[@aloysiusbelisarius9992]

That's official government jargon, and how they have sold that test publicly for the last 50+ years. They never released the actual yield measured, just citing "under 5 megatons" to somehow appease the Russians, though how that was supposed to serve any purpose is still beyond me. But independent seismic detectors estimated the shot to yield between 4.8 and 5.2 megatons. Unless there is a test that I have not yet been schooled on, this was *the* largest underground nuclear blast ever, *period.* Two years later, Russia tried doing something similar; but their experiment involved a daisy-chain of *three* bombs, which cumulatively (for those in Rio Linda, that means added up together) yielded only 4.4 megatons. I know, I know, there's nothing "only" about 4.4 megatons underground, but that still made their test weaker. Funny, coming from the country that detonated the three (maybe four) largest-ever nuclear bombs.

[@aloysiusbelisarius9992]

@@MaryStewart Indeed. It was tricky enough detonating something a tenth of that yield on an island situated right on a very active fault line.

There were 3 underground nuclear tests on Amchitka Island. Long Shot, Milrow, and Cannikin. I worked out there for 3 years; cleaning-up WW2 debris and building a “relocatable, over-the-horizon, backscatter radar station,” for the Navy...in the early ’80’s. One end of the Island had the “transmitter,” and the other end had the “receiver.” One side-note: Before we went out there, we were told that there was NO “tritium” in the water supply...because it was well-water. After our 3 year hitch, the Department Of Energy told us...by the way, there IS “tritium” in your water supply!!! The Government LIED to us, just so that Ronald Reagan could have one of his “Star Wars” projects fulfilled!!! Now, all of us who worked on Amchitka are in a D.O.E. database...to see who dies from cancer! It’s sad to think that our own government treats us like a “renewable, natural resource,” just as long as they get what they want. I do have plenty of fond memories: Scouring every inch of the Island on a Honda Four Trax 4x4, catching Dolly Varden on every cast in Cannikin Lake, and recovering tons of Coke bottles left by the 20,000 G.I.’s who inhabited the Island during WW2.

Funny, that device and instrumentation pack looked exactly like a *Sprint* missile, the other missile intended for the Safeguard facility, despite the warhead being intended for the larger Spartan. That test was originally meant to be done in 1968 or '69 in Nevada, but not at the designated Nevada Proving Grounds. By then they knew the testing already conducted there was shaking up buildings in Vegas. They searched for a more isolated area that would be far enough away from Vegas to avoid public outcry from a test that big. They picked the Hot Creek Valley in Central Nevada, near Tonopah. The "Crosstie-Faultless" test performed there in January of 1968, with a proven 1-megaton device, was meant to test the integrity of the land, see if it could withstand the ultimate larger test. That test was considered a failure because of the large degree of faulting that resulted in the area around the test (irony, considering the test's code name). It was decided that the land was unfit for multi-megaton nuclear tests, so a similar calibration test was conducted at Amchitka Island in the fall of 1969 during Operation Mandrel (the "Milrow" test).

[@petergray2712]

The Spartan missile was an anti ballistic missile meant to intercept incoming Soviet ICBMs. Naturally it had a 5 mt nuclear warhead, because the only way to defend the CONUS against enemy nuclear warheads was to detonate another large nuclear warhead directly overhead. Fortunately the ABM Treaty was signed in 1972 and put a stop to this madness.

F = 1/2*m*v^2 10^16J = 1/2*10^22kg*v^2 v^2 = sqrt(2*10^16J/10^22kg) v = 0.0014m/s This explosion could at best have accelerated the plate to 0.0014m/s assuming a pointlike collosion and perfect conversion (you can assume a loss of around 3 orders of magnitude combined).

Legit earthquake? This 5mt device caused a 6.8 quake?

When a hole that deep is made, like a very deep mine, I always thought that instead of being freezing cold, it actually became hot from geothermal energy and natural radiation in the rock. The men who went down that hole were very tough and brave.

[@Ou81gi812]

Everyone who went down that hole is on a Dept. Of Energy “watchlist,” because they were exposed to radiation. In fact, everyone who has ever worked on Amchitka is on that list...including me.

Detonating a nuclear weapon that close to one of the most dangerous subduction zones, what could go wrong???

[@trebreh1100]

To bad the native people that lived here before we did weren't as smart as us. They just lived at peace with and respect of the earth. But we can "control" our destruction and defilement of our planet and leave the mess for future generations to deal with.

Apparently earthquakes can make the ground throughout the landscape heave up and down in a wave or waves. Some people in Japan and California have actually seen it during strong earthquakes. It makes me wonder whether earthquake waves going through the ground/landscape look like the ground/landscape heaving up and down in a wave between 2:42 and 2:50?

[@JustSomePerson8]

A little bit different but the ground becomes loose and basically becomes liquid. Watch land slide videos and your see how the ground moves/acts

The next generation of thermonuclear weaponry will be based on carbon fusion as opposed to hydrogen fusion. The reason being is that as fuel for a fusion reaction, hydrogen is relatively benign, compared to carbon. Hydrogen (and its isotopes) deflagrate, whereas carbon detonates. Ask any astrophysicist about Type 1 supernovae.......

So how much wildlife was killed.

Did you not watch the video?

If radiation didn’t escape, what explains the light, the camera saw clearly

[@USAmerican100]

All that expense and destruction for a nuke that was never deployed operationally.
