Abstract
Seismic recordings from Peaceful Nuclear Explosions along six long-range profiles in northern Eurasia reveal the presence of an intermediate discontinuity in the mantle transition zone (410–660 km depth) at 530–555 km depth. In addition, between 200 and 300 km depth beneath the younger East European platform, Uralides and West Siberian basin a prominent low velocity zone (perhaps the asthenospheric layer) is identified which seems to be absent under the older East Siberian platform.
