Simplified techniques based on in situ testing methods are commonly used to assess seismic liquefaction potential. Many of these simplified methods are based on finding the liquefaction boundary. As the liquefaction classification problem is highly nonlinear in nature, it is difficult to develop a comprehensive model taking into account all the independent variables, such as the seismic and soi...

The study area is located in one of the most earthquake prone regions southern Ethiopia, which characterized by small-to-intermediate occurrences causing damage to buildings. Predicting liquefaction hazard potential and local site effects are imperative manage reduce buildings loss lives. objectives this work were perform equivalent linear response analysis (ELA) shear wave velocity (Vs.)-based...

iran is an active seismic region. earthquake damage is commonly controlled by three interacting factors including source and path characteristics, local geological and geotechnical conditions and type of the structures. obviously, all of this would require analysis and presentation of a large amount of geological, seismological and geotechnical data. in this paper, nonlinear geotechnical seismi...

The İzmit Basin has developed under the control of North Anatolian Fault Zone (NAFZ). The basin is morphologically located in a plain between the Kocaeli Peneplane in the north and the Samanlıdağ Highlands in the south. NAFZ covering the study area in east west direction affects the region. Layers of sand and silty sand deposits are widespread in the alluvial basin. The groundwater level is con...

Soil liquefaction is the phenomenon of temporary loss of shear of saturated cohesionless soil under the influence of vibrations caused by earthquakes. The extensive loss of lives and civil infrastructure system like buildings, bridges, highways etc. caused by liquefaction emphasize the need for strong and reliable methods for evaluating the liquefaction potential of sites. Simplified techniques...

Lateral spreading is one of the most destructive effects of liquefaction. Liquefaction is known as one of the major causes of ground failure related to earthquake. This phenomenon is likely to occur when the rate of earthquake-induced excess pore water pressure buildup exceeds the rate of drainage. Estimation of the hazard of lateral spreading requires characterization of subsurface conditions....
