Definition of Mohorovičić discontinuity in English:

Mohorovičić discontinuity


  • The boundary surface between the earth's crust and the mantle, lying at a depth of about 10–12 km under the ocean bed and 40–50 km under the continents.

    • ‘The Mohorovicic discontinuity, or Moho, the first major boundary of the earth's interior, separates the crust from the underlying mantle.’
    • ‘These values suggest that the Mohorovicic discontinuity remains relatively deep, 40 to 45 km, beneath western half of the transect.’
    • ‘Wide-angle reflection and refraction seismic data can be used to image the Mohorovicic discontinuity and provide information on the velocity structure and physical properties of the crust.’
    • ‘This seismic boundary is known as the Mohorovicic discontinuity.’
    • ‘The sharp boundary between the crust and mantle is called the Mohorovicic discontinuity or Moho.’


1930s: named after Andrija Mohorovičić (1857–1936), Yugoslav seismologist.
