The present study is a probabilistic seismic hazard assessment in terms of well known engineering
parameters and is presented for the first time for the region of Greece. The following ground motion
parameters have been investigated and mapped using the recently published attenuation relationships
(predictive equations) of [Danciu & Tselentis, 2007], based on strong motion recordings of Greek
earthquakes: peak ground acceleration (PGA), peak ground velocity (PGV), spectral velocity (Sv) and
elastic input energy (VEi) for 0.2 and 1 sec, Arias intensity (Ia), cumulated absolute velocity (CAV),
CAV5 and spectral intensity (SI).
The resulted maps portrait the spatial distribution of estimates of the engineering ground motion
parameters that occur with a probability of 10% in 50 years (475 years return period).
