Probabilistic and Scenario-Based Seismic Hazard Assessment on the Western Gulf of Corinth (Central Greece)

The Gulf of Corinth (Central Greece) is one the most rapidly extending rifts worldwide, with its western part being seismically active, hosting numerous strong (M ? 6.0) earthquakes that have caused significant damage. main objective this study was evaluation seismic hazard through a probabilistic and stochastic methodology. implementation three seismotectonic models in form area source zones via logic tree framework revealed expected level peak ground acceleration velocity for return periods 475 950 years. Moreover, PGA values were obtained simulation motion by adopting worst-case scenarios potential earthquake occurrences known active faults area. Site-specific analysis populated urban areas (Patras, Aigion, Nafpaktos) performed constructing uniform spectra terms spectral acceleration. relative contribution each selected fault segment to characterizing site evaluated response adopted scenarios. Almost all parts found exceed reference value proposed current Greek National Building Code; however, are covered Eurocode 8 regulations.
