Landslides and Geophysical Investigations: Advantages and Limitations
Description
Geohazards are the most relevant processes that can damage or increase the risk of human beings, properties, critical and transport infrastructures, and environment itself. They also could involve the interruption of human activities. Among all the natural occurrences, landslides may be regarded as one of the most relevant damaging processes. Even though the catastrophic impact of landslides is not totally unavoidable, it can be significantly reduced increasing the capacity to assess and predict the risks and using different methods of mitigation. In the past years, many 2D and 3D numerical modelling methods have been designed and developed to assess slope stability, to predict response to triggers, to evaluate the slope deformation pattern evolution, and to perform back-analysis simulations. Nevertheless, such models still require access to detailed knowledge of the geological, mechanical, and hydrological properties of landslides and boundary conditions. Therefore, accurate geological field surveys have to be integrated by means of low-cost and noninvasive techniques, like the geophysical ones, to collect widespread data with the aim to reconstruct a suitable geological and hydrogeological model of the area, improving the reliability of deterministic model.
This special issue will be dedicated to landslides and geophysics and will make an effort to collect the current knowledge on recent developments and innovative applications of geophysical techniques (active and passive seismic, electrical methods, and microgravity) that contribute to understanding landslides phenomena. Moreover, contributions on the reliable constrictions of engineering-geological models and on the optimization of stability analysis outputs and stabilization plans by means of noninvasive techniques are mainly encouraged. Submissions on the advantages and limitations of mapping and characterizing landslides by means of low-cost techniques, like the geophysical approaches, are also solicited with special reference to different geomorphological context or in developing countries.
In this special issue, interested authors are encouraged to submit their unpublished contributions as original, state‐of-the‐art research, and review papers involving an in-depth and detailed examination of a representative subject of study.
Potential topics include but are not limited to the following:
- Benefits and drawbacks of mapping and characterizing landslides by means of low-cost techniques
- Electrical resistivity tomography and/or induced polarization tomography
- Active and passive seismic slope characterization
- Time-lapse and 4D landslides monitoring
- Self-potential landslides monitoring and rainfall interaction
- Slope modelling
- Rockfall seismic monitoring and modelling
- Constrictions of engineering-geological models
- Stability analysis
- Geophysical mapping and characterization of geological, geotechnical, and hydrogeological landslides parameters
