Abstract : Recent recordings of pressure waves caused by nuclear explosions were of good quality resulting from improvements in the microbarograph and greater amplification of the recordings. In 1961 to 1962 clear microbarograph recordings were taken mainly of several large-scale nuclear tests at Novaya Zemlya. It was possible to investigate in detail the propagation distances of pressure waves. On 30 October 1961 the waves from a 55 to 60 megaton (Mton) blast at Novaya Zemlya had dispersed on a global scale and were abundantly reported. Comparisons of theoretical characteristics of pressure waves (from the atmospheric models Oyamamoto, et al) with the measurements were made and analyzed with the help of even newer models. (Author)
