The heavy nuclear explosion on October 30, 1961, at 8.33.33 G.M.T. at a distance of 1160 km in Novaya Zemlya was recorded at Sodankyla by means of a seismograph. a microbarograph, a magnetograph. and a vertical incidence ionosonde. On October 31, the microbarograph again showed two very distinct and strong deflections, namely, at 18.32 and 21.28 G.M.T. These deflections are interpreted as being caused by round-the-world waves due to the same nuclear explosion, one being propagated in the baokward, the other in the forward direction. The mean velocity deduced from these round-the-world waves is 311 m/sec. lt is reasonably assumed that these waves are strong enough to cause a detectable ionospheric effect when passing over Sodankyla.
