The SEAHELLARC project, supported by the European Commission, aims at evaluating and computing seismic hazard and risk, as well as modelling tsunamis for the town of Pylos, in the western Peloponnese. For this purpose, a new seismogenic zonation has been developed for the Pylos area, and broader region, and the most updated seismic hazard assessment is provided.

The difference obtained for the expected ground motion, with a 475-year return period, in the town of Pylos is not significantly big (it only decreases from 0.63 to 0.56 g using literature data or the new ones, respectively).

Abstract

The SEAHELLARC project, supported by the European Commission, aims at evaluating and computing seismic hazard and risk, as well as modelling tsunamis for the town of Pylos, in the western Peloponnese. For this purpose, a new seismogenic zonation has been developed for the Pylos area, and broader region, and the most updated seismic hazard assessment is provided. The present paper describes preliminary seismic hazard computations performed with the scope of testing the improvements made during the project. In particular, the influence of an updated version of the Greek earthquake catalogue and of a new seismogenic zonation for the Pylos region are presented. The difference obtained for the expected ground motion, with a 475-year return period, in the town of Pylos is not significantly big (it only decreases from 0.63 to 0.56 g using literature data or the new ones, respectively). Conversely, greater differences concern the Island of Zakinthos.
