DCBryan1 :Where , when , and what was the megaton amount ?
LOTS AND LOTS AND LOTS AND LOTS....Clicky linky for multi-megaton nuclear explosions

You sent me a 5:09 U-Tube video ( 3X faster ) of all " A Time-Lapse Map of Every Nuclear Explosion Since 1945 - by Isao Hashimoto"

That's fine film of nuclear detonations, but it doesn't answer the germain question of the electronic effects of High Altitude nuclear detonation .
None of those in the U-Tube film deal with "High Altitude" detonations, much less EMP effects , which is the essense of the question asked.
Thanks anyway !

They aren’t high altitude nor are they over a city, nor are they involving modern electronics.
