The sequence of two major earthquakes with moment magnitudes of 6.0 and 6.1 that hit the is-land of Cephalonia in Greece in 2014, resulted in significant liquefaction of gravelly soils. Two of the island’s main ports, Lixouri and Argostoli, were impacted by the liquefaction of gravel-size fills and experienced significant lateral displacements (up to 1.5 m). In this study, investi-gations were conducted using the Dynamic Penetration Test (DPT) with energy measurements and the Multi-Channel Analysis of Surface Waves (MASW) technique to measure shear wave velocity (VS). In both ports, the DPT results show relatively low N′120 values (<10 blows/30 cm). Liquefaction triggering analyses using the DPT indicate that liquefaction would be ex-pected at both ports. Triggering analyses using Vs-based methods indicate that liquefaction should have occurred in Lixouri, where the accelerations were higher, but not in Argostoli where VS values were higher than 225 m/sec. The results of this study confirm the need for a revised liquefaction triggering methodology for gravelly soils.
