Event narrative

On Saturday 13th September 1986, at 20:24 local time, an earthquake of moment magnitude 5.9 and focal depth of 22 km struck the town of Kalamata in the Messinia prefecture of southern Peloponnese, Greece.

The main shock’s epicentre (37.07°N, 22.18°E) was very near Kalamata. Damage was extensive in most parts of the town, as well as some nearby villages and 20 people lost their lives while 330 were injured (82 of which required hospitalization).

Many aftershocks followed, the greatest of which occurred two days later and was centred within the town limits and had surface-wave magnitude 5.4 and focal depth 8 km. This aftershock caused an additional 37 injuries and further damage to the already weakened buildings.

Overall impact

Kalamata, capital town of the Messenia prefecture, was at the time inhabited by around 43,000 people and spread over an area of around 10 km2. The damage distribution was not uniform across the town, with severe damage concentrated in the central and northeastern parts of the city, coinciding with the historic town centre where old masonry buildings prevailed. Damage near the harbour and the coast was limited. This spatial variation in damage severity was attributed to soil conditions as well as source and directivity effects due to the causative fault’s proximity.

Six people lost their lives in the pancake-type collapse of a 5-story reinforced concrete apartment building. Sixteen people were rescued from the rubble of this building. Twelve more people died and several hundred were injured, in Kalamata, mostly due to falling debris. Casualties were reduced in the city because a large crowd of about 5,000 people was gathered in the open air on the waterfront for the inauguration of a new ferry liner connecting the region with the island of Crete.

Damage outside of Kalamata was highly localized with severe destruction concentrated in a few villages situated between 5 and 15 km from the city. In Elaiochori, a small village (population 355 people), approximately 30 per cent of the rubble stone masonry buildings disintegrated completely, but only two people were killed, because most of the village residents were attending the dedication of an icon and were gathered in the open air outside the village chapel at the time of the earthquake’s occurrence.

Approximately 3150 buildings were destroyed and 10,000 people were rendered homeless. The cost of the earthquake was estimated at about 750 million US$.
