At the 8th of June 2008, 12:25:28.0 UTC, earthquake of ML=6,5R and D=15-21km stroke at the North-western Peloponnesus area (37.97N, 21.48E).

According to the existing data, the earthquake was expressed by a fault trending N20°E, of dextral strike slip character, in 15-21km depth, while the aftershocks arrangement follows the same general trend. From the investigation that took place in the area, the expression of the seismic faults on the surface that pertain with the instrumental data were allocated, while the geological and geotechnical status of the area was determined as well.

A detailed mapping and study of the damage distribution, as well geodynamic phenomena took place. Combining all the above mentioned, the intensities for every residential area came along according to EMS scale (1998) and so the intensity distribution in the misoseismal area.

Based on the cross-correlation of all the existing data it is concluded that the seismotectonic, geological and geotechnical regime were determinant to the damage and intensities distribution.
