Design earthquakes and conditional hazard
WebPGA and the corresponding design earthquake in terms of magnitude and distance from hazard disaggregation. Two percentiles (i.e., the fiftieth and the ninetieth) were extracted fromthe conditional probability density function (PDF)ofID given PGA and mapped for the Campania region (southern Italy). The selected hazard level for PGA corresponds to a WebThe uniform hazard response spectrum (UHS) and the deaggregation of the hazard form the starting point for the preparation of target spectra for the development of ground motion time histories. The earthquake events that dominate the hazard in the period range of importance for the structure for the specified annual probability are
