The purpose of Seismic Microzonation studies is to identify the local conditions that can significantly modify the characteristics of expected seismic motion or cause major permanent deformations on buildings, structures and infrastructures. The results of studies are useful to plan and to realize actions for seismic prevention and risk assessment.
Application areas of Seismic Microzonation are described in “Guidelines for Seismic Microzonation” and can be summarized below:
- territorial and urban planning: they integrate the knowledge of those components that give rise to seismic risk and provide decision-making criteria related to the prevention and mitigation of this risk both at area – wide and municipal scale (for further details see Chapter 1.7 of Guidelines for Seismic Microzonation);
- emergency planning: at both the municipal and provincial level, SM studies may help identify the strategic elements of an emergency plan and, in general, of civil protection resources (for further details see Chapter 1.8 of Guidelines for Seismic Microzonation);
- design of buildings or structures: (both existing and in project) SM studies highlight possible phenomena of motion amplification induced by local lithostratigraphic and morphological conditions, as well as instability and permanent deformations caused by earthquakes (for further details see Chapter 1.9 of Guidelines for Seismic Microzonation).
