Sidorin] Sharp changes in the character of the Rayleigh-Schuster hodograph in the vicinity of equinox moments have been detected as a result of an investigation into the seasonal variations in the diurnal periodicity of weak earthquakes of the Garm research area. The average annual hodograph of the diurnal periodicity of earthquakes is clearly divided by equinox moments into individual pieces with different slopes. This effect also manifests itself in the plot of changes in the hodograph vector length. The identified pieces differ in the amplitude and acrophase of the diurnal seismicity trend.
