ANDRIJA MOHOROVICIC (1857 - 1936) Mohorovicic was born in Volosko, Croatia. He was educated in numerous fields of study such as philosophy, mathematics, geophysics and astronomy, but he showed particular interest in meteorology and seismology. He was a brilliant lecturer and researcher at several universities and scientific institutions in his country and other neighbouring countries.
ANDRIJA MOHOROVICIC (1857 - 1936) He made his main contribution to earth sciences as a result of an earthquake in a region close to Zagreb where a number of seismographs had been previously installed. Data from these instruments made Mohorovicic realise that seismic waves vary their speed as they spread through the inside of the Earth because the composition of the environment varies with depth. This led him to conclude that the Earth consists of surface layers around the inner core.
ANDRIJA MOHOROVICIC (1857 - 1936) With more precise measurements, he discovered evidence of a sharp increase in the speed of seismic waves, which he placed at about 54 kilometres below the Earth's surface. He attributed this to a higher rock density. Years later, scientists found that this record of the Earth's interior can be detected all over the planet. It was named the Mohorovicic discontinuity (or Moho for short) and marks the boundary between the Earth’s crust and the rigid outer mantle. Depth Speed of seismic waves Go back
BENO GUTENBERG (1889 - 1960) Gutenberg was born in Darmstadt, Germany. He was educated at the University of Göttingen, where he was a student of another notable geophysicist, Emil Wiechert, who also played a role in the discovery of seismic discontinuities. He carried out much of his scientific work in the United States, working with the best teams at that time to detect seismic waves. He collaborated with other notable seismologists such as Richter and Benioff.
BENO GUTENBERG (1889 - 1960) His main contribution to earth sciences was measuring the diameter of the Earth's core by placing the boundary between the mantle and the core at a depth of 2900 km. He deduced this from data on the variable speed of seismic waves at that depth (P waves decreased dramatically in speed, while S waves ceased to be transmitted on coming into contact with the molten metal outer core). This seismic irregularity, known as the Gutenberg discontinuity, was named after him. in oceans Go back
INGE LEHMANN (1888 - 1993) Lehmann was born in Østerbro, Copenhagen, in Denmark. She studied mathematics in Copenhagen and Cambridge and later began her work in seismology. From 1953 she continued her scientific career in the United States, where she received numerous honours and awards for her research. In 1971, she was presented with the William Bowie Medal, the American Geophysical Union's highest honour, which is granted to scientists who have made fundamental contributions to the study of geophysics.
