How was the moho discovered?

In: Geology [Edit categories]

Answer:

In 1909, the Croatian scientist Andrija Mohorovičić discovered the boundary between the crust and the mantle he found the depth between 30 to 35 km below the surface.
Moho was identified through seismograms observation from shallow focus earthquakes having two sets of waves. P-waves followed a direct path near the surface of the earth but S-waves got refracted by a high velocity medium. The layer below the crust and above upper mantle termed as Mohorovicic Discontinuity is called Moho.
A self-descending tungsten capsule heated by radiogenic heat to explore the interior of Earth near the Moho discontinuity and in the upper mantle is being considered by Japan and others for full discovery .
The discovery efforts aimed at reaching the discontinuity through US project Mohole and Soviet Union project after identification by Croatian Seismologist in 1909 still remains an important scientific objective.
