1. (Geological Science) the boundary between the earth's crust and mantle, across which there is a sudden change in the velocity of seismic waves. Often shortened to: Moho. [C20: named after Andrija MohoroviÄiÄ (1857-1936), Croatian geologist].
The Moho is located between the crust and the mantle, about 30/40 km below continental regions and 7-10km below ocean ridges. What is the seismic evidence for the existence of the Moho? The seismic evidence for the Moho's existence is that seismic waves traveling for most of their path in the mantle reach a distant seismograph first.
