Global nature of the seismogravitational oscillations of the Earth

Direct experimental evidence for the global nature of the seismogravitational vibrations of the Earth within the range of 0.03–0.1 mHz is obtained on the basis of the analysis of synchronous observations with the help of vertical seismographs in Eurasia and North Africa. A number of stable, statistically significant vibrations are discovered. Analysis of 66 observations at ten stations showed that stable global vibrations exist in five frequency bands (45–51, 54–58, 61–65, 67–69, and 81–83 μHz).
