Forecast of violation of soil stability according to the parameters of pulsed electromagnetic fields of the VLF range

Abstract

The relevance of the task of monitoring and forecasting exogenous processes is determined by the widespread occurrence of landslides, including in many territories of the Russian Federation. Catastrophic slope failure is one of the most common natural hazards, resulting in both human casualties and economic damage. The aim of the study is to test the algorithms for assessing the stress-strain state of rocks using the parameters of the natural pulsed electromagnetic field of the Earth (ENEMF) on an active landslide that threatens the infrastructure of Tomsk. The paper shows that the precursors of the activation of geodynamic slope processes are fixed long before changes in the relief caused by the failure of rock blocks. The conducted studies have shown the high promise of the ENPEMF method for forecasting extreme events that pose challenges for the territory.
