Seismic slope stability is one of the critical areas in the field of earthquake geotechnical engineering in view of catastrophic geohazards. Over the years, significant advances have been made in the methodologies of slope stability analysis subjected to seismic loadings. The seismic stability analysis of the slopes is influenced by various factors, and therefore, a complete seismic slope stability analysis must account the soil properties, geological parameters, slope geometry and loading to eliminate the susceptibility of slope failures. A detailed review of the literature shows that several analytical and numerical studies have been carried out to investigate the effect of different geotechnical parameters on stability analysis during earthquake condition; however, the effect of vertical seismic loading on the slope stability has generally be ignored. It is also noticed that most analytical methods of seismic slope stability analysis, as available for routine field applications, account for the horizontal seismic loading only. Recent findings have shown that consideration of vertical seismic force has a high possibility to influence the conventional slope stability analysis. Therefore, there is a big scope to study the combined effect of horizontal and vertical seismic loadings on the stability of slopes by developing improved analytical methods and numerical models...
