Mapping of changes in the stress-strain state of a landslide risk slope using an Earth's natural pulsed electromagnetic field method

Among the wide range of hazardous natural processes and phenomena, the exogenic geodynamical processes stand aside. These events can either directly or indirectly provoke or amplify socio-economic or technogenic risks, and differ considerably in the time and space scales. The landslide processes can affect the environmental situation, decrease the durability of real estate objects, compromise the integrity of transportation and engineering infrastructure, and endanger the population safety. Among the reasons of soil plots destabilization are water cuts and technogenic stress on the geo-environment. As cities continue to grow, the environmental load increases. Global warming leads to an increase in precipitation and changes the regional hydrogeological conditions. Therefore, the problem of landslide research and forecasting becomes more urgent. This work presents results of a field research carried out on a site prone to intensive landslide process development, ravine erosion, and rain-wash by using an Earth's natural pulsed electromagnetic field (ENPEMF) method. It has been demonstrated that the exogenic slope processes can develop rapidly and the occasional surveys alone are not enough to protect the infrastructure objects. It is necessary to establish an online ongoing monitoring of the stress-strain state (SSS) of the rocks. The ENPEMF method allows an instrumental real-time estimation of the soil stability and can be recommended for continuous monitoring of the SSS of the rocks.
