Abstract
Summary
The aim of this paper is to highlight the indispensable significance of the geophysical and engineering-geological surveys of the local subsoil, for an effective and successful Liquefaction Hazard Assessment.
Albania, the small country in the western Balkan, is a disaster-prone country. Located next to the most active fault in Albania, the main cities of the country have experienced seventeen (17) seismic events with magnitude from 5.4 to 6.6 in the last 114 years. The last earthquakes that hit Albania on September 21st, 2019 of Mw 5.4 and November 26th, 2019 of Mw 6.2 severely damaged the cities of Durrës and the villages around.
The focus of this study is to examine the soil properties and liquefaction potential of the coastal area of Durres located in a critical tectonic zone that can produce large earthquakes, such as November 26th, 2019. To this aim, 50 Cone penetration testing with pore pressure measurement (CPTu) and 35 surface wave measurements (MASW) were employed. This approach can provide extensive data about estimated values of physico-mechanical properties of the underground layers of sand, silt, clay and peat deposits, which are usually unavailable in traditional approaches and which can be directly used in geo-technical stability calculations
