Scientists Discovered Mountains 410 Miles Deep Into The Earth

In schools, they teach us that the Earth is composed of three layers: the crust, the mantle, and the core, which is further subdivided into the inner and outer core. However, new research has shown that deep down there may be other layers.

In a study published in ScienceDaily, geophysicists Jessica Irving, Wenbo Wu, and Sidao Ni released a discovery that could change everything we know about the Earth and its layers.

The scientists used seismic waves from a massive earthquake in Bolivia in 1994 to discover a new layer at the depth of 410 miles. Between the upper and lower mantle there are mountains, just as those on the surface.

This new layer discovered by the researchers doesn’t have a formal name yet, so they simply refer to it as "the 660-km boundary."

The only way to see this deep into the Earth is through waves generated by large earthquakes.

Big quakes are so much more powerful than their smaller counterparts. With every step up the Richter scale, the energy increases 30-fold. Deep earthquakes can get the whole mantle going.

According to the scientists, more accurate information can be obtained from earthquakes that are magnitude 7 or higher. Their shock waves propagate in all directions and can go through the core to the other side of the planet and back. The earthquake used for this research remains the second largest ever recorded.

Nowadays, there are more seismometers than 20 years ago, which helps study the behavior of waves in the Earth's depths.

This finding is huge! And just when we think that we know everything about our planet by now!
