Project Cannikin Review by United States. Department of Energy. National Nuclear Security Administration.
This video reviews Project CANNIKIN, a nuclear test conducted on Amchitka Island, Alaska, at 11:00 a.m., Bering Standard Time, on November 6, 1971. CANNIKIN, a slightly less-than-five-megaton device, was the largest underground nuclear test conducted in the United States. CANNIKIN was conducted to proof test a warhead for the Spartan missile, a Safeguard Ballistic Missile Defense Program.
The video shows the nuclear device and instrumentation canister being lowered into the shaft, detonation sequences, and test effects. A long-range view of water turbulence after the detonation is shown, but no tsunami or large ocean wave was observed or recorded. Numerous ground shock waves are shown at normal speed and as seen by high-speed, slow-motion cameras located at various sites on the island. Surface effects at ground zero and other island locations were filmed one day after the test. Approximately 38 hours after the test, a subsidence crater, approximately 1.5 miles in diameter and 55 feet deep, began to form. Many scenes in the video have no sound intentionally; no material was deleted.
The three underground nuclear tests conducted on Amchitka Island, Alaska, were as follows:
• LONG SHOT, October 29, 1965, shaft, Vela Uniform Project, approximately 80 kilotons
• MILROW, October 2, 1969, shaft, weapons related, approximately 1 megaton (Mt)
• CANNIKIN, November 6, 1971, shaft, weapons related, less than 5 Mt

A decades gone uncle from Livermore CA worked at the big “laboratory” in town. I was just a kid when we visited in the late 60s and didn’t understand you weren’t supposed to ask him about his job, so I did. All he would say was- he was an electrician. I pictured him fixing the lights and fans. Maybe he was that kind of electrician, or maybe he worked on something else, but nobody knows.
Crazy that there's enough energy in that thing to basically move a mountain range 25 in.
No significant adverse effects were observed or recorded, no radiation leakage detected, no permanent harm to wildlife expected, it's all good boys and girls! - so there...so sad.
Nice video.
The Cannikin test was the watershed event that resulted directly in the formation of "Greenpeace". 5 Megatons is an enormous sized detonation.
Wow! didnt know that.
Now the new Neutron devices no explosions now contamination.
Only biological life killed and inna few hours Military can occupy city.
Samuel Cohen invented it in late 70s for US Military
The harbor was permanently lifted 4 to 6 feet!
At 7 minutes, are those two pulses of light coming from a small tube observing the detonation?
I was wondering if it was some kind of electrical discharge from the bomb..
They are some device that flashes at the same time the detonator is hit to show when the actual shot was initiated
Does anyone know how big the cavity is for cannikin ? It’s the largest underground nuclear explosion and there’s no actual measurement only theoretical calculations based on data .
My son was born in January 1970 & my 28th birthday fell just one day before the blast. I think perhaps to this point a good estimate of nuclear explosions totaling 2,300 since the day I was born, and I never knew of any of them. ""??"" hmmmmmm
¹Banished to lurking & looming underground tomb playground....
👍👀🌟🤯
Vastly better video quality:

Curious why in Alaska?
Why not in Nevada?
More isolated with zero population to disrupt test. Sterile test site.
I'm not certain, but I want to say they didn't do multi-megaton tests in Nevada...only on isolated islands
@@blurglide A lot of fault lines near there..
I am retired DOE /AEC.
It was too big... about 5 megatons. They did a one megaton underground detonation up near Tonopah, and it caused a rift to form in the valley floor above the detonation point that essentially caused the valley floor to drop about six feet along a fault line, so there was a 6 foot high escarpment cutting across the valley. They had been hoping to certify the area okay for tests up to five megatons (to perform the test done on Amchitka) but obviously if a one megaton detonation did so much damage, five megatons was completely out. SO they had to do it somewhere else, and the Aleutian Islands, being the middle of nowhere, was it. Watch this: ruclips.net/video/JufLGikdDWU/видео.html
The whole video is worth a watch, because there were a lot of nuclear tests done in various places around the USA besides the Nevada Test Site... but the time mark starts the video at the Faultless detonation in Tonopah and then directly covers the Cannikin detonation in Alaska. Later! OL J R :)
Darn, video not available? I’d like to see it
Algorithm.
That was a dumb thing to do
Why?
@@blurglide The tests were conducted near 2 fault lines in a volcanically active region.
