The seismic classification in Emilia-Romagna

In order to reduce the effects of an earthquake, the State has concentrated its action on territorial classification, based on past earthquakes' intensity and frequency, and on the application of special regulations of buildings in areas classified as seismic.

The seismic action is defined for each site by the seismic hazard parameters set by the technical standards for construction NTC 2018.

The seismic classification constitutes a technical-administrative reference for managing the control of projects and the priority of actions and measures for the prevention and mitigation of seismic risk.
