The Daily Galaxy: News from Planet Earth & Beyond: "NASA's 'Journey' to the Center of Earth
Earths_coreKnowing the location of the Earth's center of mass provides the frame through which NASA's scientists determine the relative motions of positions on Earth's surface, in its atmosphere, and in space.
This information is vital to the study of global sea-level change, earthquakes, volcanoes, and Earth's response to the retreat of ice sheets after the last ice age.
In 1864 Jules Verne published his classic Journey to the Center of the Earth. The novel tells the story of a professor who leads his nephew and hired guide down a volcano in Iceland to the 'center of the Earth'. En route they encounter prehistoric animals and natural hazards, eventually coming to the surface again."
