Abstract
The analysis of differential travel-time residuals of reflected PcP and PKiKP waves that probe the core regions under Eurasia, Southeast Asia, and South America indicates a mosaic picture of the surface properties of the inner core, including large-scale and small-scale lateral inhomogeneities. A strong anomaly has been discovered under the Caspian Sea.
