“…It is generally recognized that the area associated with the strongest ground motion and most significant damage during an earthquake has an elliptic shape, presumably, affine to an elliptic model of earthquake source (e.g. see Al Shawa et al, 2021; Weixiao, Weisong, & Dehu, 2021). In reality, the analyses of macroseismic effect (Molchan, Kronrod, & Panza, 1997) and the InSAR images permit recognizing different patterns of seismic effect propagation (Petricca, Bignami, & Doglioni, 2021): elliptical for dip‐slip or four‐lobe for strike‐slip fault earthquakes.…”

The Neo Deterministic Seismic Hazard Assessment (NDSHA) is the innovative multi‐disciplinary scenario‐physics‐based approach for the evaluation of seismic hazard and risks. When an earthquake occurs, the ground shaking does not depend on its likelihood according to the widespread Probabilistic Seismic Hazard Analysis (PSHA), which estimates are too often wrong. An “unlikely” earthquake can occur at any time and, sooner or later, with 100% probability. Therefore, from a perspective of safety, it is essential that infrastructure and public installations are designed so as to resist future strong earthquakes. NDSHA has proven to both reliably and realistically simulate comprehensive sets of hazardous ground motions in many regions worldwide. Today NDSHA is gaining momentum in spreading worldwide an innovative Paradigm of Reliable Seismic Hazard Assessment (RSHA) that should ultimately change mind‐sets of scientific and engineering communities from disbelief in probabilistic forecasting to optimistic challenging issues of neo‐deterministic predictability of Natural Hazards and Risks.

“…Various geostatistical methods are actively used to solve similar problems, in particular for modeling the spatial distribution of environmental data [26] and assessing the homogeneity of data [27]. These works, along with numerous other materials [28,29] containing examples of spatial modeling in geology, ecology, geophysics, etc., are a good basis for conducting this study. Nonetheless, they do not contain a solution to the main problem associated with modeling the data of measurements of the ENPEMF, which acts as a marker of active tectonic faults.…”

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.
