Assessment of Liquefaction Hazard and Mapping Based on Standard Penetration Tests in the Long Beach and Tuzla Regions of Cyprus

Cyprus is the third largest and populated island in Mediterranean Sea, still rapidly expanding. Significant infrastructures, such as hotels, educational institutions, large residential complexes, are being built. Historically, 15 destructive earthquakes were reported on from 1896 to 2019 that caused structural damages casualties. In this study, liquefaction potential of Tuzla Long Beach east coast estimated using standard penetration test (SPT) data more than 200 boreholes at different locations sites. The overall results presented a index obtained factor safety (F.S.) coefficient. Both study areas susceptible liquefaction. Thus, maps prepared identify hazards Beach. Additionally, average line was introduced for both sites create correlation between area F.S. values every borehole. adopted approach precisely provides liquefiable regions when compared with historical evidence, CPT measurements, surface geology aspects, geospatial data. prove must be considered during design stage new infrastructure these areas.
