A PeaceWorks-KC Board member tripped upon an Open Culture cache of videos of nuclear explosions from 1945 to 2015, including test explosions and the Hiroshima/Nagasaki attacks. Here’s the link to the Open Culture article by Colin Marshall (https://www.openculture.com/2021/09/see-every-nuclear-explosion-in-history-2153-blasts-from-1945-2015.html) and links to videos with related content.
The Open Culture article begins thus:

“There have been more than 2,000 nuclear explosions in all of history — which, in the case of the technology required to detonate a nuclear explosion, goes back only 76 years. It all began … on July 16, 1945, with the nuclear device code-named Trinity. The fruit of the labors of the Manhattan Project, its explosion famously brought to the mind of theoretical physicist Robert J. Oppenheimer a passage from the Bhagavad Gita: “Now I am become Death, destroyer of worlds.” But however revelatory a spectacle Trinity provided, it turned out merely to be the overture of the nuclear age. … Little Boy and Fat Man, the bombs dropped on Japan in World War II … remain the only detonations of nuclear weapons in combat, and thus the nuclear explosions everyone knows, but they, too, represent only the beginning.”
