The article presents the results of a study of seismic activity in the Gorlovskaya Depression (Novosibirsk Region) using the electrical resistivity tomography method, where since 2017 there has been an increase in the number of earthquakes with magnitudes up to 𝑀 = 4.7 associated with intensive open-pit coal mining. The purpose of the study is to determine the criteria for the manifestation of natural and natural-technogenic hazardous processes based on the analysis of data from one of the ground-based electrical exploration methods – electrical resistivity tomography. From the analysis of electrical resistivity tomography data obtained as a result of regular observations in 2023-2024, significant variations in the electrical resistivity in fault zones after seismic events were revealed, the azimuthal dependence of electrical resistivity variations on the direction to the earthquake epicenter was established. To quantitatively assess the difference sections, the parameter 𝐷𝑟 was calculated, showing the dependence on magnitude and epicentral distance.
