Acknowledgements. This work was developed in the framework of the ReLUIS-DPC 2010-2013 Research Project promoted by the Laboratories University Network of seismic engineering (ReLUIS) and founded by the Italian Civil Protection Department - Presidency of the Council of Ministers (DPC). The authors wish to thank the staff of Seismic Monitoring Service of the Territory of the Seismic and Volcanic Risks Office of the Civil Protection Department, that that provided us waveforms and associated information used in this work.

Naso 3 1 CNR-IGAG 2 Dipartimento di Ingegneria Civile e Ingegneria Informatica, Università degli studi “Tor Vergata”, Roma 3 Dipartimento della Protezione Civile, Roma A seguito all’emanazione della legge 77/ 2009 è stato avviato il programma di finanziamento per le Regioni al fine di realizzare studi di Microzonazione Sismica (MS) nei Comuni la cui PGA è maggiore o uguale a 0,125 g. Il riferimento metodologico adottato da tutte le Regioni è costituito dagli ICMS2008 e dagli “Standard di rappresentazione e archiviazione informatica” (versione 2.0, maggio 2012), appositamente predisposti dalla Commissione tecnica di supporto e monitoraggio per gli studi di MS istituita con OPCM 3907/2010. Già nell’ambito delle prime sperimentazioni effettuate a seguito del terremoto dell’Aquila del 6 aprile 2009 era emerso che l’applicazione degli ICMS2008 non forniva indicazioni per 317 GNGTS 2013 S essione 2.2
