Over 4000 arrival times at WWSSN stations in Europe from earth-quakes in the Eastern Mediterranean and from presumed Russian nuclear explosions are used to define first arrival travel-time curves for the region. Travel times within Europe show no broad regional variation and are considerably slower than those predicted by published velocity models for Fennoscandia and the Russian Platforms. The travel times from the Russian explosions differ only slightly from the European ones and it is concluded that the transition to a region of higher average velocity occurs far enough east for most of the data in this study to be representative of the lower, ‘European’, velocity structure.
