On November 17, 2015, an Mw 6.4 earthquake struck Lefkas Island (Ionian Sea, Western Greece) with epicenter located 20 km southwest of Lefkas town. It caused 2 fatalities, 8 injuries, earthquake environmental effects (EEE) and damage to buildings and infrastructure. Ground cracks, slope movements and liquefaction were observed in western Lefkas. The highest intensity VIIIESI 2007 was assigned to large-volume slope movements along the western coastal part of Lefkas. Damage to buildings was mainly observed in Dragano-Athani graben in southwestern Lefkas. Masonry buildings and monumental structures suffered the most, while traditional buildings with dual structural system performed well. Reinforced-concrete buildings were not affected. The highest seismic intensities VIIIEMS-98 were assigned to villages of Dragano-Athani graben. Based on historical and recent earthquake data and the field observations on the 2015 Lefkas earthquake, it is concluded that the western part of the island is the area usually affected by earthquake effects including landslides and rock falls, liquefaction phenomena, small-scale subsidence and tsunamis.
