Characteristics of Surface Ground Motion in Beirut, Lebanon, from 3D Seismic Wave Simulation Open
Site effects arising from complex two- and three-dimensional (2D/3D) site geometries and highly heterogeneous soils cannot be fully captured by traditional one-dimensional (1D) ground response analyses. At geotechnical and sedimentary scal…

Ground motion simulation in Beirut from a large earthquake on the Mount Lebanon Thrust fault Open
Ground motion simulation is crucial for seismic risk assessment in cities with limited recorded strong ground motion data. Lebanon is located along the Dead Sea Transform fault system, which previously generated large earthquakes, but has …

A Comprehensive Analysis of Seismic Site Effects in the Grenoble Basin (French Alps) Open
The Grenoble basin, located in the French Alps, is a region of significant interest for seismic hazard assessment due to its thick sedimentary layers and surrounding high massifs, leading to 2D/3D complex wave propagation patterns. With th…

Using the soil subsidence from satellite Persistent Scatterer InSAR (PSI) to estimate site-effect parameters in high spatial resolution, case of the sedimentary basin of Grenoble (French Alps). Open
Following previous studies that identified a potential correlation of the subsidence rates of the soils with the sediment thicknesses (Hbed), or with the resonance periods of the soil columns (T0), we want to verify this correlation in the…

Estimating urban seismic damages and debris at the building-level: Application to the city of Beirut, Lebanon Open
The estimation of seismic damages and debris at the urban scale - at a precise building-by-building level- is challenging for several reasons. First, commonly used methodologies for seismic damage estimation rarely take into account the lo…
