New York Nuclear PSA what to do in case of an attack

SFOGuy says...

I immediately wondered that; a low yield dirty bomb, at say, the UN on the Upper East Side would be a different EMP profile, I presume, from a higher yielded ship born bomb inside, say, a container which had cleared customs in Pakistan, and that would be different from a high altitude air burst, right? So, and the physics seems calculable if annoyingly in my past--you should be able to calculate a range of EMP from various yields?

The "Quora" answers are: a ground-based (ship based?) lower yield weapon has EMP effects of note to the 3 mile range.

An airburst would be a different issue. "Starfish Prime”. In this high altitude nuclear test, carried out in 1962, a 1.44 Mt warhead was detonated at a height of 400 km. Electrical damage, including burning out hundreds of street lamps was caused in Hawaii - about 1500 km from the point of detonation.

By contrast there was no direct blast damage at all at that range.

The maximal electric fields induced in the Starfish Prime EMP in Hawaii were estimated at 6 kV/m. At high latitudes the value could easily be ten times higher.

For electrical equipment to be damaged by an EMP from a nuclear detonation, the detonation point must be above the visual horizon.

A large yield weapon detonated 400 km above Kansas would have an EMP that extended across the entire continental US, but the ground intensity pattern of that EMP would be peaked towards the South of ground zero, it would not be symmetrical."

Sad that the article and @StukaFox both forgot the emp, that kills all electronics, making your car your tomb if it was made after 1980.
A car is only a decent shelter if it’s at the bottom of an underground parking structure that doesn’t collapse in the blast.
Cars are not escape vehicles in this scenario. There won’t be many erratic drivers, like the article claimed, because any car with a computer chip will be dead.

I think it's just a hideaway. Heck, (he or she) didn't even move any furniture in! Like, not even a lamp!

It's a Critter Christmas

Initially when she panned over to the raccoon in the lamp over the dinner table it looked like she had put it in a gibbet. And yeah, she could have handled that a lot better.

What a maroon.
Next time try opening the door, closing other interior doors, and keeping your dog from standing between the animal and the exit.
I bet she's not even with it enough to get her dog treated for possible rabies after it was bitten.

She should be grateful it didn't become a woodland critter Christmas, blood orgy and all.

About 20 years ago, I thought it would be cool to do this in real time with police radar. You get a radar signal off your detector, but it's coming from a lamp post, keep speeding. If it's coming from that bush a 1/2 mile down, beside the road, slow down.
