Seismically induced landslide displacements: a predictive model
Engineering Geology, 2000Newmark's model for predicting earthquake-induced landslide displacements provides a simple way to predict the coseismic displacements affecting a sliding mass subject to earthquake loading. In this model, seismic slope stability is measured in terms of critical acceleration, which depends on the mechanical soil properties, pore-pressure distribution ...

Seismic Noise Azimuthal Spectral Ratios to Monitor Landslide Kinematics
NSG2021 27th European Meeting of Environmental and Engineering Geophysics, 2021Summary In this work, we explore the potential of seismic noise as a monitoring tool for landslide kinematic behavior. We monitored an earth slide with low-frequency seismometers and we collected ambient vibrations during two following stages characterized by different displacement rates and stress states of the involved media.

Seismic Characterization of Landslides and the Emergence of Seismic Monitoring
Proceedings, 2012After a short introduction on the main problems that need to be better understood in order to better model landslide dynamics, this contribution focuses on how geophysical methods and in particular seismic methods can help in better characterizing the geometry and heterogeneities of landslides.

Multivariate Fragility Functions for Seismic Landslide Hazard Assessment
Journal of earthquake engineering, 2018This paper represents multivariate fragility functions (MFFs) based on sliding displacement of soil slopes for landslide hazard assessment. The MFFs correlate the sliding displacement probability of slopes to earthquake intensity measures (IMs ...

Permanent seismic deformation analysis of a landslide
Landslides, 2005A failed slope may not necessarily require a remedial treatment if it can be shown with confidence that the maximum movement of the slide mass will be within tolerable limits, i.e., not cause loss of life or property. A permanent displacement analysis of a landslide for static and seismic conditions is presented using a continuum mechanics approach ...

Seismic Data Analytics for Estimating Seismic Landslide Hazard Using Artificial Accelerograms
2021Accelerograms record energy released by earthquakes as accelerations. Earthquakes and their repercussions such as tsunami and landslides are a huge threat to human life. Earthquake-induced landslides are voluminous and rapid by nature. To critically evaluate the possibility of landslides due to earthquakes, accelerograms recorded at the landslide site ...
