WebbInnermost Inner Core. Travel-time anomalies of waves traversing the inner core indicate that the directional dependence of wave propagation within the inner core is generally fast for waves travelling in the north-south direction, and low for waves travelling in the equatorial plane. This is consistent with normal-mode splitting data. Webb21 okt. 2002 · The solid inner core (Fig. 1) is the most remote and enigmatic part of our planet, and, next to the crust, is the smallest “official” subdivision of Earth's interior.
