Аnnotation: The relationship between strong magnetic storms caused by class X solar flares that occurred in solar cycles 23rd and 24th and seismicity variations (seismic noise) is considered. We use data on the time dependences of seismic noise parameters (root mean square deviation, RMS) recorded by stations of the KNET seismic network when monitoring the seismicity of the territory of the Bishkek geodynamic proving ground (Northern Tien Shan). Signs of the influence of a magnetic storm that occurred after strong solar flares on the seismic process are noted. It is shown that a short-term in-crease in seismic noise RMS during a magnetic storm (September 7–8) caused by a super-strong solar flare on September 6, 2017 is associated with an earthquake (M = 8.1) that occurred on the southern coast of Mexico on September 8, 2017.
