The mainstream media, so to speak, is starting to pay more attention to the possible electromagnetic pulse threat that North Korea could try, especially as retaliation for a US strike. Here is the source for an article today by David Hamburg of Popular Mechanics, which was shared by Resilient Societies.
The article gives somewhat different explanations of what the E1 and E3 pulses do. The E1, it says. Might not harm cell phones or tablets or even laptops not plugged in, but probably many devices actually plugged in would be fired. There is a real question as to how many transformers could be severely damaged by an E3 pulse. And apparently some states are looking at requiring utilities to install neutral ground blockers, but these are more expensive than some activists claims.
The article maintains that an EMP-intended weapon need not be as accurate as one intended to explode near the target and could be harder to shoot down at high altitude. But it is not clear whether North Korea really has the ability to carry out this specific threat right now.
The article also links to a 2010 Oak Ridge National Laboratory report on the EMP threat and countermeasures. I visited the facility in July 2013 and took the tour available at the time and asked some questions about this issue.
Back on September 4, 2001, one week before 9/11, Popular Mechanics had run a story on localized non-nuclear magnetic flux EMP weapons, which have remained relatively little known.
As the YouTube video included above shows, National Geographic had made a video on the EMP threat in 2013, and doesn’t seem to have been taken that seriously. It may be a little over-hyped.
