摘要
1-D models for the quality factor along a few profiles crossing the Vrancea region and the adjacent extra-Carpathian zone have been recently developed, to reconstruct the ground motion generated by weak-to-moderate crustal earthquakes of Vrancea. The retrieved Q-structures reveal a consistent pattern of high attenuation at the bend of the Southeastern Carpathians. We discuss this result in relation with the outcomes of several studies that analyze wave attenuation along travel paths crossing both crustal and upper mantle structures of the study region, to emphasize the contribution of the shallow structure to the observed attenuation pattern.
