Pace, D. Albarello, P. Boncio, M. Dolce, P. Galli, P. Messina, L. Peruzza, F. Sabetta, T. Sanò, F. Visini] After the April 6th 2009 L'Aquila earthquake (M w 6.3), where 306 people died and a further 60,000 were displaced, seismic microzoning investigations have been carried out for towns affected by a macroseismic intensity equal to or greater than 7 MCS. Based upon seismotectonic data, historical seismicity and strong motion records, we defined input spectra to be used in the numerical simulations of seismic microzoning in four key municipalities, including the town of L'Aquila. We adopted two main approaches: uniform hazard response spectra are obtained by a probabilistic seismic hazard assessment introducing some time-dependency for individual faults on the study area; a deterministic design spectrum is computed from magnitude/distance pairs extracted by a stationary probabilistic analysis of historical intensities. The uniform hazard spectrum of the present Italian building code represents the third, less restrictive, response spectrum to be used for the numerical simulations in seismic microzoning. Strong motions recordings of the main shock of the L'Aquila sequence enlighten the critical role played by both the local response and distances metric for sites located above a seismogenic fault; however, these time-histories are compatible with the uncertainties of a deterministic utilization of ground motion predictive equations. As recordings at very near field are rare, they cannot be neglected while defining the seismic input. Disaggregation on the non-Possonian seismotectonic analysis and on the stationary site-intensity estimates reach very similar results in magnitude-distance pairs identification; we interpret this convergence as a validation of the geology-based model by historical observations.
