Description

The probabilistic seismic hazard maps of the Italian national territory are represented by shaking parameters on a regular grid spaced by 0.05° and using two shaking parameters, PGA (horizontal peak ground acceleration) and Sa(spectral acceleration). Maps in peak ground acceleration (PGA) are evaluated for different probabilities of exceedance in 50 years (9 probabilities, from 2% to 81%). For each evaluation it is available the distribution of the 50th percentile (median map, which is the reference map for every probability of exceedance) and the distribution of the 16th and 84th percentiles, which give the variability of each estimate. Maps in spectral acceleration (Sa) are calculated for the same probabilities of exceedance in 50 years (9 probabilities, from 2% to 81%) and for different periods (10 periods, from 0.1 to 2 seconds). Also in this case for each evaluation is available the distribution of the 50th percentile (median map, which is the reference map for every probability of exceedance) and the distribution of the 16th and 84th percentiles, which give the variability of each estimate.
