Mohorovičić, Andrija
Born Jan. 23, 1857, in Volosko (Opatija), Istria; died Dec. 18, 1936, in Zagreb. Yugoslav geophysicist and seismologist. Member of the Croatian Academy of Sciences (1898). Mohorovičić began teaching meteorology at the Navigation School in Bakra and Zagreb in 1880. In 1897 he became a privatdocent, and in 1910 a professor at the University of Zagreb. From 1892 to 1921 he also served as the director of the State Administration for the Meteorological and Geodynamic Survey and Observatory in Zagreb. In 1909, Mohorovičić established the existence of a boundary surface between the earth’s crust and mantle, and this was named the Mohorovičić discontinuity. He worked out a method for recording earthquakes and proposed designs for a number of geophysical instruments.

No references found | One of the first results was the discovery that the ocean crust appeared to present a consistent, layered seismic structure composed of sediments (layer 1 at the seafloor) followed by two layers with rapidly increasing sound velocity, and then a reflector, dubbed the Moho after the its discoverer, a Czechoslovakian seismologist named Andrija Mohorovicic. Discovered in 1909 by yugoslavian seismologist Andrija Mohorovicic, the continental Moho resides at depths of 35 kilometers, where the speeds of seismic waves traveling through the earth abruptly change. When Croatian seismologist Andrija Mohorovicic published his landmark discovery of a shallow transition to a remarkably uniform layer of high sound (or seismic) velocities in 1909, he had, in fact, discovered the boundary between Earth's crust and upper mantle, which is now known as the Moho. |
