Huge Earthquake in Bolivia Has Revealed Vast Mountain Ranges Below Earth's Surface
MIKE MCRAE 15 FEB 2019
Classic sci-fi writer Jules Verne once imagined a whole subterranean landscape deep inside the planet, complete with lost prehistoric species and plant life. The book was aptly titled Journey to the Centre of the Earth.
We might not actually find dinosaurs down there, but new research is revealing features in the underworld resembling structures on the surface. Far from a bubbling hot mess, there are mountains deep below rivalling anything up here.
Geophysicists from Princeton University in the US and the Chinese Academy of Sciences used the echoes of a massive earthquake that struck Bolivia two decades ago to piece together the topography deep beneath the surface.
On 9 June 1994, an 8.2 magnitude tremor rocked a sparsely populated region of the Amazon in the South American nation. Nothing this powerful had been seen in decades, with shocks being felt as far away as Canada.
