Croatian seismologist Andrija Mohorovičić is credited with discovering and defining the Moho. In 1909, he was examining data from a local earthquake in Zagreb when he observed two distinct sets of P-waves and S-waves propagating out from the focus of the earthquake. Mohorovičić knew that waves caused by earthquakes travel at velocities proportional to the density of the material carrying them. As a result of this information, he theorized that the second set of wave… Webnoun, plural dis·con·ti·nu·i·ties. lack of continuity; irregularity: The plot of the book was marred by discontinuity. a break or gap: The surface of the moon is characterized by … noted vegas entertainers of the 90sWebThe scale effect was evaluated by analysing discontinuity profiles of different lengths (10 cm, 30 cm, 60 cm and 100 cm), with measurements taken from drone flights flown at different distances from the rocky slopes (10 m, 20 m and 30 m). ... including engineering geology.
