article_snippet: By recording seismic tremors, researchers are able to build a 3D picture of Earth's mantle - the layer between the crust and outer core.
article_snippet: The 3D models were created by Princeton University's Professor Jeroen Tromp who is aiming to create a map of the entire mantle - down to a depth of 1,865 miles (3,000km) - by the end of the year.
article_snippet: The resulting map could reveal the precise locations of tectonic plates, which can cause earthquakes when they move against each other.

article_snippet: The maps could also reveal the locations of magma that, if it comes to the surface, causes volcanic activity, the researchers said.
