Mountains larger than Mount Everest and rougher than Tibet likely lie deep beneath Earth's surface, a recently published study has revealed. Researchers from the Institute of Geodesy and Geophysics in China and at Princeton University in the US state of New Jersey have used seismic-wave data from a 1994 massive earthquake in Bolivia to examine a layer of rock located some 660 kilometres beneath the Earth's surface, according to Science Daily. A very strong powerful earthquake is necessary for this type of research, the study team noted, and the Bolivian earthquake is the second-strongest earthquake ever recorded.
