Underground Nuclear Explosion - Project Sedan Nevada 1962

@fooootie Most if not all bombs in the US stockpile are thermonuclear, even though they're not megaton strength. It's the easiest way to implement a lot of useful features.

there doing shit like this in the middle of nowhere and they are complaining about overpopulation.

This was a realatively puny thermonuclear ( i.e., H-Bomb) blast.

104 kilotons is 104,000 tons of TNT,

or about 5 times the power of the Nagasaki bomb.

Most H-bombs are in megatons of TNT - or millions of tons.

Only one megaton therefor would be ten times more powerful than this.

The largest bomb ever detonated was 50 megatons.

Also, notice the speed at which the material is ejected here.

were did this happen and why?

[Nuker1337]

The answers to those questions are found right in the title you ignoramus. The project evaluated the use of nuclear explosives to excavate large craters.

[leeraconteur]

For a time there was extensive research into using buried nukes for cratering - enlarging the Panama Canal, for instance; and for defusing earthquake faultlines.

Actually only part of this video shows Project Sedan, the other tests in this video include: Shot Bilby 1963 249 KT at 0:25, Project Gnome 1961 3.5 KT at 0:35-0:45, Shot Kilickitat 1964 70 KT at 0:43, and the damage at hot creek valley following Project Faultless 995 KT in 1968.
