Permanent ground displacement across earthquake faults, landslides and natural slopes

Abstract

Permanent ground displacement analysis methods, as very important aspect of the seismic dynamic analysis is explained in the paper. A methodology for probabilistic hazard assessment of permanent displacement across natural slopes and landslides caused by earthquake rupture is presented, compatible with regions with low to moderate seismicity, as well as comparison with the results of the other authors. The results show that for the most cases, in terms of displacement of earthquake faults the displacement hazard is small, in contrast to ground shaking hazard. From the other side, slope displacements (rockfalls landslides, mudflows) as side effects may cause huge consequences during the earthquake.
