Abstract

Seismic observations reveal that the Earth’s inner core oscillates with a period of approximately seven decades. The multidecadal periodicity coincides with that of several other geophysical observations, particularly the variations in the length of day and the Earth’s magnetic field, suggesting dynamic interactions between the major layers of the Earth.
