Summary:
The earthquakes of 1978 in Thessaloniki and of 1981 in Athens led to the establishment in 1983 of the Organization for Antiseismic Planning and Protection (O.A.P.P.). At all subsequent significant seismic events in Greece, the Organization has taken part in the administration of the emergency events, as link between the State, the citizens, the technical manpower of the country, research and academic establishments. In 1986, a catastrophic earthquake 6,2 R in Messinia caused fatalities, significant damages to buildings and the infrastructure, with social and economic repercussions. In 1988, a powerful earthquake 6,0 R in Ilia, caused significant damages to the Kyllini port, Bartholomio, the historic castle, earth liquidization at the estuaries of Pinios river and movement of shore lines. In 1995, a powerful earthquake 6,6 R hit Grevena and Kozani. Many villages were destroyed. There were injuries, building collapses and various damages due to the seismic vibration. In 1995 also, a powerful earthquake 6,2 R in Aegio, caused a lot of fatalities and serious material damages, collapse of a block of flats and a hotel, earth cracking and liquidization, share detachment and landslides. In 1999, the earthquake in Athens of 5,9 R, caused also a lot of fatalities and significant damages to buildings and infrastructure. In 2003, a powerful earthquake 6,4 R in Leukada Island, caused damages to buildings, monuments, ports and rock falls. In 2006, a powerful earthquake 6,9 R at the sea area of Kythira and Antikythira islands, caused damages to (mainly) old houses, the square, the church, and rock falls. In April 2007, seismic vibrations at the size of 5 and 5,4 R at Trichonida lake in Aitoloakarnania, caused crackings to buildings and damages to villages. In 2008, the powerful earthquake 6,5 R at N.W. Peloponnese, mainly at Ilia and Achaia, caused fatalities, injuries and damages to buildings, the railway network as well as rock falls and soil liguidization. In August 2013, a powerful earthquake 5,1 R in the area of Amphikleia – Reginio in Pthiotida, caused crackings, power interruptions, etc. In January 2013, at the strong scismic vibration 5,8 R in the sea area 44 km East of Limnos island, there were no reports for damages.

In 2014, strong seismic vibrations 5,8 and 5,7 R in Kefalonia island, caused damages to buildings and infrastructure (Lixouri port), rock falls, landslides and earth crackings. In 2015, the powerful seismic vibration 6,0 R with epicentric area 13 km West of Leukada island, caused two fatalities and rock falls. In 2016, a powerful seismic vibration 5,3 R, with epicentric area 12 km NW of loannina followed by a seismic sequence of about 2 months, caused rock falls. In 2017, a powerful earthquake 6,1 R at the sea area 34 km SW of Lesbos island, caused one fatality and extended damages to buildings. In 2017, a powerful earthquake 6,2 R at a focal depth of 10 Km, 23Km NE of Kos island, caused fatalities, injuries, damages to buildings, monuments and the main port of the island.
