Amplification of seismic ground motion in the Tunis basin: Numerical BEM simulations vs experimental evidences

► Seismic wave amplification in the Tunis basin is strong. ► The Boundary Element Method quantifies the parameter sensitivity of the amplification process. ► Maximum amplification level and related frequencies well retrieved by BEM simulations. ► Overall maximum amplification has to be considered to avoid the sensitivity of the location of maximum amplification in space. ► Influence of the wave-field incidence and material damping is also shown.
