At school they do not teach that the Earth is divided into three layers, which are the crust, mantle and core, which in turn is divided into inner and outer core. A basic and successful scheme, but nevertheless leaves out other more subtle layers that scientists are now beginning to identify the deep interior of our planet. A good example is the study published this week in Science, in which geophysicists Jessica Irving and Wenbo Wu, of Princeton University, in collaboration with Sidao Ni, the Institute of Geodesy and Geophysics of China, they succeeded in using seismic waves a major earthquake in Bolivia to locate, 660 kilometers deep, a new "layer" that has wowed them a mountain range, very similar to the ones on the surface.
To observe what happens so deep, the researchers used the most powerful waves that exist on our planet, seismic waves generated by massive earthquakes.Earthquake in Bolivia For this particular study, key data were obtained from captured waves after an earthquake of magnitude 8.2, the second most powerful ever recorded, which shook Bolivia in 1994. "The so large earthquakes do not appear very Irving says often, and now we are fortunate to have many more seismographs than 20 years ago. These tools and computational resources, seismology is now a completely different country as it was two decades ago. "
With a magnitude on the Richter scale of 8.2 Mw earthquake in La Paz in Bolivia (1994) it is framed as one of the most devastating in history. A tremor that lasted several cities in South America and caused millions of dollars in damage. It is also one of the deepest earthquakes ever recorded with a length of 641 kilometers. In this case, the researchers used the supercomputers Tiger group of Princeton University to simulate the complex behavior of seismic waves scattered in the depths of the Earth.
The technology used for this analysis depends almost entirely on a unique property of waves: their ability to bend and bounce. Thus, just how light waves can bounce (reflected) in a mirror or bending (refracting) when passed through a prism, seismic waves travel directly through homogeneous rock, but is reflected or refracted when They find a limit or roughness.
Giant Mountains
Geologists were surprised by the "roughness" of this new layer, which was even more pronounced than we see in the surface layer (crust) on which we all live. "In other words Wu explains the limit of 660 kilometers stronger than the Rockies or the Appalachians topography is present."
The statistical model developed by scientists could not establish accurately the heights of these mountains, but in his article said that could be larger and higher than any other on the surface of the Earth.
