Many LLNL Atmospheric Nuclear Test Videos Declassified

Peter Lobner

Lawrence Livermore National Laboratory (LLNL) has posted 64 declassified videos of nuclear weapons tests on YouTube. LLNL reports:

“The U.S. conducted 210 atmospheric nuclear tests between 1945 and 1962, with multiple cameras capturing each event at around 2,400 frames per second. But in the decades since, around 10,000 of these films sat idle, scattered across the country in high-security vaults. Not only were they gathering dust, the film material itself was slowly decomposing, bringing the data they contained to the brink of being lost forever.

For the past five years, Lawrence Livermore National Laboratory (LLNL) weapon physicist Greg Spriggs and a crack team of film experts, archivists and software developers have been on a mission to hunt down, scan, reanalyze and declassify these decomposing films. The goals are to preserve the films’ content before it’s lost forever, and provide better data to the post-testing-era scientists who use computer codes to help certify that the aging U.S. nuclear deterrent remains safe, secure and effective.”

Here’s a mesmerizing 14+ minute video created by Japanese artist Isao Hashimoto with a time-lapse map (single screenshot above) showing all of the nuclear explosions between 1945 and 1998, beginning with the “Trinity” test and concluding with Pakistan’s nuclear tests in  1998. Close your eyes for a moment and it sounds like you’re in a gambling casino near the digital slot machines.
