Earthquake
The earthquake struck west of Lefkada island with initial magnitudes of between 6.3 and 6.7 however it was later settled to 6.5 according to the United States Geological Survey. The earthquake was generated by a strike-slip rupture on the Cephalonia-Lefkada Transform Fault, which also produced earthquakes in 2003 and 1973.Λευκάδα 2003 Ο.Α.Σ.Π. https://www.oasp.gr/node/497 2021-09-23 oasp.gr The Hellenic arc is known for its frequent seismological activity and generating historically large quakes in all of Southeastern Europe. Lefkada is located at the boundary between two geological zones, the Ionian and Paxos. This boundary runs through the western outcrops onshore the island, forming the noteworthy Ionian Thrust.Papathanassiou George Valkaniotis Sotirios Ganas Ath Grendas Nick Kollia El 2017-01-20 The November 17th, 2015 Lefkada (Greece) strike-slip earthquake: Field mapping of generated failures and assessment of macroseismic intensity ESI-07 https://www.researchgate.net/publication/312669021 Engineering Geology 220 13–30 10.1016/j.enggeo.2017.01.019 2017EngGe.220...13P Papathanassiou George Valkaniotis Sotiris Ganas Athanassios Grendas Nikos Kollia Elisavet 2017-03-30 The November 17th, 2015 Lefkada (Greece) strike-slip earthquake: Field mapping of generated failures and assessment of macroseismic intensity ESI-07 https://www.sciencedirect.com/science/article/pii/S0013795217300881 Engineering Geology 220 13–30 10.1016/j.enggeo.2017.01.019 2017EngGe.220...13P 0013-7952 subscriptionAthanassios Ganas Pierre Briole George Papathanassiou George Bozionelos Antonio Avallone Diego Melgar Diego Melgar Panagiotis Argyrakis Sotirios Valkaniotis Evangelos Mendonidis Alexandra Moshou Panagiotis Elias A preliminary report on the Nov 17, 2015 M=6.4 South Lefkada earthquake, Ionian Sea, Greece https://www.earthquakegeology.com/materials/reports/Lefkada_17_Nov_2015-Earthquake_Report.pdf earthquakegeology.com
Damage
Lefkada and other Ionian Islands
Most damage was observed in western Lefkada as well ground cracks, slope movements and liquefaction found in the area. Primary effects directly linked to surface expression of the seismological source were not detected in the field. A maximum intensity of VIII was assigned areas where to large-volume slope movements occurred, along the western Lefkas coast. Intensity VIII were also assigned to the villages located in Dragano and Athani due to very heavy structural damage observed on masonry buildings, churches and other weak infrastructure mainly attributed to the combination of the recorded high PGA values, the poor anti-seismic design and construction of buildings and the geological and tectonic structure of the affected area. Damage to buildings was mainly observed in these villages arranged almost parallel to the northern segment of the Cephalonia-Lefkada Transform fault. Among not earthquake proof structures, stone masonry buildings and monumental structures suffered most damage, while the traditional buildings of the area with dual structural system and with wooden frames performed relatively well and suffered minor damage. Reinforced concrete buildings were affected not so much by the earthquake itself but was worsened with ground liquefaction.The 17 November 2015 Mw 6.4 Lefkas (Ionian Sea, Western Greece) Earthquake: Impact on Environment and Buildings https://www.springerprofessional.de/en/the-17-november-2015-mw-6-4-lefkas-ionian-sea-western-greece-ear/15362392 2021-09-24 springerprofessional.de Part of a harbor in Vasiliki was said to have sunk and Schools in both Lefkada and Cephalonia were forced to shut down.2015-11-17 Two dead after earthquake hits Greek island of Lefkada https://www.ctvnews.ca/world/article/two-dead-after-earthquake-hits-greek-island-of-lefkada/ 2021-09-24 CTVNews
Egremni Beach
A flank of the well-known pristine Egremni Beach collapsed following the massive tremor. Fortunately, the event happened on the winter months thus meaning no people were harmed. Before the earthquake occurred a cliff in the beach has been known to have been in a state of decline due to the climatic forcing resulting from previous minor seismicity and erosion.Pappas Gregory 2015-11-18 Lefkada Loses One of the World's Most Beautiful Beaches in Earthquake: Dramatic Before and After Images https://pappaspost.com/lefkada-loses-one-of-the-worlds-most-beautiful-beaches-in-earthquake-dramatic-before-and-after-images/ 2021-09-24 The Pappas PostKoukouvelas Ioannis Κ.

Casualties
A 69-year-old woman died when a boulder from a loose mountain had hit her house. And an 82-year-old woman also died when a wall collapsed onto her. An estimated 4-8 people were hospitalized with further injuries.Tremors of Greek earthquake felt in Italy 17 November 2015 https://www.thelocal.it/20151117/powerful-earthquake-in-greece-felt-in-italy/ live 2021-09-24 https://web.archive.org/web/20151118144341/http://www.thelocal.it/20151117/powerful-earthquake-in-greece-felt-in-italy 2015-11-18
