The Use of Geophysical Surveys in the Study of a Landslide-Prone Area near the Village of Dolan in the Almaty Region of Kazakhstan

In southern Kazakhstan, landslide control is highly relevant for settlements located in areas with mountainous terrain. This study was conducted to observe the results of applying electrical, seismic and magnetic surveys to investigate a landslide-prone slope in the Almaty Region. The aim was to improve the reliability of geophysical data when assessing the state of the landslide body. For the first time for this landslide, based on a joint analysis of geoelectric and velocity characteristics, the structural heterogeneities associated with unconsolidated and water-saturated soils, as well as fractures, were identified. The combination of data on the elastic, electrical and magnetic properties of the studied medium significantly improved the clarity of the interpretation of geophysical data when studying the landslide massif. This made it possible to refine the internal structure of the landslide and identify areas with an increased likelihood of deformation. The obtained results provide a reliable basis for assessing slope stability and demonstrate the need for integrated geophysical surveys to reduce the risk of landslides. Along with engineering–geological methods, geophysical surveys will be an integral component of monitoring landslide-prone areas, which will enable timely implementation of organizational measures to protect infrastructure facilities.
