Profiling of the recent deposits of Nafplio coastal plain (Greece) from engineering geological modelling and geophysical surveys

In the current paper, some preliminary results from the research performed in the EU funded project “STABLE: Structural Stability risk assessment”, which aims to develop a methodology and tools to determine the seismic vulnerability of buildings in historical centres, are presented. The area of the historical centre of Nafplio was selected as case-study since it is one of the most important historical centers in Greece and a not negligible local seismic response may be expected based on the geological and geomorphological setting. The geological - geotechnical conditions in the study area were collected and evaluated and a geological model was identified. For this study, seismic noise measurements have been performed in the coastal plain where the town is built and processed with output resonance varying from 1 Hz up to 5 Hz, moving from the coastline towards the Acronafplia ridge. The results will be used to perform a structural stability analysis of the historical buildings using a simplified approach for specific earthquake scenarios in the future.
