Assessment of Soil Liquefaction Potential Based on Standard Penetration Test Data Under Different Earthquake Magnitude Scenarios: A Case Study of Ergene 1 Organized Industrial Zone, Türkiye
Year: 2026
Type: article
Abstract: This study evaluates soil liquefaction potential in the Ergene 1 Organized Industrial Zone, Türkiye, using 1880 Standard Penetration Test records from 411 boreholes distributed across 49 industrial parcels. Liquefaction triggering was assessed for Mw 6, 7, and 8 earthquake scenarios with the Turkish Building Earthquake Code and the Boulanger–Idriss procedures. Possible severity level was classified by using reference indices previously published. The Boulanger and Idriss procedure produced the more conservative results: Parcel 233/1 was identified as potentially liquefiable at Mw 6, Parcels 233/1 and 237/16 at Mw 7, and both parcels remained critical at Mw 8. The code-based procedure identified liquefaction only at Parcel 237/16 under the Mw 8 scenario. Factor-of-safety profiles show that the critical layers are shallow, generally within the upper 7–9 m, where loose sandy–silty strata coincide with a shallow groundwater table. Geographic Information System maps generated by inverse distance weighting further demonstrate the spatial association between groundwater conditions and liquefaction susceptibility. The integrated workflow provides a practical framework for parcel-scale screening and seismic risk management in organized industrial zones with similar geological and hydrogeological settings.
