“…From the viewpoint of the fundamental theory, the waveform of the electromagnetic pulse generated by GDAFs, its frequency, period, and other parameters typical for the electromagnetic wave, are studied by various scientific schools, whose representatives are Mulev, S.N. [36], Frid, V. [37], Simpson, F. [38], and Sabaka, T. J. [39].…”

This paper examines the possibility of the spatial modelling of the Earth’s natural pulsed-electromagnetic-field measured values, which form a closed profile without the data inside. This geophysical method allows us to map active tectonic movement which breaches the integrity of pipes. During the experiment, 4.5 km of profiles were measured in the Admiralteysky district of St. Petersburg, Russia. Regular electromotive force (EMF) values and anomalous EMF values were obtained, ranging from 0 to 900 µV and above 900 µV, respectively. The anomalous values are associated with tectonic faults in the bedrock. The data obtained are characterized by complex spatial anisotropy associated with the development of two groups of tectonic faults of different orientations. The authors have considered the problems of the spatial modeling of the data obtained. The main problems, the solutions to which should allow the obtaining of adequate models, have been identified. Based on the analysis of the measurement results, geological features of the studied areas, as well as variography, the following possible solutions were proposed: changing the measurement technique; dividing the data array according to the main directions of anisotropy; the need to introduce additional correction coefficients. The problem revealed in this article requires further research on the basis of the obtained results, which will reduce the cost and timing of such studies, and, as a result, give an opportunity to take into account active tectonic disturbances during the construction and scheduled maintenance of underground utilities, which is especially important within the framework of the concept of sustainable development.

“…Small-amplitude movements along faults can result in discontinuity in residential engineering structures, accidents in heat distribution networks and water discharge systems, gas and oil pipelines, as well as in tunnels [7]. Currently, the issue of geodynamic activity at mining facilities and related accidents at mine workings is a subject of intensive study [8][9][10][11].…”

“…The background value depends on the properties of the surrounding space-the structure of rock mass, dynamoelectric phenomena occurring in rock mass, microseismic motion, manmade load, etc. Further, the ENPEMF is characterized by the presence of pulsed signals from remote sources, such as atmospherics and deep lithospheric processes [10,38]. Such pulsed signals are characterized by equal peak value of the signal at each point; therefore, they are not recorded during measurements, but increase the background value.…”

The paper presents an analysis of the method of recording the magnetic component of the Earth’s natural pulse electromagnetic field in an urban environment. This method of recording has already proved itself to be a method that allocates the stressed sections of rock mass at mining and, therefore, the authors consider it effective for allocating active tectonic disturbances and forecasting accidents at underground utilities, which will help reduce the potential environmental hazard of these objects.
