The results of instrumental observations of the electromagnetic effects of a strong earthquake and its aftershocks that occurred on January 22, 2024 (Northwestern China) with a magnitude in the range of 4.9–6.9 and a weaker one the same year with a magnitude in the range of 5.4 (Northern Kyrgyzstan) are presented. Observations were carried out at two magnetotelluric monitoring points located in the Chu basin (Aksu 42.60911°N, 74.00833°E; Chon-Kurchak 42.62828°N, 74.60671°E in Northern Tien Shan) on the territory of the Bishkek geodynamic proving ground (BGPG). It is shown that an earthquake with numerous aftershocks located at distances of ~450 km from the recording points is reflected in all recorded parameters, while a weaker earthquake, but located closer, does not manifest itself in one of the horizontal components of the electromagnetic field. The characteristic periods of electromagnetic signals caused by earthquakes are given, and their amplitudes are estimated.
