Seismic Intensity depends on soil conditions

The determination of the spatial distribution of the released

energy from the focus to a given point is known as an attenuation

problem. The main task being to determine the value of a given parameter

defining the earthquake effects at a given site (intensity, maximum acceleration,

velocity or displacement) as a function of the parameters describing the

size of earthquake (magnitude, epicentral intensity, seismic moment) the

distance, and the soil conditions at site. 1456 data points have been

collected from the Atlas of Isoseismal Maps (Catalogue of Earthquakes UNDP/UNESCO Survey of Seismicity of the Balkan Region) and from the Survey

of Seismicity of Macedonia up to 2002 year.

Keywords:Intensity, soil condition, attenuation,probability approach.
