Review on seismic hazard assessment in Greece

ABSTRACT

In this presentation a review of the methodologies and techniquess applied in Greece for seismic hazard assessment and strong motion simulation are presented and discussed. Emphasis is given to the uncertainties involved and to the limitations of the useability of the results. In estimating the expected maximum ground motion parameters, two main approaches are used the pure statistical and the semi-statistical approach in the sense that before applying a cetain earthquake occurrence law, the modelling of the seismic sources based on seismotectonic criteria and their potentiality is evaluated. For comparison reasons, all the above methodologies are applied in estimating the seismic hazard of the city of athens, the capital of Greece. The results expressed in PGA having 90
