Another fun fact, the priority for detecting nuclear testing led to seisometers all over the planet. So the detection the exact position and nature of any disturbance on the planet became radically better. This was quite the boon to anyone interested in earthquakes, not only can the earth quake be detected in 2D, but accurately in 3D. The number and accuracy is enough you can see where on each fault is, the thickness of the crust, and the outline of subduction zones in 3d. Pretty crazy to see enough detail to see where plates enter the mantle and melts.
Said sensors can also track sonic booms from secret supersonic planes, but governments don't like to talk about that.
