Seismologists have detected a unusual body of water deep within the earth's crust in the deep mantle near the earht's core. When seismic waves traveling through the planet due to earth movements reach East Asia, they area slow down slightly and attenuate due to the large quantity of water stored in the rock. The heart of the phenomenon is almost right underneath the city of Beijing, China, hence the name. The quantity of water found is quite substantial, the equivalent of another Arctic Ocean. 600,000 seismograms from all over the earth were analyzed in making the find.
What will they find out next?
