Effective geophysical methodology for investigation of a complex landslide system in Valjevo, Serbia
MetadataShow full item record
Torrential rainfall occurred at the end of May 2014 across Serbia, and Bosnia and Herzegovina (BiH) triggered thousands of new landslides. Shortly after a diverse group of geoscientists united to investigate this phenomenon. The methodology used to study and characterize landslides consisted of a combination of highresolution seismic profiling, resistivity measurements, refraction tomography and MASW, all conducted along the same track. All body wave related investigations were extracted from a high-resolution, high-density seismic reflection survey. This approach enabled us to study many different landslides in a short period of time. Joint analysis of seismic and electric measurements allowed us to characterize important structures, local discontinuities, geometry of the near surface layers and architecture of a landslide. Reactivation potential was studies through time lapse geophysical measurements that proved to be difficult to accomplish with satisfactory repeatability in populated areas.
