摘要：

The velocity-depth distribution beneath central and eastern Europe is studied using travel-time data of a near-surface, well-located seismic event in central Europe and those of some underground nuclear explosions in the Soviet Union. The velocity-depth function obtained supports the hypothesis that lateral velocity variations in the upper mantle between the East European platform and central/southern Europe exist. From the observed heat flow field in Europe and the evaluated temperature-depth distribution, lateral velocity variations in the upper mantle can be explained by lateral variations of the temperature and the viscosity. © 1979.
