Did you know?
WebAndrya Mohorovicic determined the boundary between the crust and the mantle, which is now named the Mohorovicic discontinuity. Velocities of seismic waves were used to identify this boundary. He had seismographs installed before the 1909 earthquake had occurred. The Mohorovičić discontinuity was first identified in 1909 by Mohorovičić, when he observed that seismograms from shallow-focus earthquakes had two sets of P-waves and S-waves, one set that followed a direct path near the Earth's surface and the other refracted by a high-velocity medium.
