The present paper is the attempt to generalize the results of extensive study of local soil conditions influencing earthquake motion in the territory of the Republic of Moldova. It has been shown that for specific regional conditions such factors as thickness of soft soil, shear waves velocity, high impedance contrast between the clay-sandy layers and limestone basement play a decisive role in forming the amplitude level and spectral composition of motions occurring on surface. It has also been established that the influence of waterlogging, lithology is less than traditionally adopted.The unusually high level of damage to modern structures has been observed, resulting from resonance phenomena pertinent to soil-structure system.Regional methodology of seismic microzonation based on a complex study of soil dynamic properties is being advanced.The results obtained may be of use in solving problems of seismic microzonation and soil profile types classification.
