The methodology used for an initial seismic zonation is briefly introduced and then developed to provide details of a microzonation presently in progress for the Costa Oriental del Lago Maracaibo coastal dyke protection system. The microzonation is focused towards the evaluation of dynamic site response of selected representative soil profiles. The results of the study are to be applied for evaluation of seismic stability and deformation mechanisms for the coastal dyke system with a view to defining remedial measures for critical sections of the linear earth structure
