The Mangyshlak peaceful nuclear explosion (PNE) sequence consisted of three detonations in western Kazakhstan in 1969 and 1970. Although ground‐truth (GT) locations for PNEs conducted in the former Soviet Union are generally thought to be well known, they can be erroneous by up to tens of kilometers, and the Mangyshlak sequence is no exception. We identified collapse craters for the first two events using Google Earth satellite imagery. A candidate location for the third event was determined using a cluster analysis location routine for the relative location with respect to the known collapse craters. All three locations were confirmed as GT‐0 locations by site visits. Relative to previously published and accepted coordinates for the three Mangyshlak PNEs, our locations differ by 2.3, 6.7, and 15.7 km, respectively.
