## 5 Conclusions  
Seismic zonation alone is not necessarily sufficient, as there may be variations inherent to local conditions that are not fully captured by general regulations. The procedure proposed in this study, while a valuable tool, requires additional analysis of the local response in singular zones to achieve a more precise seismic characterization. Regional modeling, combined with seismic zonation, provides a first approach to identifying these areas that may require more detailed exploration or the implementation of more specific local response analyses. The microzonation campaign employed both nationally and internationally recognized techniques. However, the innovative aspect of this study lies in the integration of a three-dimensional finite element model (3D FEM) to simulate the dynamic behavior of the terrain. This approach enables a more granular identification of localized seismic effects that might otherwise go unnoticed, offering a refined methodology for assessing site-specific risks in regions with complex geology. It is crucial to consider the practical implications of these results in the context of future constructions and the review of local regulations. The identification of areas with singular seismic responses allows for adjustments to be proposed in current building codes, which could include recommendations for reinforcing buildings or limiting development in particularly vulnerable areas. Similarly, these results contribute to expanding the database of microzonation studies conducted on dune soils, which are present in countries with diverse seismic characteristics such as India and the western United States. This allows for the comparison of characteristics and the assessment of the influence of climate changes on the properties of dune soils, which may affect dynamic response. The results obtained in this study provide insight into how microzonation and seismic response analysis could influence urban planning and structural design in a city. In the case of the urban sector of Concon, the response spectra identified in different areas of the city reveal variations which, although not highly significant, could have direct implications for structural safety. Additionally, the results of this study may serve as a basis for correlatingpotential future damage to new and existing structures resulting from a strong earthquake affecting the locality. Finally, regarding community resilience, the seismic microzonation study presents the following challenges:  
* Highlighting the need for public education programs and professional training in the interpretation and application of microzonation maps to ensure that risks are adequately integrated into planning and construction. * Concluding on how the integration of seismic microzonation into urban planning and disaster risk management can significantly improve safety and resilience in seismically active areas. This is particularly relevant, as highlighted in recent studies that emphasize the role of resilience in geotechnical engineering and urban infrastructure [54].
