How are seismic waves produced

WebStudents learn about the types of seismic waves produced by earthquakes and how they move through the Earth. The dangers of earthquakes are presented as well as the necessity for engineers to design structures for earthquake-prone areas that are able to withstand the forces of seismic waves. Students learn how engineers build shake tables that simulate … WebThe amplitude of the seismic waves is therefore proportional to the energy released and is a measure of the magnitude of the earthquake. It was Charles Richter, in 1935, who proposed a method for measuring the magnitude of earthquakes starting from the measurement of the amplitudes recorded by a particular torsion seismometer, the Wood …
