Seismic P waves from a total of about 200 nuclear explosions in the USA, the former USSR and China, observed at 10 arrays and four networks in Europe, Canada and the USA, are used to analyse the structure at the base of the mantle and the core-mantle boundary (CMB). The simple waveforms and well-con...
