New Developments in Probabilistic Seismic Hazard Analysis: Common Problems and their Resolution

The purpose of this short paper is to highlight and discuss several frequent problems which one faces in Probabilistic Seismic Hazard Analysis (PSHA). The potential difficulties are:<br>- how to take into account the incompleteness of seismic event catalogues,<br>- how to handle the uncertainties within the seismic event catalogues,<br>- how to take into account the inadequacies inherent in the selected model of seismicity,<br>- how to delineate seismogenic source zones.<br>The lecture attempts to address the above problems, to provide tools for their solution and to present a coherent methodology for efficient assessment of PSHA.
