We are writing reviews of the nuclear testing activities of the Former Soviet Union at that nation’s two major nuclear weapons test sites: Novaya Zemlya (Russia), and Semipalatinsk (Kazakhstan).
This project is using the seismic magnitudes and announced yields for some underground tests, to calibrate the relationship between seismic signal strength and yield: and then applies that calibration to derive yield estimates for nuclear tests whose seismic magnitude is known but whose yield has not been announced. We are also obtaining highly accurate estimates of the location of hundreds of nuclear tests, in the period from 1961 to 1992.
