The full name of the Moho surface is the Mohorovicic Discontinuity, which is the boundary between the crust and the mantle. It was first discovered by the seismologist Andrija Mohorovicic in 1909, who realized that seismic waves accelerated in a zone located 50 km beneath the Earth’s surface, which was interpreted as a geological discontinuity. Later, this zone was proven to be present not only below Europe but globally at various depths. It is shallow beneath the oceans (usually 5–15 km) and deep beneath the continents (generally 30–35 km). It is deepest (60–70 km) beneath the Qinghai-Tibet Plateau and Tianshan areas.
