Shear Wave Velocity in the Top of the Earth’s Inner Core

Shear Wave Velocity in the Top of the Earth’s Inner Core

Analysis of PKIIKP waves reflected off the inner surface of the solid core boundary and recorded close to the antipode indicates that the shear wave velocity at its top can be 10–60% below the value of 3.5 km/s envisaged by standard models of the Earth.
