What does a megaton look like?

If you're sitting on top of it when it happens, ear defenders will be the least of your worries.

Yes, you'd probably be most concerned about the potential nausaeating effects of weightlessness, how long it will be before the ISS comes around, and, of course, breathing...

Nevertheless, as a gentleman, one would retain one's composure.

Of course Old Bean! Stiff upper lip, what what?

Reminds me of that line from The Simpsons where Cecil Terwilliger (Sideshow Bob's brother, and played - of course - by David Hyde Pierce) - is about to blow up a dam, and Bob and Bart with it:

"And now to kill you. There may be a slight ringing in your ears. Fortunately, you'll be nowhere near them."

Just been reminded of a joke where a skydiver's parachute lines become hopelessly entangled so he jettisons it and pulls at his reserve only to have the release handle come off in his hand.
Just as he's starting to panic, he sees a guy in overalls floating up towards him so he shouts -
"HEY! DO YOU KNOW ANYTHING ABOUT PARACHUTES?"
And the guy in overalls shouts back -
"NO! DO YOU KNOW ANYTHING ABOUT GAS COOKERS?"

I blame computers. Before them, we just had kilometers. A million meters was just too far. 5km was a good run.

And that's one megaton. The Roosians tested the "Tsar" bomb, 57 megatons. 57 of those container ships stuffed with TNT.

So what would the effect be of detonating 57 of those container ships stuffed with Tsar bombs?

Here's a nice little toy, if you want to play nuke some more

Probably wipe France off the map. For example.

I tried the Tsar Bomba dropped on Liverpool. People in Manchester would be hit by flying debris the size of condominiums.

If you dropped it on Luxembourg, the whole country would be lava in one go.

Some Jap survived both WWII atomic bomb blasts and only died recently.

[Calilasseia]

Those were devices whose yield was of the order of 15 Kt, and were pure fission weapons. There wouldn't have been many survivors if the weapons had been megaton-yield thermonuclear ones.

"Japanese", dickhead.

Anyway, anybody who was in or near the cities and dies, from any cause, including being pecked to death by swans, gets added to the List of Casualties from the Bombs. Japan's way of milking the events.

It just shows what a fantastic leap we will make, when we start generating electricity with fusion.
A lot of tankers will be stood down, as well as delivery trucks to gas stations etc etc.

And the price and abundance will enable things we can't even dream of now.

[Clinton Huxley]

Aye, commercially viable fusion power would be great. Due in 2063 I hear.
