The earthquake hit the area at 1525 EET (1325 UTC), with a moment magnitude of 6.5, according to the Athens Geodynamic Institute.

Interior Minister Prokopis Pavlopoulos dispatched rescue and recovery teams (including members of five government agencies), the Red Cross and units of the army in order to assess the damage and the needs of survivors in the earthquake affected areas.

The focal mechanism of the earthquake of June 8 is consistent with the shock having been caused by strike-slip faulting similar to that occurring within the northeast-trending zones.

Since the beginning of the twentieth century, the largest crustal earthquakes of central Greece have had magnitudes of about 7.2.

[6] This earthquake generated enough power to cause damage to structures over an area of 2000 square kilometers.

Heavily affected villages by this natural disaster were Portes, Santomeri and Valmi.

There is account of limestone rock falling from this mountain, which struck a house in the village of Santomeri and caused serious structural damage, but there were no casualties in this incident.

Along with the evacuation, some of the damage done to the Kato Achaia train station has been repaired in the form of replaced rails within two days of the occurrence of the earthquake.
