So you don’t buy that earthquakes can be man made? This is evidence from 60 years ago! It was detonated at least 6000 feet into the ground (roughly 2000 meters). This footage is from Project Cannikin, which was a proof-test for the 5 megaton warhead to be used on the Spartan missile system. Researchers were fearful of such a large device being detonated underground, so the testing was moved to way out in the middle of nowhere on the Amchitka penninsula in Alaska. The effect on the ground was necessary, and predicted, to see its pulse effect.
Cannikin (5 Megaton Nuclear Device Amchitka, Alaska). Excerpt from "Atomic Journeys: Welcome to Ground Zero". Mind you, the footage is directly above the epicenter, whereas the epicenter of most earthquakes (like the one in Japan) are like a mile or more below the ground and a few miles off-shore. (Don't quote me on that, though). I don't recall how deep this one was buried, but I think 1-2 miles is about right. (Don't quote me on that either!).
Seismic recordings of the test registered a magnitude of 6.8 on the richter scale as a direct result of the detonation. Over 1,000 after shocks with magnitudes as greater than 4.0 on the richter scale were recorded within the first 30 days following the blast.
The energy produced by the detonation caused the surface of the island directly above the device to rise 25 feet. Large portions of the coastline collapsed into the sea for a stretch of two-miles from ground-zero. The beach and ocean floor in the near vicinity, the Cannikin site were permanently raised 5 feet.
6.8 Magnitude Earthquake Generated By Underground Nuclear Explosion Cannikin Alaska
The blast caused a subsidence crater over a mile wide and 60 feet deep, which filled with water and became the largest lake on the island. Rockfalls, containing over 46,000 square yards of material, smothered intertidal marine life. Nearly three hundred deceased rock greenling fish were found offshore, and subsequent catches of rock sole declined substantially.
The remains of over 10,000 three-spined sticklebacks and 700 Dolly Varden were found in the island’s lakes, streams, and ponds. Perhaps 1,000 sea otters were killed, their skulls fractured by the force of the blast driving their eyeballs through the bones behind their sockets. Harlequin ducks were found with their backs broken and their legs driven into their bodies by the force of the explosion.
So you still believe there are no man-made earthquakes?
