stress changes associated with the February 24 earthquake show increases on the fault segments that ruptured during the other two events. Damage The effects of the first two earthquakes are treated together due to their close spacing, with a single isoseismal map being produced. The area of violent shaking (level IX MMI) was along the southern coast of the Akyonides Gulf, with a much larger area experiencing severe shaking (level VIII MMI) extending from Xylokastro in the west to beyond Megara in the east, including the city of Corinth. The area of very strong shaking (level VII MMI) included Athens, with some parts of the city experiencing shaking of VIII to IX depending on ground conditions. The final earthquake also produced an area that experienced shaking of IX MMI, including the villages of Kalamaki and Plataies. The area of level VIII shaking included the city of Thebes. In total the earthquake sequence caused the destruction of 7,701 buildings (of which 1,175 were in Athens) with a further 20,954 being seriously affected (7,824 in Athens). Three administrative areas were affected, Attica, Beotia and Corinthia. The number of fatalities was in the range 20–22, with between a further 400 and 500 people injured. Both onshore and offshore areas were affected by landslides with one large underwater slump possibly the cause of the observed local tsunami. Liquefaction and ground fissures were reported from several areas.
