far worse as the higher the nuclear EMP blast takes place, the larger the area it can knock down.
Such blasts could create a humungous amount of chaos as it can knock down several hospitals, government agencies and break the coordination in the US leaving it paralysed.
Almost everything in the modern day the USA is dependant on electricity by one way or another. The EMP can affect the lives of millions by striking power grids which will result in no food delivery, no water purification, no banking, no telecommunications, no medicine.
The EMP impact is directly proportional to the height of the detonation. The higher the altitude the more deadlier the EMP impact. For example, blast taking place 19 miles above the centre of the USA can wipe out electricity at Kansas and Nebraska, almost all of South Dakota, and substantial chunks of surrounding states.
Theoretically, a blast from the height of 249 miles above the USA can wipe out the entire electrical system of the USA and parts of the neighbouring countries of Canada and Mexico.
North Korea has already shown its capabilities to reach the altitude with its successful satellite launches in 2012 and 2016. The experts believe the satellite launches is the test to monitor EMP trajectory.
The destruction from Nuke thermal radiation is an another matter altogether and EMP threat is increasing day by day for the USA with the rising dependency on electronics in the country.
