Abstract Seismic microzonation represents a basic tool for local administrations in the developing of cost-effective risk reduction strategies and emergency planning. In recent years, the Italian scientific community has been deeply involved in implementing best-practices and tools to make seismic microzonation studies affordable by allowing its widespread application. Specific guidelines were provided that are representative of the international state of the art in this field. Moreover, the national Center for Seismic Microzonation and its applications (CentroMS) was established, which includes the most important Italian scientific institutions involved in seismic microzonation studies during last years. One of the purposes of this Center is supporting local Authorities and professionals in the field practice. Effectiveness of this organization has been tested during most recent seismic sequences, where the Center was charged to support the development of reconstruction plans. In this review paper the main features of these activities are addressed by focusing on experiences gained in the seismic microzonation studies carried out at 138 Municipalities in the area of Central Italy damaged by the 2016–2017 seismic sequence.

1 Introduction The dramatic experience after the 2016-2017 seismic sequence in Central Italy puts in evidence, once more, at what extent the Italian territory is exposed to the effects of medium energy earthquakes which, due to the high vulnerability of exposed goods, are responsible for tens of casualties and damages for billions of Euros. In this situation, developing effective prevention activities is mandatory for the whole Italy. Due to the extension of earthquake prone areas and the density of population, these efforts must be graduated in order to be economically and politically sustainable. To this purpose, seismic risk maps represent a basic tool to prioritize interventions. The first
