#1 Shipman, say it ain’t so!

#2 It would also wipe out 100% of North Koreans.

#3 File this with the "World will end in 2020 due to Man Made Global Warming". Shhhhhh.

Note 1. The Russians and Chinese already have the EMP capability.
Note 2. Has 90 percent of the Puerto Rico population died off yet (the mayor of San Juan is not a valid data source).
Note 3. Seems we survived a long time in history without electricity without a major die off.

#4 P2k, agree except there is the caveat that we in the US have probably lost 80% of the skills necessary to survive without electricity.

#6 The surviving 10% will quickly adopt paper ballots.

#7 Democrat vote to go up 90%

#8 Democrat vote to go up 90%

How? If the lights are out, the Russian's social media ad buys and voting machine hacking will be ineffective...

#9 all those dead people's votes.

#10 There are three grids in the Lower 48 states: the Eastern Interconnection, the Western Interconnection — and Texas.

The Texas power grid is seperate from the rest of the US. They can sever connections to the other grids and function just fine.

Another reason to move to Texas.

#13 A North Korean Nuclear EMP Attack? … Unlikely

"Size Matters

This is an instance where size does matter: the larger the nuclear explosion, the larger the affected area. While technical reports and papers on EMP from nuclear detonations are mostly classified, there is a paper by D. Hafemeister of California Polytechnic Institute that provides sufficient detail to derive a simple rule of thumb on the relationship between affected distance and nuclear device yield. The paper makes some simplifying assumptions:

- The detonation is spherically symmetric (which may not always be the case);
- The Earth’s magnetic field is not accounted for;
- Prompt gamma rays account for 0.3 percent of the total energy of the explosion and are emitted within the first 10 nanoseconds of detonation;
- About 0.6 percent of the prompt gamma rays produce relativistic electrons that constitute the E1 component of the EMP; and
- The electric field damage threshold is 15,000 volts/meter or higher in the E1 component.

Plugging in the numbers and presuming these assumptions are appropriate, the rule of thumb [My favorite kind of rule, as I only have to archive (2) rules at any given time.] is surprisingly simple: D = Y, where D is the maximum damage distance expressed in kilometers and Y is the yield of the blast in kilotons. So, a 20 KT bomb detonated at optimum height would have a maximum EMP damage distance of 20 km; a 1 MT (1,000 KT) bomb would damage out to 1,000 km. The largest North Korean test to date has been estimated to be about 20 KT."

#14 You set that one up pretty well, BP.
