Abstract:
A new technique is developed to perform a deterministic hazard analysis in terms of physical parameters, i.e. displacements, velocities, maximum accelerations, and civil engineering specific ones, design accelerations. The method is adapted for the specific features of the Romanian Plain seismicity including the latest theoretical results in both seismotectonic and prediction fields, and data acquisitions. The deterministic analysis is performed computing free surface synthetic seismograms corresponding to different seismic sources and structural models, for crustal and intermediate-depth events separately. The DGA (design ground acceleration) greatest values and the NS and EW components resultant for the velocities and horizontal displacements are considered as a measure for seismic hazard level. © 2006 Akadémiai Kiadó, Budapest.
