Summary:
In the current bachelor thesis, the seismic hazard in the broader area of Messinia (SW Peloponnese) is assessed using probabilistic methods. The study area includes important tectonic structures, such as the horst of mountain Taygetos, Sparta’s fault, Kalamata’s graben and part of the Hellenic arc located south and west of Messinia. The region has hosted large earthquakes, as the 1986 Kalamata earthquake and the 2008 Methoni seismic sequence. Seismic hazard assessment in terms of Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV) and Peak Ground Displacement (PGD) was performed taking into consideration Gumbel’s extreme values theory via HAZAN software and the Cornell – McGuire approach, which is broadly utilized worldwide recently, using the latest version of the CRISIS software (R-CRISIS V20). The obtained results of the two methodologies are compared, as well as with previous studies. The final results of the Cornell - McGuire approach are obtained via a GMPE model constructed via a logic tree approach from other hybrid GMPE models in order to reduce computation uncertainties. Last, the Uniform Hazard Spectrums (UHS) for the five most populated cities in the study area (Kalamata, Messini, Pylos, Filiatra and Kyparissia) are obtained and compared to those proposed by Eurocode 8, the National Building Code and SHARE.
