Assessment of Landslide by Its Fracture System using Electric Resistivity Tomography and Pressure Probe Method | Chapter 4 | Current Advances in Geography, Environment and Earth Sciences Vol. 4

 The goal of this chapter was to investigate a slow-moving loess landslide in South Hungary. Unlike earlier efforts, we were able to pinpoint its fracture system. It appears to be the only option to learn about the landslide's structure and subsequent evolution due to the uniform nature of the loess. In addition to the well-known Electrical Resistivity Tomography, the Pressure Probe (PreP) method was utilised to analyse the apparently thick fracture structure (ERT). This approach was developed to discover and analyse mechanically weak zones that are not visible on the surface, such as those caused by landslides. The ERT has been very successful in locating fracture zones. allowing for the prediction of future rupture surfaces and, as a result, the designation of dangerous zones Both methodologies were successful in determining the location of a landslide's fracture system. The mass shifts that occurred around a year and a half after the observations supported geophysical predictions. For giving early danger alarms and averting damage to structures or compromising human life, the employment of the ERT and PreP techniques is strongly advised.
