Measuring the seismic velocity in the top 15 km of Earth’s inner core

Godwin, Harriet; Waszek, Lauren; Deuss, Arwen

Description

We present seismic observations of the uppermost layer of the inner core. This was formed most recently, thus its seismic features are related to current solidification processes. Previous studies have only constrained the east-west hemispherical seismic velocity structure in the Earth’s inner core at depths greater than 15 km below the inner core boundary. The properties of shallower structure have not yet been determined, because the seismic waves PKIKP and PKiKP used for differential travel...[Show more]
