A significant event took place on June 18, 2023, in Tomsk, Russia, involving a powerful occurrence of the Schumann resonance. The observatory in Tomsk, renowned worldwide for its measurement and recording of the Schumann resonances, detected an unprecedentedly strong signal. The recorded amplitude reached an astonishing 190, surpassing the usual range of 7.8 to 8 Hertz, and it appeared on the spectrograph at 40 Hertz. This anomalous spike was highly unusual and had not been observed previously.
