滑坡灾害是一种复杂的地质事件，具有很高的社会经济影响，造成生命和财产损失。滑坡研究涉及多学科方法的应用。各种技术，包括表面和地下的方法已被应用于调查和了解其发生的机制。地球物理工具的应用就是这种先进技术之一。电阻率层析成像（ERT）技术是一种非侵入性的研究方法，本文对其应用的最新趋势进行了研究。ERT技术已广泛应用于从落石到泥石流的各种滑坡。该方法已被应用于各种地质条件和环境，识别滑动面，水文条件，重建的坡体，滑动材料的体积/厚度估计，并描绘内部结构。文中还讨论了测量中所使用的各种基阵沿着地形反演的算法。讨论了近年来使用的2D、3D和4D ERT技术的结果。展望了未来的发展前景和局限性。
Landslide disasters are known to be complex geological event with high socioeconomic effects in terms of loss of lives and properties. Landslide study involves the application of a multidisciplinary approach. Various techniques involving both surface and subsurface methods have been applied to investigate and understand the mechanism of its occurrence. Application of geophysical tools is one of such advanced techniques. In this paper, the recent trend in application of Electrical Resistivity Tomography (ERT) technique is being studied as it is a noninvasive method for investigation. ERT technique has been used widely for various landslides from rockfall to debris flow. The method has been applied to various geological conditions and environment to identify the slip surface, hydrological conditions, reconstruction of the slope body, estimation of the sliding materials volume/thickness, and depict the internal structures. Various array used in the measurement along with the algorithms for topographic inversion are also discussed. The results of 2D, 3D and 4D ERT techniques used in the recent times have been discussed. Future prospects and the limitations are also discussed.
