On an equipment complex of research institute NAO longitudinal seismic waves from some strong earthquakes (Kuril Islands, Pakistan, Indonesia, Molucca sea, Greece and so forth) were recorded through abnormal deviations of the time dependence of Fedchenko's clock. Decreasing of a dispersion of indications of Fedchenko's clock presumably caused by arrival of an infra low frequency electromagnetic radiation from the epicenter of an earthquake was observed some minutes before the seismic wave. Similar phenomena were registered by many researches at carrying out of explosive works.
